What's this BCM keymod handguard you speak of in your new video?

Haley Strategic Partners A product we're testing. If you take a class with us in the next month, you might see it first hand.

Logan W. Nice!

This looks like what the NSR could've been if Noveske wouldn't have had to retool to get KEYMOD on the 45s. I wonder how it will mount.

07-20-13, 15:51
I, too, am interested in finding out how it mounts. This might be the perfect addition to my BCM upper:)

07-20-13, 16:22
How do you say PWS and BCM make the Keymod rails, and some other people do as well, and fail to mention NOVESKE who were the first to use it on an AR platform? I shut it off after that.

The BCM rail looks good, but there aren't many ways to configure a Keymod so I think we will see a lot which look similar. The largest differences are going to be how wide a company goes and its attachment method.

07-20-13, 16:52
Yep. Not knocking BCM. Would never but Noveske was the first. I have an NSR on my primary rifle and am completely satisfied. KAC's offering does have 45 degree mounting positions which may make it more interesting.

Kincel going from Vltor to BCM does make Bravo's future with the key mod interesting. Not sure of how much Eric had on the keymod development but his recent employment to Bravo is a great plus to BCM nonetheless.

Agreed, it certainly isn't a knock against BCM, or even Travis, but it seems odd to talk about Keymod and not mention Noveske.

I think Eric had a lot to do with it, he is highly creative. He is certainly a large asset for BCM.

Travis has since said he was running on low/no sleep and to cut him some slack with the video. he didn't specifically mention noveske but I'm sure thats what he was referring to.

Obviously the rail is going to be skinny, and have keymods 360 around (well except the top rail of course). The question is, how skinny? How much will it weigh? and what sort of barrel nut/attachment will they use?

Oh don't forget cost. If they can sell this rail for under $200 they will clean house. They made a comp that rivals the battlecomp for 40% less $.

It sure is nice to see more Keymod support!
The BCM rail looked like a Knight's URX 4 to me at first, before he repeated it was a BCM. Keymod slots at the top 45* marks will be a welcome addition over the NSR, primarily for light placement.

Vltor (Led by Eric Kincel) was the sole developer of the KeyMod system and the associated standardized modular technology. Afterwards Eric Kincel (and Vltor) released that technology to every manufacturer in the industry for FREE. The idea was to help the industry move forward with a standard modular system. It is advancement for the warfighter. Vltor did manufacturer the very first KeyMod rail systems for a special .mil project. It was very well received. It was purchased in small quantities and still currently being tested. To my knowledge Vltor has not made that rail as a part their standard commercial offering.

John Noveske (being the smartest of the bunch) was the first commercial manufacturer to offer a KeyMod rail to the public. Many companies have joined with many more companies in development on a version.

The BCM KeyMod Rail (developed by Eric Kincel, now of BCM) is still in final phases of T&E development with a number of BCMGUNFIGHTER instructors. As such the specs and design have not been finalized. But I can say this; the BCMGUFNIGHTER KeyMod Rail will redefine tactical handguards the same way the BCMGUNFIGHTER Charging handle has redefined that market. -- pretty good tease?.... stay tuned :D

Yeah. If they can beat Noveske's pricing they will sell, sell , sell.

Wow, quite a statement. I'm really looking forward to seeing more. I'd guess that has to have something to do with the attachment method/anti-rotation.

Technical question on KeyMod for anyone who knows (and hopefully OP doesn't mind the hijack): why doesn't the skinny end of the key open back up slightly to provide a more secure slot for the attachment screws to secure to? That would prevent the attachments from sliding. Wouldn't that protect against counter-recoil and be a better method than relying on a little hook that goes in the next opening over?

The attachments don't slide in keymod and it doesn't need anti recoil protection any more than it already has.

Look at pictures of the under side of attachments to understand.

I wonder why they don't put keymod on the top (with some picatinny at the top front for buis)?

I want to put a vote in for a 13.5" model. 12" and 13" are too small. 15" is too big. 13.5 is juuuust right. Plus then I can do a FSB cut-out and still have room for a x300/tlr1 in front of the front sight @12oclock.

I agree, we should totally throw out any quality so we can keep the rail as cheap as possible. Heaven forbid the rail be over $200 so the bottom feeders can pretend they will buy it.

BCM is known for making cheap worthless crap, so you should have no concerns at all when it comes to pricing. I'm guessing it should be under $99. :rolleyes:

If people don't understand the above as a sarcastic rant, at this point I really don't care. I'm tired of people cheerleading for the cheapest prices while demanding top of the line products.

Paul, sorry for ranting in your thread brother, but this stuff reminds me over and over of the people who buy buy airsoft parts and complain they don't fit their Olympic Arms carbines. You gear is squared away, and I know you will price is where it needs to be. God bless you for having more patience than me tonight. Every time a new product is talked about it is the price or delivery date that people start bitching about.

The shape of the key with the round hole in the rear is for the recoil locking lug. The mount interfaces in this hole with .010" clearance and the screws keep it tight against the rail. It's a well thought out design. We made a slight change to our mounts to allow them to fit fwd / rwd (Our Weapon Control for ex.) compared to Eric's initial design.

woah, I'm not too worried about this thread going downhill. I was just stating that the things I could see BCM offering over an NSR is lighter (don't really see how), skinnier, keymod all the way around and less expensive. People don't buy BCM anything to put on their olympic arms guns.

BCM puts things out at insanely low prices so if anyone could produce a rail on par with/better than the NSR at a cheaper price, bcm could.

Btw not everyone gets tons of gear for free stick :-).

While your here, what are your thoughts on the new Parallax Rail? I held one at a local store and was extremely impressed with it. Though surprised i had never heard of it. Saw you took some pictures of it so I was just curious on your impressions, seeing as how you've held more lightwieght rails than a catholic priest.

KeyMod is less expensive to manufacture than a typical 1913 rail of the same length / diameter / material. The caveat to this is receiver attachment device / method.

As for quality, BCM makes top-shelf kit, the KeyMod they are finalizing is no exception.

I noticed in a pic on another site what looked like anti-rotation tabs, which is a very nice feature if it makes to final production. Look forward to more details as they trickle out.

My thoughts exactly. The same crap happened in the Centurion CMR thread. Let the manufacturer set their prices and you can vote with your wallet.

I'm looking forward to seeing more information on the BCM keymod rail. The mounting points on the 45's really intrigue me. Depending on the barrel nut design, I may have found a keymod rail that actually interests me.

Does anyone know if there are other designs available currently with the 45 degree mounting points? The KAC & BCM prototypes are the only ones I've seen so far.

07-23-13, 13:11
FYI

LAV just posted the best pic of it so far on his facebook page. Also mentioned it's an aluminum/magnesium blend that is extremely lightweight.

You can see the anti rotation tabs (score). However, the method of attachment to the barrel nut is new to me. I don't know what i'm looking at. Maybe someone who knows more about proprietary barrel nuts/ff rails could shed some light. (I see a single screw up so high it looks like it should be hitting the gas tube.)Certainly looks nothing like centurian, NSR, or troy methods that i've seen.

Edit to add: I would post the pic or a link to it here, but I dont think that is kosher.

Oh give Keymod a chance. It's a much better system than attaching rail sections to slick hand guards just to attach something.

Granted most people aren't attaching anything to the sides or bottom anymore except for flashlights and the occasional handstop. Still a good idea, and I'm not a weight weenie.

It has an integrated QD mount, correct?

Don't forget about Counter-Recoil, which is actually worse, when it comes to a sharp impulse. Courter-Recoil breaks optics, not recoil. Also, the KeyMod interface and related accessories utilizes "both ends" of the slot to secure properly, combating either direction of recoil.

I am looking forward to this rail very much. I do own and love a 13.5" NSR, but am not a kool aid drinker. However, that is a VERY bold statement. There is only so much you can do with keymod IMHO. With the exception of the slots being on the 45's...how could it be anymore revolutionary than an NSR? Proprietary attatchment methods/barrel nuts are so individualized. Some will love it, some will hate it. I can see revolutionary keymod attatchments...but the rail itself? Bold. Very bold. What i would VERY much love to see is a octagon keymod rail with keymod holes on the top of the rail...not picatinny. Then you can add sections as you see fit. Small section if front for BUIS, etc. But the rail would be mostly round and even lighter.

Keep in mind we know very little about this rail right now. However we already know it has anti-rotation tabs, keypads on the 45's, aluminum magnesium mix (IE wikid light), and possibly built in QD's. Also you've got to realize that bcm has a knack for making good shit and selling it very inexpensively. So a rail that is lighter then NSR, built in qd's, anti-rotation tabs, key mods all around, for cheaper....just that alone is revolutionary dude.

not in my eyes. different, yes. improved upon, absolutely. i dont need built in qd. thats the point of keymod. you can put it where you want. but far from revolutionary enough to make statements such as that when there are already outstanding products on the market. that said, i cant wait to see and try one.

but like i said...an ocatagon keymod tube that is 100% end user customizable for accesories with a rock solid barrel nut and attatchment point. make it super tough and super light weight. to me, that is the ultimate in keymod and (in my eyes anyway) what keymod should be about. absolutey 100% customizable and configureable to user needs and minimalist. What I cant wait for is the flood of keymod accessories to start hitting the market. To me, that is much more needed than additional rails put out by every company. But I do realize a company would probably produce a rail before they start making accesories for it. just my $.02.

Steve S.
07-24-13, 01:46
I don't think NeoNean was being sarcastic. He brings up valid points.

I don't know that the rail is revolutionary though. VLTOR coming up with the concept (to my knowledge), VLTOR having the good foresight to share the specs with the industry, and Noveske coming out with an amazing initial offering - those things were revolutionary for the KeyMod and will be the pivotal moments if KeyMod continues to become the "next big thing".

But if BCM can offer their own version of a KeyMod rail that is lighter due to different materials while being just as durable (or more so), and possibly offer it at a lower price.... well, then Paul and Company just raised the bar further.

Taking a concept and making it better and / or cheaper without sacrificing durability, quality, or being domestically made is what pushes the market forward. There are some great rails on the market under $200, and its being mentioned by an SME that KeyMod is cheaper to produce. Therefore, a low price point seems entirely possible. I think it will be largely dependent on this new lighter weight metal belt used and how much the raw material costs in comparison to Aluminum.

Personally, I would wait for BCM to work through initial issues and release the product specs before weighing on how much their rail is better/equal/worse than Noveske's.

P.S. Noveske's description of Keymod development does not jive with what BCM rep has listed in this thread. But that may be a topic for another thread.

I'm not seeing how that is possible (based on the spec). You have a larger diameter (a keyhole), a chamfered nut fits within/thru that keyhole, slides forward into the keyway then gets tightened up. The chamfer of the stud locks onto the backside chamfer of the keyway (vs the keyhole) by way of tension.

I must be missing something, perhaps something on the accessory side.


Edit: I'm guessing Detail B is a requirement on all keymod accessories themselves (for the system to work fully) ?

I'm not seeing how that is possible (based on the spec). You have a larger diameter (a keyhole), a chamfered nut fits within/thru that keyhole, slides forward into the keyway then gets tightened up. The chamfer of the stud locks onto the backside chamfer of the keyway (vs the keyhole) by way of tension.

I must be missing something, perhaps something on the accessory side.


Edit: I'm guessing Detail B is a requirement on all keymod accessories themselves (for the system to work fully) ?

Correct, detail B shows the counter-recoil lug.

The chamfered nut in the chamfered slot gives a significant purchase to screw-attached items. The nut also acts as a recoil lug. When fired, the weapon moves to the 'rear', heavy accessories don't want to move to the rear, and thus are being shoved 'forward' on the rail. However, recoil forces build-up in relation to the acceleration of the projectile and aren't very 'sharp' impulses. They have a curve to them.

The larger thru-hole portion of the keymod acts as a passage for installation of the nut, but also acts as a counter-recoil feature. When the BCG slams shut, there is a sharp impulse wanting to drive the gun forward, and accessories 'to the rear'. Those accessories are typically also already moving rearward due to recoil - thus counter-recoil is both a greater force and a sharper one as well (as Mr. Kincel pointed out, it's counter recoil that kills optics).

The thru-hole portion is also conveniently sized to clear the nose of a QD sling swivel (actual required size would have only been ~.315"), but is not intended to be used as a socket. This is because the diameter is interrupted by the slot feature.

Guys I say lets just wait for the rail to be released. If the rail is priced over $200 who cares we all the know and trust the BCM quality. We know that Paul is not going to put out a poor product.

It is nearly impossible to have a rail made out of a Magnesium Alloy, that is lighter than the competition, has Distr/Dealer pricing levels and retail at $200 or below. So people can forget about that fantasyland!

Wow, didn't mean to start a shit storm. Wasn't trying to imply that the rail would sell for under 200. Just saying if they were some how able to do that they would dominate the market.

Also, wasn't trying to spread rumors about features just rebutting people saying they can't imagine how it could be revolutionary by listing some things bcm could easily be putting into the rail.

Both paul and LAV are pretty stoked about the rail so I am quite confident it will at least be extremely interesting. Has anyone ever seen LAV run a ff tube rail? I haven't, so I'm hoping this one is something special. Plus I'm in the market for a new rail.

P.S. Noveske's description of Keymod development does not jive with what BCM rep has listed in this thread. But that may be a topic for another thread.

Interesting. What is Noveske claiming about KeyMod that varies from VLTOR and BCM?





How is the "different" material lighter and how is it "different" from say, an aluminum alloy? What are some great rails on the market under $200?

It was mentioned in this thread that the new Magnesium-whatever is lighter than Aluminum Alloy. It's different, based on what's been stated, because its a different material that is lighter. If this is true (I've seen no reason to think its a lie) than it is an improvement over what's on the market.

Off the top of my head, the Troy TRX, the TRX Alpha / Bravo, the VTAC, the VTAC Alpha / Bravo, the Apex gator tube rail, and my personal favorite - the Midwest Gen 2 Super Slim are all tube style hand guards that come in around or under $200 while being quality choices. I'm sure I've missed a bunch.

I think Grant killed any hopes of the rail being under $200 though. Being a little familiar with how BCM actually leaves room for dealers to make money, and the fact it's made in the US... I'm perfectly fine with it being $200+. It was an arbitrary number being used by NeoNeanderthal anyways to make a point that BCM generally prices their stuff really competitively.

Anyone know more about the material being used? To me, that's the most interesting part about this rail system.

Reading too much into 'rep'. Sales rep or product rep is a specific meaning. Rep is just short for representative which any employee, including the owner, at BCM is.

The material type is very interesting. While magnesium alloys do not cost much more than aluminum, the special tooling and machining environments are more expensive. Another consideration is how they are going to finish it. Hard coat anodizing is off the list.

I'm really looking forward to seeing this new rail. Lighter is always better, as we've seen in the current trend of slimming down and shaving oz's from rails from all the major players. I have an NSR that I'm very impressed with. If this rail is in fact lighter, it could be the game changer, or definitely a close competitor to the NSR, and make other rails basically obsolete.

I don't think the other modular rails or even the lightweight quad rails (daniel defense) are going anywhere. Options are always nice, some will like the keymod, others won't. I myself am very interested in this rail, I can see myself buying a BCM with one of these. Definitely a bold move by BCM!

I use a troy alpha tube, with a mount and slot QD swivel, a magpul VFG directly mounted to the tube, and a jetbeam BC10 in a gear sector e series mount at 12. I don't use any additional rail sections. I can't claim to know enough about the weight to say it would be heavier or lighter than my current setup, but I'd assume heavier.

Assuming no weight savings and with the knowledge I have no problem removing my tube, why would something like this benefit me?

wilson1911
07-25-13, 11:13
I would like to say I am glad someone else is coming out with a keymod rail that will be quality. I have 1 15" and 3 13.5 " NSR rails atm. while I do love these rails and have them on all my guns. There are several improvements that can be made.

I have noticed that the top picatiny rail is slightly lower than the receiver portion on NSR's.

The plastic panels I do not like, but I use them.

The keymod attachments always need to have a long or short rail section for mods to be attached. Direct attachment is preferred. This will move the item closer to the rail and be more stream lined.

Barrel nut seems to always be tightened down to between 70-80 lbs. This is a little tight for my taste, but it works. I actually like the barrel nut, its clean and simple to put on.

After taking Costa's class, I can say the gun with a NSR points very well, as well as helping have good hand placement and retention.

I cannot say if lighter and smaller would be a positive note. This being due to the size of your hand. Bigger hands tend to wrap around the whole gun more, leaving you with less of a "meatyer" feeling. Guys with larger hands may want more diameter. This could possibly be from years of 1913 style rails. In essence, sometimes a bit more is better for guys with larger hands. I have short fingers, so the NSR, is the bomb imho. Its very clean and grippy.
I also have the KAC rubber thumb stop on top to allow me to have the same exact hand placement every time.

A new rail should be an evolution of the standard (NSR) since he came out with one first.
Let's not forget KAC is coming out with theirs soon (I hope) which looks very good also.
At class Costa had one with his attachments directly to it, this I liked. Rubber panels I liked also. I am not a Costa fanboy, but a KAC fan boy. Nothing shoots like them.

There will be minor differences is rails, but what I would like to see is someone create some cool mods to attach to the rail in a clean and efficient manner.

Thankyou :dance3:BCM for coming out with good products at fare prices. More products = a better choice for the consumer and better prices.

How do you say PWS and BCM make the Keymod rails, and some other people do as well, and fail to mention NOVESKE who were the first to use it on an AR platform? I shut it off after that.

The BCM rail looks good, but there aren't many ways to configure a Keymod so I think we will see a lot which look similar. The largest differences are going to be how wide a company goes and its attachment method.

To be really technical didnt VLTOR start the keymod? They had vis Prototypes before anyone I believe.

Noveske was just the first MFR to use VLTORS new goodies on the rifles they build.

That doesn't negate that I've known about the BCM Keymod rail for awhile. I consider Paul a friend and speak with him on a regular basis.

FWIW, as an NSR owner, I'm happy to see additional Keymod offerings such as this and the URX 4. More adoption means more accessories and more variety and more competition. It's all win.

FWIW, I agree with those who have posted they would like to see Keymod slots all the way around, with just a short bit of rail on the top at 12 o'clock. I run a X300U and BUIS at 12 o'clock and QD mounts and that's all. 5" of rail seems like it would be about perfect. Having built in QDs front and aft would be nice as well, but I understand opinion varies since you give up the more generic attachment point.

The trouble with an interrupted rail in the top of a hand guard is the gas tube (or piston for those of you with them).

The height of the upper doesn't allow for use of a 'standard' height pic-rail to be mounted at the 12 o'clock position without interfering with the gas tube. Thus the top accessory rails would become a proprietary component for that location only.

this makes perfect sense and i would assume in order to accomodate it would make the diameter of the tube quite large. that is the one thing the NSR has going for it. VERY slender. putting keymods on the 45's and keeping an extremely slender tube would seem next to impossible to me. you would have to open up the diameter to accomodate. but if it could be done...you would very much be on to something there.

1. A barrel nut that doesn't have to be timed with the handguard

2. An exterior anti-rotational tab

3. 45 degree mounts. *Remedied by BCM & KAC

4. FSB cut out versions (please)

5. Many may want a heat shield. Not an issue for me

Thinking....

Besides those things I can't recall another improvement for my purposes. I could complain about a lack of a direct mount vert grip and similar other items but I am certain these are in the pipeline. Its just the industry catching up with this relatively new mounting method. Looking forward to the future.

I agree, we should totally throw out any quality so we can keep the rail as cheap as possible. Heaven forbid the rail be over $200 so the bottom feeders can pretend they will buy it.

BCM is known for making cheap worthless crap, so you should have no concerns at all when it comes to pricing. I'm guessing it should be under $99. :rolleyes:

If people don't understand the above as a sarcastic rant, at this point I really don't care. I'm tired of people cheerleading for the cheapest prices while demanding top of the line products.

Paul, sorry for ranting in your thread brother, but this stuff reminds me over and over of the people who buy buy airsoft parts and complain they don't fit their Olympic Arms carbines.

A handguard is a piece of aluminum. There is no reason to charge 300-400 dollars for one no matter who made it.

I do not skimp on parts for the rifles I have built. Having said that, I would never pay more than 200 for a handguard so I can see where he is coming from.

You are not paying for a just a piece of aluminum. Don't forget to tally on marketing, R&D, quality control ect..

Interesting perspective. Do you even have a clue what it takes to make a rail?

The cost of aluminum, CNC machines that have to be bought and paid for, employees, electricity, insurance, etc... etc...

Having worked for 1 firearms manufacturer for 3 years and currently working for another one, I think I have a pretty good idea of what goes into making parts.

After all that, it is still just a piece of aluminum. There are far more machining processes needed to machine a lower and those are only 90 bucks. Handguard prices are so high because people will pay it.

I'd like to learn more about the magnesium alloy that is being used for this product. I have gathered it is lighter than the aluminum offerings. How does it compare in the area of strength?

From what I have been able to find on the internet, it sounds like these magnesium alloys are a relatively newer technology and that significant obstacles had to be addressed before it became viable.

Obviously BCM has not told us exactly what material will be used to make this product, but what do others know about magnesium alloys in this type of application?

seems like a terrible analogy to me, and a terrible way to introduce yourself to a couple of the most knowledgeable members of this forum (stick and Iraq have been contributing longer than you've worked for your "1 firearms manufacturer" whatever that means).

you're not just paying for the material, you're paying for the time, research, testing, and engineering that went into developing a NEW product, not some lower receiver that has been produced the same way for decades.

Designing a handguard isn't like inventing the jet engine. It's a piece of metal, usually aluminum, that is machined into a shape. Does it really need to be 3-400 dollars? How many R&D hours could possibly justify a 400 dollar tube shaped piece of metal?

This is by no means a knock on BCM, I'm sure their product will be as great as all their other parts. My comments are about free float handguards in general. How revolutionary can a tube of metal be to justify a 3-400 price tag?

ETA: To those of you that work for BCM posting here and the OP, I'm sorry if my comments are derailing this thread about what will undoubtedly be another amazing BCM product.

No, because it takes a ton more R&D to design a firearm with moving parts than it does to design a tube of metal.

If you guys want to continue paying absurd amounts of money for a tube, more power to you.

Out of respect for BCM, I'm done posting in this thread. I will say one thing before I go. I hope BCM can keep this product in the 200 dollar range too.

I think i should apologize here as somehow i started this shit storm. All i meant to say was that BCM has a knack for taking expensive concepts/products and making them available for less (battle comp vs bcm comp). And that if they could do that with this rail (NSR vs bcm rail) they would DOMINATE the market. This was a response to a person who commented that they could not see any possible way for this rail to be revolutionary.

I wasn't trying to say a highly engineered rail isn't worth 300/350, or that bcm was ripping anyone off (i had/have no clue what price this rail will be at). I didn't mean for all the olympic arms, WW, Bushy, DPMS, Stag "your just paying for the name" bandwagon to come out of the woodwork and jump in the boat with me.

***With that being said. I do have confidence that whatever price BCM sets for this rail will be extremely fair. I cannot think of ONE example of an OVERPRICED piece of gear that BCM makes. My point was that it their price for the rail could be revolutionary, just as it is for their uppers. For F*cks sake they sell their upped for 450 bucks. You can buy an upper, bcg and blem lower making a great gun for 1k!****

I have no doubt that BCM's pricing will be competitive AND fair. It's not our place to tell them what we think is fair. Quite frankly, it is ridiculous to me that We, the membership of M4C have allowed this thread to evolve as it has. You should know better and behave according to the standards of M4C. IMO, the mods have been extremely gracious in allowing this to go on as long as it has. We all know the rules here and if you don't, you should not type one single more syllable until you do. (Neo, this isn't directed at you specifically)

Regarding the rail, I'm keenly interested in it and looking forward to official release details. Unfortunately, people just want to talk out of their rear ends in the absence of facts just because they have time on their hands and think their opinions should direct how a company develops a product and how they should do business. I think BCM is keenly aware of what their target customer base wants and needs, as shown time and time again by what products they bring to market. They have high quality standards and do not produce poorly conceived products. Let's just cut out all this speculative, self-important BS and wait to see what they have actually come up with.

Not trying to throw you under the bus but the thing is I never said that. The comment i made that started the shit storm was:

"Oh don't forget cost. If they can sell this rail for under $200 they will clean house. They made a comp that rivals the battlecomp for 40% less $."

I shouldn't have said that, obviously it is incredibly difficult to make a great rail for under 200$, it was jut an arbitrary number I threw out there because nsr keymods are going for 250 right now. And bcm always seems able to produce products as a lower price than novekse. I never said rail prices are out of control, or that companies are ripping us off on them. I just bought an NSR for 255 bucks and felt it was a great deal because i couldn't wait for the BCM rail.

You misunderstood NeoNanderthal (as did some others) - so your "defending him" is irrelevant to the conversation. Again, he used an arbitrary number to make a point about BCM's very competitive pricing structure. A lot of people seemed to have missed the point - he wasn't complaining about rails over $200.





I'm in the wrong biz, apparently. I guess in order to be taken seriously around here, you either need to be a factory certified armorer (repair man) or a photographer.

I'm going to risk an infraction here by not letting this comment slide, but someone needs to say something.

You better check your fire. IraqGunz and Stickman are much more than a "repair man" and a "photographer". Both are well known and respected in the industry. Both have also risked life and limb serving this country to protect the right of someone like yourself to talk shit on an Internet forum about them. On behalf of all of M4C ... PLEASE stop exercising this right.

You worked for a firearm manufacturer - we get it, we got the memo. Keep in mind that the business practices, pricing, and margins are very different between a large firearm manufacturer and the smaller ones.

You are one among millions involved in this industry. Does working in the industry demand some sort of respect? No. It will get you taken a bit more serious if you're kind, courteous, and add to the knowledge base of this forum.

Making personal insults against those who have earned the respect of the industry and its customers, simply because no one has responded positively to your complaining about current rail pricing structures, isn't going to get you that same level of respect. Simply proclaiming having had worked in the industry isn't going to magically make your opinion more valuable here either.

I'm sure I have some insults coming as well now - that's fine, doesn't bother me. What does bother me is insulting those who have paid their patriotic dues because of your inner ego issues.

That's 7.7 oz for the BCM-KMR-13 rail, which is the complete weight (with all mounting items, including barrel nut).

The bare BCM-KMR-13 weighs 5.5oz and is long enough to cover the gas block of a rifle length gas tube (approximately 13").

The bare BCM-KM-10 (10" variant which will cover the gas block of a mid-length gas tube) weighs approximately 4.3oz for a total assembly weight of 6.5oz.

PLEASE consider doing a .308 rail, preferably DPMS! The lightest rail I know of for a .308 AR is the Troy slick rail, and at 13.8" it's about 13oz including nut.

For people trying to get the lightest rail they can on a .308 AR, the Troy's the only real option we have at the moment. So if something comes along that's 5oz lighter than the current lightest rail, then pretty much there'll only be one acceptable choice if you're looking for a lightweight rail without giving up any features/functionality.

How do you say PWS and BCM make the Keymod rails, and some other people do as well, and fail to mention NOVESKE who were the first to use it on an AR platform? I shut it off after that.

The BCM rail looks good, but there aren't many ways to configure a Keymod so I think we will see a lot which look similar. The largest differences are going to be how wide a company goes and its attachment method.

I am way late on this but this is the first time I watched that vid and that is exactly what i did when he was going through that list. The entire time after that i was just like, I think you missed one man :mad: hah.

Not BCM. Just the certain people who cry about the price of gear.

BCM used to be bushmaster prices. Thats how they became who they are.

Remember the old addage, why pay DPMS or Bushmaster or RRA prices when you can have BCM for the same or just a tad more.

50% + or more in price is not a tad.

If Fortis can make a Keymod FFL rail that starts around $160 and goes up to around $240, Then I'm sure BCM with its much larger scale can do it.

Perhaps I'm missing something about the design ........ wouldn't it be better for the smaller diameter to be rearward?

Or do accessories want to move forward under recoil?

the accessories will want to move forward under recoil because the rifle is jolting backwards with every shot.

Agreed! A lightweight, slim rail option for the .308 AR types would be great.
But Troy is not the only option. Both JP and Apex both have rails for 308 AR's, in either Armalite or DPMS patterns, and the Apex ones come in both low and high profile for the top rail.




PLEASE consider doing a .308 rail, preferably DPMS! The lightest rail I know of for a .308 AR is the Troy slick rail, and at 13.8" it's about 13oz including nut.

For people trying to get the lightest rail they can on a .308 AR, the Troy's the only real option we have at the moment. So if something comes along that's 5oz lighter than the current lightest rail, then pretty much there'll only be one acceptable choice if you're looking for a lightweight rail without giving up any features/functionality.

I like the rotation limiting tabs.

As an aside on the EAG picture: I've seen nose-to-charging-handle shooting before but not cheek-to-charging-handle. :eek:
I know it's Pat Rogers, and thus am sure he knows what he's doing and it works for him, but it is unique, IMHO.

On the rail, I am interested to know what the protruding tab or knob is that is just below the top rail and close to the receiver.

Furthermore, the forward grip is probably a chopped down BCM VFG, but might it be a new shorter version of the BCM VFG, one that is the same length as the Magpul RFG?

This rail looks light as a ghost's pajamas and something that's going on my wish-list for darn sure.

Good eye, I didn't even see that. Obviously complete speculation but that tab looks integrated and part of the rail, and it looks like a keymod slot but going in the opposite direction compared to the rest of the rail...maybe BCM figured out how to torque down the rail to the barrel nut but via integrated keymod:meeting:, more likely I'm just speaking out of my rear though

I'm probably asking too much, but oh how I hope these use a standard GI barrel nut. From the profile of the rail, and what I can see of the mounting method it seems as if they have a proprietary barrel nut.

I would doubt that. Timing of a GT results in over torquing (or excessive torque) on the barrel nut. I think that ship has sailed with current state of the art rail designers.

I suspect a mag alloy exists that will be durable enough to make a rail out of. Mag alloys are used in alot of everyday items that require strength and durability.

Rails don't go through 1/10th of the forces, streses, and loads that any of those products do.

Using some new alloy and jacking the price up, is a waste of money, IMO. Unless it shaves off like 6-8oz, there is no value in it.

Goes right up there with CHF barrels, and all the idiot masses who eat that shit up like its some kind of superior method of barrel creation (when in fact, its the cheapest).

When normal rails start breaking from the abuse (DD, Noveske, Larue,ect), let me know. I have yet to see it.

So your saying the new BCM rail would definetly be worth it no matter the price comsidering a larue 13.2" rail is 17.8oz and the BCM 13" has been mentioned here to possibly be 7.7oz? That's way over your arbitrary 6-8oz reduction.

My point was that an alloy exists that will easily serve as a material to manufacture a durable rail from. The poster I quoted expressed concerns that a magnesium alloy would lack durability.


Goes right up there with CHF barrels, and all the idiot masses who eat that shit up like its some kind of superior method of barrel creation (when in fact, its the cheapest).

The process reportedly creates a more durable barrel but really is over-rated IMO. A quality honed button rifled barrel is as accurate as any CHF barrel from what I have seen. As far as "the masses" are concerned.. its the same mentality as paying twice the price for a rollmark ... or worshiping a weapon platform.

Anyhow different subjects for a different thread.... lets try to stay on topic

Magnesium is very, very light.

Pure aluminum weighs 2712 kg per cubic meter.
6061 aluminum weighs 2720 kg per cubic meter.
7075 aluminum weighs 2800 kg per cubic meter.
Pure magnesium weighs 1738 kg per cubic meter.

Magnesium is roughly thirty six percent lighter by volume than aluminum. 473 degrees celsius to ignite Mg ribbon...much higher for larger samples. In fact it has been used in high performance engines for a long time.

I'm not really on the keymod bandwagon, but Mg alloys are a damn good choice for rails.


The process reportedly creates a more durable barrel but really is over-rated IMO.

Just a note, it's not "reportedly." The science is there, hammer forged barrels are in fact more durable. It's not up for debate...forging has been proven to provide the benefits claimed. The fact that the barrels are produced faster, more consistently, and more inexpensively(if you don't count the cost of the forge,) are icing on the cake. What can be debated is whether or not it matters to 99% of shooters...of course it probably does not.

Just a missed opportunity with some bad fleas.

First is the price. Its $450 more than a PRO but offers the same battery life and a .25moa smaller dot.

The solar panel does not power the optic if the battery is dead, it only works if the battery dies while in the sun. This was a huge missed opportunity and really came out with me questioning why is it even there if it only works when you have a good battery.

There is a horrible reflection from the diode set in the optic that completely blocks your target and minimizes the dot enough that you cannot see it.

Its heavier than other optics.

The only pros imo was the large FOV and the Bobro mount.

You got something to say?
