NEW: Centurion Arms Free Float Rail System...

[grinch]

I look forward to getting the FSP models out myself I think they will land on a few of my guns themselves.

[Biggy]

A mid-length FSP model with a low profile bottom rail would be really nice .

A mid-length FSP model with a low profile bottom rail would be really nice .

Lo-pro bottom rails don't really workout with FSP if your using a lo pro bottom rail you should be using a lo pro gas block so no FSP needed just get a longer rail.

[Magsz]

Just chiming in to say that the midlength FSP models are drool worthy.

Looking forward to seeing these!

As soon as we get one other project off our plate we will return to the rails and the the FSP done it is my next priority project.

I have tryed to put in request for the 12" rail system on the Centurion site but was unable to sign in. If I could sign for that request now I would like to be one of the new owners of this great looking FF Rail system.
thanks

I sent you a PM you need to E-mail me on my website so I can get you with my web guy to sort it out.

Thanks

[zukiii]

any updates? i have a patrol rifle school coming up in december and i need your 9in rail to complete my build.

thanks..

[grinch]

Ok sorry for the delays guys I based what i was telling people on the info I got from the machine shop. It was wrong real wrong. The 7in were the first to roll out they are off the machines and still being deburred when that is done they will go to anodize and get laser engraved then ship. I would like to say that will be next week. Then the 9in rails are up for production I hope they are ready to ship by jan 1 but who knows.

NOW on the bright side the rails look GREAT!! I'm VERY please with the way they are turning out. They are extremely light weight and we should be the lights rail on a standard barrel nut once installed. Also much more rigid then most and we now have a patent pending on the rail:D

[rob_s]

Thanks for the update Monty.

[cdmiller]

Monty,

I've been through the entire thread and can't find an answer to any of the questions about compatibility with the Adams Arms (or any orther) piston kit. Can you please address this question?

Thanks,
cdmiller

PS - I tried to email you through your website twice but both times the page crapped out when I hit the "Submit" button.

[outrider627]

Can we pre-order the Mid length FSP rail pictured earlier in the thread?

[grinch]

I'm looking into the Adams arms thing right now will keep you posted hope to know by the end of the week.

Right now there is no pre-order for the FSP.

Thanks
Monty

These are pictures to give you an idea on the weight of the Centurion Arms carbine length free float rail system. Comparing it to an all plastic Magpul MOE handguard with all the necessary hardware, you will find the Centurion Arms carbine length rail are just slightly heavier to the MOE assembly and if you add a rail to the MOE the weight of the MOE becomes heavier than the Centurion Carbine length free float rail.

http://photos.imageevent.com/smglee/ca/huge/P1030353.JPG
Centurion Arms rail with all the hardware minus the barrel nut at 8.5oz, this set up is only .5oz heavier than a all plastic handguard set up.

http://photos.imageevent.com/smglee/ca/huge/CA-Rail-weight-1.jpg
MOE handguard with all the hardware minus the barrel nut, weights in at 8oz

http://photos.imageevent.com/smglee/ca/huge/CA-Rail-weight-2.jpg
MOE handguard with all the hardware plus a rail section, minus the barrel nut. weights in at 9.1oz, that is an amazing .6oz heavier than the CA rail.

also added are a few pictures hot off the press on Centurion Arms 12inch rail on a 16" hammer forged barreled upper.

[Frens]

maybe I missed the answer in this thread but..
are these HGs round like the KAC RAS or oval like the DD Omega?

thanks

[Mark71]

Thanks for the pics Lee. That rail looks great. How much does it weight?

[scottryan]

What are the width and height of these rails?

[SMGLee]

Narrower than a RAS, but not as slim as the DD Lite rail.

Eyeball with a ruler, the rail is 2-1/8" wide, and 17oz with the extended barrel nut, so with a standard barrel nut, the rail should be under one pound (16oz)

[RAM Engineer]

OBE - see below.

[RAM Engineer]

The rails are 2.1in wide and 2.375in tall we plan at a later date to do one that will will have a lower profile bottom rail but this one was set to be able to do front sight post cut outs so the bottom rail needed to be this low.

Just found this back in the thread.

[lmichel75]

any time frame for a release date? i'm thinkin it will not be on time for christmas this year... :sarcastic:

Manufacturing is an ugly thing at times. Everything from changing material costs, broken machines, or anodizing mistakes can throw time tables out the window. I know that Monty wanted these out by now, but sometimes things are outside of his control.

Hopefully its soon.

[zukiii]

are the 9in rails still scheduled fo release in janurary??

[bigez1]

When I preordered the 7" rails at the beginning of Sept they said 6 weeks. 10 weeks later in med November Monty told me 2 weeks. 4 weeks later on December 11 he told me "late next week. Almost 3 weeks later I haven't heard anythings else. I am going to give it another week then I am going to purchase something else.

[buckshot1220]

Just got my order in for the 7" rail! Can't wait to install it and will report back with initial impressions.

Let's get workin' on the 10"/12" models now Monty!!!:D

[11B101ABN]

Sweet!!!!

Looking forward to the 12" rail. Looking real good.

[Texshot]

Just got my c4 7" rail delivered. I'll post pics of it after the install when I get home ... stupid job keeping me from upgrading my AR!

[grinch]

Sounds like guys are already getting them that was pretty fast. The 7in and 9in rails are now shipping the 10's will be close behind.

I'd love to see the pics of the rifles you guys are putting them on.

Thanks
Monty

[M4Fundi]

Thats Awesome!

[zukiii]

9in rails are shipping?? Im on the list but I haven't received any email with the promo code.

[rob_s]

Remember to add ~2oz. for the stock nut which remains when comparing to other rails/tubes where the proprietary nut is included.

[zukiii]

Rob.. What's your initial impression of the rail??

[rob_s]

Appears well-made, well-rounded, etc. I was actually supposed to receive a 9.0 for T&E so I don't want to muck this one up too much. Once I get the 9.0 installed I'll have more feedback.

Well, it took an hour or two, but here she is! It would have been VERY nice to have a set of directions for removing the stock components, but a little "Um, what's this and how did they intend it to fit like that" I was able to get a shockingly well engineered fit...this thing could hold up Donald Trump's ego.


I am NOT an AR pro and have not done advanced disassembly, that being said, install issues were few but critical ...

1. Removal of the Delta ring needs to be addressed in supplied directions (no instructions came with my rail)...I followed the steps shown earlier in this thread on cutting the ring off with a dremel, I had to use a hacksaw, my dremel was on the fritz. Go slow and it's cake. WRAP YOUR GUN UP TO AVOID METAL SHAVINGS!!!! REMEDY - Supply INSTRUCTIONS

2. Removal of the handguard brace plate that hugs the front sight (gas tube goes through this and into the FS) - I ended up un-pinning the FS, sliding it forward and sliding the brace plate off the end of the gas tube in the direction of the receiver, then cutting it where I had to get it off the barrel. REMEDY - Supply INSTRUCTIONS

3. I have four full sets of allen/hex tools and none of them worked for the supplied C4 rail screws, I spent about an hour digging around my shop and FINALLY found one that fit perfectly. REMEDY - supply the two needed tools, or LIST the ones I'll need.

Overall I am satisfied, quality is life stakingly good, weight is acceptable, fit and rigidity would make NASA on a $100 trillion budget drool with envy.

Looks like all the edges are nicely deburred and the edges of the slots are nicely scalloped ala DD. I always liked that added attention to detail. These look great.

[ncturkey]

Videos are gone. I would love to have seen them. Why did you remove them?
This is NOT a scientific test, but interesting none the less......

After a 210 rounds full auto dump, I stood on the forward grip to see if I can make the rail itself rotate off its centering tabs. you can actually see the VFG start to bend after I started to apply pressure to it.

here is the video posted on youtube.

Nice looking rifle Stickman. If I got the 9" CA Rail I remove the FSP and have just a gas block. Is that Knights Armorment rail covers the way a lot of folks are going. I have the ladder rail covers on my handguard. What kind of gas block is that? Thanks

Its a Daniel Defense setscrew gasblock, its not my favorite, but its all I had available for this picture. Typically I would not run an exposed low profile gasblock, especially if it were not pinned.

[jvencius]

Hopefully shortly after SHOT!

Cool--that's not too far off. I'm waiting on a DMR upper with the 12" Centurion rail (Monty said in an email that I was one of the first to order a full build with the in-house rail) but I'd rather keep waiting and get a system that meets Monty's specs than have him hurry the production schedule and let a sub-par product out the door.

[ncturkey]

Ya i like a pinned gas block. I am thinking of build a rifle with a carbine gas system with the 10" CA Rail. If they make it so I can use a low profile gas block.

[jvencius]

With a 16" barrel?

I was wondering the same thing--with a low-pro gas block under a rail I cannot see any advantage to a carbine gas system vs. a midlength system...

[9111B]

I am going to order the 7 inch when I get paid tommorow.

Is there going to be a problem with the hanguard cap and the 7 inch rail on a carbine length gas system?

[Spoon]

lethal dose and Frens- I think this will be the very next version we do right after we run the batch of 7,9,10, and 12in rails. In fact the plan is to save some of the first batches material to make these so once we get the pre orders filled we will do a FSP carbine and mid length.

Glad you guys are liking it

Just FYI on the sling cups we are planning on doing the front and rear on both sides for the 9, 10, and 12in BUT not for the 7in we feel this begins to take up to much rail space. So the 7in will only have them in the rear.

Oh yea I don't mind the photo shop at all glad you did it thank you.

Thanks
Monty

Will the FSP carbine models be able to be installed on a pinned upper? If so where can I pre-order!

I meant more along the lines of that I would try to find a picture for him, though I do like a midlength better than a carbine gas system myself.

[zukiii]

just curious.. did you guys receive a tracking number when your rail was shipped? i placed my order on the 8th and i still havent received a tracking number yet..:(

[ncturkey]

Yes I would proabbly use a 16" barrel with a 10" rail. If I choose 18" or 20" barrel I would choose a 12" rail. It really depends on what I plan on doing with the rifle. I am not compentition. or military shooter. The 16" would be for a range rifle and 18" or 20" where be a varmint rifle. I may even try a mid-length gas system. I have heard mid-length gas system are good to use.

@zukii - I did not get a UPS tracking #, it was delivered via USPS, their tracking is not exactly impressive, by the time I decided to check on it however it was delivered, 3-4 maybe.

I would take a hard look at trying out a mid length, there are too many benefits to ignore. I'll find a picture and get it posted shortly.

The pics of the carbine rail have the factory barrel nut showing through.
The rifle length rail is supposed to come with a proprietary barrel nut, right? What is that going to consist of and look like?

hey Stick, your photo shows a lot of surface granularity on the rail similar to the finish of the Mbus.

is this how it is, or is this a photo effect?

very nice photography, btw. I always wanted to tell you that... :cool:

Thank you for the compliment.

The image is shot to show the rail very close up, its also shot with heavy side lighting, which exaggerates texture. I feel pretty confident in saying that if the overall machine and finish work is not the best I've ever seen on a rail, its got to be one of the best. I have several different rails sitting next to me, so its not a sample of one, though I admit it is a sample of a limited amount of C4 rails in the big picture.

[Stickman]

ra2bach,


In the below picture, the lighting is similar, though varied by a few degrees, and you can see that the upper receiver and rail are similar in texture.

pics soon to follow!!

[Waylander]

If you've handled one of these rails, how does it compare to a Troy or Daniel Defense? I would hope the finish, geometry, and weight is better than a Troy and near that of a DD rail.

Weights are already posted, but I would put the machine work against any of the top name rails out there. Its at least as good.

The one I have does not.

[decodeddiesel]

Well, I just ordered a 7" model for my LMT 10.5". I really hope it has the KAC cutouts as I will be using stippled KAC panels with the rail. I really hope it is shipped soon!

you base this hope on what? It is contrary to all of the evidence presented to you in this thread. IIRC at least three I'd us have told you that the 7.0 does not have the cutouts.

[9111B]

Perhaps this is why he hopes there will be cutouts for the KAC Panels?


There will be a few changes for the production rail it will have Q.D. sling swivels on each side andthe rail cut outs in the front to allow the use of the knights rail panels.

[decodeddiesel]

Dude, calm down. There really is no need to take a tone like that with me.

I asked the question a long time ago in this thread and Monty answered that they would have cuts. I based this "hope" on this information. I simply missed the KAC slot discussion that had been happening recently on the last few pages of the thread until after my order had been placed. I canceled my order with Monty.

[R0N]

does your 7'' C4 has the cuts for KAC panels?

It has the QR sling mounts, but I don't think it has notches to lock in the KAC rail covers.

The KAC rail covers are so tight on it, I don't think they will move though.

[orlanger]

Received my 9" rail today. Took about an hour and a half to remove the delta ring assembly and handguard cap then install the new rail. I installed it on my BCM standard 14.5" mid-length upper with a pinned Battlecomp 1.5.

Initial impressions are on par with everyone else. Appears very well machined and thought out design. Once installed it locked up tight with no noticeable play whatsoever. Time will tell how well it holds up but I don't foresee any issues. Overall I'm very pleased.:)

FWIW, XTM panels fit no problem.

Your post wasn't clear. It sounded like you read the entire thread, saw the pictures posted and the discussion on the topic of the notches on the 7.0 rail, and in spite of all that ordered a product that all indications were didn't fit your needs/wants/desires/wishes. I simply wondered if you had information that wasn't available in this thread that the production models had changed. I *think* the rails I got are production but your post made me wonder.

There is no "tone" or lack of calm. Right back atcha bunky. :haha:

[EzGoingKev]

you base this hope on what?

Maybe on the fact that having them is the industry standard?

OK. So I am really late to the party. Have been looking at FF rails and was debating between DD Omega and the new Samson Evolution.

This particular build has a pinned flash hider, which is why I am somewhat limited. I am wanting to run a 12 inch rail. I was excited to find this since it uses your existing barrel nut. But after going to their website I see that they recommend using their extended barrel nut for lengths over 9". Has anyone used the 12" and not used the extended barrel nut. Says on the website it's needed for hard use.

This will be for range and fun. Not knocking down doors. But I don't want it if it's weak enough that if I were to drop it on the rail or push on it a bit, it pivots on the barrel nut.

If I decide to go full rails, and cannot change the barrel nut, am I better off with the Omega?

Thanks guys.

[zukiii]

if you have the means to take off the flash hider/muzzle device and remove the fsb from your rifle i would go with the centurion rail. i have had an omega in the past and its a good rail but i think i prefer monty's rail system.

also.. if an extended barrel nut is recommeded for the rifle length rail i would go with it rather than keeping the original. better safe than sorry.

[decodeddiesel]

Your post wasn't clear. It sounded like you read the entire thread, saw the pictures posted and the discussion on the topic of the notches on the 7.0 rail, and in spite of all that ordered a product that all indications were didn't fit your needs/wants/desires/wishes. I simply wondered if you had information that wasn't available in this thread that the production models had changed. I *think* the rails I got are production but your post made me wonder.

There is no "tone" or lack of calm. Right back atcha bunky. :haha:

Got it.

Let's back up a second.

If I understand you correctly you currently have a barrel with a pinned flash hider and, presumably, a full front sight base? Or do you have some kind of low-profile gas block? and if so which one? Tell us a little more about your rifle as I'm not sure what you're wanting to do will work anyway.

To install the Centurion rail, assuming you have the gas block worked out, you'll need to cut off the handguard cap and the delta ring.

[nickdrak]

I am planning a new build using a Centurion 16" LW middy barrel with a fixed FSB and the new Centurion C4 9" handguard. Cant wait to get it finished....

[Stickman]

Has anyone used the 12" and not used the extended barrel nut.




I've used it, and I don't think its needed even for hard use.

[Waylander]

I agree. Several manufacturers use the factory barrel nut on some extended rails. Daniel Defense, Troy, Samson, MI, all come to mind.
Correct me if I'm wrong but haven't there been some issues with aftermarket barrel nut steel being weak? I'm not saying that's the case with the CA barrel nut.

[zukiii]

since the extended nut comes with the rail and the guy who manufactures the rail suggests using it.. why not?

[Waylander]

since the extended nut comes with the rail and the guy who manufactures the rail suggests using it.. why not?

Because I may not want or feel the need to remove my barrel nut when four other manufacturers use the factory nut.

It has a full FSB and pinned flash hider. The Roto-Zip followed up by the dremel will have the FSB and handguard cap down to size in about ten minutes. Have done this a few times. Example:

http://i35.photobucket.com/albums/d155/twpayne75/STAGCOMP016.jpg

Basicly was just curious about the MFG wanting you to use the extended barrel nut considering I cannot remove mine. Have never used longer than a ten inch rail. Did not know if the twelve inch had that much more leverage.

[twpayne75]

Because I may not want or feel the need to remove my barrel nut when four other manufacturers use the factory nut.

And in my case I cannot remove it without unpinning the barrel. Which i am really not interested in doing.

Thank you for the info Stick and Sqwerl. I will take your word for it and try one out. By the way Stick, I killed the better part of yesterday going through your Flickr account. Those pictures just make you feel warm all over. :thank_you2:

[Waylander]

According to the CA site the 7" pre-order codes have been sent but it looks like the status on the rest of the rails hasn't been updated lately. Has anyone that ordered the 9" done so with a pre-order code? I submitted for a 12" pre-order code and I'm trying to get a general time frame of when I may receive it. It just seems a little backwards to me to already have the 10 and 12 for sale when the codes haven't been sent out but I may not be fully understanding how this works.

[Stickman]

since the extended nut comes with the rail and the guy who manufactures the rail suggests using it.. why not?

Personally speaking, its because of my experience with assorted similar equipment, experience with the 12" Centurion Arms rail, various armorer training, personal real world and training use, and last but certainly not least, my multiple long conversions with Monty about the subject.

While my conversations with Monty are not going to be quoted here, I will say that I would not make my recommendation if there was conflict from him regarding this topic.



ETA- I don't think the special barrel nut is coming with the 12" rail, I believe it will be an optional piece down the road.

This is good news. If the stock barrel nut can be used with the 12" rail, I can just install it myself. The rifle is my on-going project, so the more I can do myself, the better. Cheaper too. :D

I just want to confirm, are the 9" rails available to ship now? Thanks.

Stay safe,

http://www.pbase.com/image/131900419.jpg

I played with one of the first production rails, and I am in love. I was a big fan of the Omega rails before this, but these rails have an even better design and are of lighter weight.

E-mailed Monty today, and it looks like mid-lengths are sold out for now.

Also, I confirmed that future batches of these rails will indeed have KAC rail panel cut outs... the machinist just forgot them with this batch.

[stevie]

The 9 inch rail that I ordered last week shipped yesterday.

[Waylander]

Any ETA or updates on 10" or 12" rails?

[nickdrak]

I need to order a new 16" LW Middy upper in the next few days. Im hoping I can get one of yours with a fixed FSB and either a 9" or the FSB cut-out version C4 rail pictured below. Inquiry email sent thru your site.

[grinch]

Ok sorry for the delay on getting to this guys been wrapped up for the last two weeks.

Updates are-

7in and 9in are shipping

10in are coming off the machines now and should be start being ready to ship the middle of this week.

12in are getting started now so give them 2-3 weeks.

Changes- we no longer are going to bother with the extended barrel nut being recommended for the 10 an 12in rails. We started that due to the fact we felt the rigidity of some of the other rails on that market that attached to the standard barrel nut were unacceptable. We knew ours would get better results with it being 2 pieces and with our patent pend different lock up method but were still very skeptical it could be done on such a small purchase are of the standard barrel nut. Well we mounted some 12in rails on regular barrel nuts and after twisting, yanking and some abusive use meant to tweak it we were pleasantly surprised how rigid it turned out to be. We fell that the extended barrel nut is really not needed but since we have a batch of 100 plus made up we will offer it as an option at an additional cost for those who want it and are building from scratch.

Also right now only we 7in rails are missing the KAC cut out and when we are out of these the next batch will have them.

Thanks
Monty

Hi Monty and thanks for the updates.
Will an extended barrel nut be available for purchase with the rail if desired?

[grinch]

Yup we will keep some around as an option.

well shit monty now i have to have a new upper, lol. i think a 12" 300 blackout is in my future

[m1a_scoutguy]

Yea,,I have a 10 on Order !!!:D:D:D:D They sure look awesome !! It will be another reason to build another rifle,,and whats wrong with that,,LOL !!!!

Sounds good I cant wait to do a 300BLK myself I've built a few whispers over the years for guys and have one for myself I never got to finish so I may switch to this and get a batch of barrels done.

[nickdrak]

Monty,

Got your email, thanks! Just for clarification, are the 10" rails that you plan to have ready next week the FSB cut-out version pictured below? If not, any ETA on those?

Monty, I held off on buying the 9" with my pre-order code because I realized I really want to go with the middy FSP cut out model. Is ther any chance I could get a pre-order code with for the FSP model? I totally underestand if I missed the boat on this, just giving it a shot :D

[grinch]

Joe,

I know the developer of the 300BLK we spoke a few time while he was developing it I have always liked the idea. He mentioned I should carry it and i agree BUT as with anything projects need to unfold one at a time. Right now my focus is getting the rails going and production flowing smoothly then to the next project.

I did not do a pre order for the FSP rails and at this point have no plans to do it. We will post on this thread and on our website when they are available.

Thanks
Monty

The FSB must be removed to remove the handguard cap so this point of yours is moot.

This is the one thing I'm still curious about. How did you get the handguard cap off short of depinning the FSB?

[CaptainDooley]

More a theoretical question than whether or not you plan to make one in this series - but is it possible to do a 12" (or even 13") with a FSP cutout for a middy that has more top rail in front of the sight or is there just not enough room?

[rob_s]

This is the one thing I'm still curious about. How did you get the handguard cap off short of depinning the FSB?

Proper application of various cutting tools will work to remove the cap.

[Stickman]

Dremel, shears, hacksaw etc..

[5shot]

YUP! its coming. :D

Do you have a price set for the 12" FSP Version? Can we pre-order?

[grinch]

Sorry no pre-order on anymore of the rails that was a pre production deal we offered and now they are in production. It really was a risk free deal we did not take money up front just confirmed a lower initial purchase price.

We do not have a set price yet on the 12in FSP yet but best guess it will be close to the regular 12in rails price.

Thanks
Monty

[andromeda2015]

I have two questions in regards to your C4 rail. How does the rail contact the barrel nut? From the pictures, it looks like the barrel nut sits in a groove with very little contact. I am interested in your rail, but am concerned about the axial constraint of the hand guard. Or is the rail axial constraint dependent on the barrel nut contacting the groove shown in the pictures?

If by 'axial constraint' you mean rotation around the barrel axis, the rails have anti-rotation tabs at the rear that engage the upper receiver. Check out the pictures in this thread. As for engaging the barrel nut, I believe it is a pressure clamp around the circumference of the barrel nut, but others on this forum who have installed the rails would know better about this.

Its certainly a much tighter fit around the barrel nut than other rail systems I've used which clamp around it.

Coooool--I'm guessing a build with the 12" rail will be another couple weeks after you get them? I'm not in any huge hurry (hell, I've waited this long and I'd rather keep waiting to get an upper that meets your standards) but I will start optics-shopping a little more in-earnest now.:dance3:

[grinch]

It will be a couple weeks till the website gets updated with the C4 in the builds but you can E-mail me through the site for details of the build and we can work it out. I've actually got quite a few upper builds going out with the C4 rail.

Good to see you on Tactical Arms with LAV!

Question: When you were shooting the SCAR Long Range version I noticed you were keeping your thumb on the strongside not wrapped around... was this because you are lefty and that was a right hand set up rifle or is this a specific technique for longrange shooting that you use?

[grinch]

M4- That was a fun show to be on the crew and Larry are great guys I look forward to doing more with them.

I prefer not to wrap thumb around the grip when I'm shooting a precision weapon I just pull strait back on the grip into my shoulder it keep me from putting any side pressure on the weapon.

Thanks
Monty

[M4Fundi]

Thanks!

[jvencius]

Is there a torque spec for the 4 screws that clamp the rail to the barrel nut and the forward pair of screws that hold the halves of the rail together? I figure "snug"+ a dab of Loctite will be sufficient, but if there is a precise value I'd need to tighten the screws to, that'll go in the "good to know" file...

[ra2bach]

...These will all clamp to standard barrel nut but we plan to include an enhanced barrel nut in the 10 and 12in rails. We do not feel any rail clamping to a standard barrel nut has enough purchase when you get to a 10in and 12in rails. I know there are others that do it but we fell they are not sturdy enough to support the longer rails for hard use...
Thanks
Monty

er, nevermind...

[buckjay]

If you read the whole thread he goes on to say the enhanced nut is not needed so they stopped using it.


While we're on topic of nuts - did the rail come with a standard nut?

right, got it... :sad:

no, you use the existing standard barrel nut. hopefully you already have one holding your barrel on your upper... :p

[jonbondave]

Man, glad i found this thread, I think i'll be using one of these rails on my next build.

[68whiskeyncoke]

Does anyone know what size hardware the rail uses!? Mine didn't come with any!

Email Monty.
He'll make it right.

[68whiskeyncoke]

Unfortunately I am going overseas in a week and don't have time to have em shipped, was just going to head over to the local hardware store.

[shifter]

Monty has responded to every one of my emails in almost exactly 24 hours. I would have expected him to get tired of it by the number I sent him, but he always answered - and always under 24 hours. Just don't be surprised if it takes exactly 24 hours.

Ask him about the torque on the screws, too. I've not seen that answered yet - but I haven't been following this thread religiously.

[68whiskeyncoke]

Roger.

thanks

I know Monty will make things right, but if you are super short on time, go into the hardware store with the rail and fit the screws to make sure you've got the right ones.



ETA- The ones which lock around the barrel nut should be 8-32 socket head cap screw, the side one are 8-32 flat head, I'm not sure on the length.

The owner of Rainier Arms is a good friend of mine and the largest Centurion Arms dealer, email me your shipping info and I'll have him send a set of screws out to you ASAP. I talked with Monty and he is tied up right now on something, and Rainier Arms would be able to get them out to you quicker. It will still take a couple days (depending on where you live), but that is the best I can do for you.

If that doesn't work for you, send Monty and email and you will have the screws waiting for you when you get back.

I went and bought a 10" handguard today to replace my Troy MRF.

All I can say is HOLY CRAP the C4 is light, it makes my old Troy feel like a boat anchor.

It installs in about 30 seconds, if you already have your D-ring removed.

I like the fact that the screws thread into inserts rather than directly into the aluminum.

Here is a side-by-side pic, C4 on the left and the Troy MRF on the right:

It's easy to see why the Troy weighs 5 oz. more...

Here she is, naked:

11052

Here she is, all dressed up:

11053

I'm diggin' it so far, the only problem I had was with my sling mount - the Gear Sector screw ended up in the same slot as the button head screw that holds the front of the handguard halves together.

All I had to do was flip the mount around to move the screw into a neighboring slot so this was no big deal.

This is my new favorite rail system, hands down!

Is there something up with Centurian Arms? I cannot get their site to come up.

Same here.

I tried to get on their site tonight, as I wanted to get a price on a rail, and even though I typed in the correct site it came up with some advertising site.....

[zacbol]

Saw this as well. Someone forgot to renew his domain registration.

Whois indicates some variations were also registered. Tried this and it seems to work:

Sorry for the issue the sight is being worked on right now and we should have it back up in a day or so.

For you torque spec junkies out there

I have three 10" rails and torque the front two at 15 inch pounds and the rear four at 21 inch pounds using the Borka kit. I equate this off of various scope attachment screws and specs and all seems well. I witness marked everything and nothing moves. Oh-used blue thread locker on them also.

Practice on yours so that when you install mine you'll be a pro :D

I'm going to see how high I can go on yours:eek:

Will the 12" C4 FSP fit a midlength gas system? I've seen it on a carbine. The web site does not specify. Does that mean the fsp cutout will fit either?

I am not trying to be a jerk, but a little common sense would go a long way here.

[Iraqgunz]

This particular rail was made for midlengths- http://www.centurionarms.net/index.php?option=com_virtuemart&Itemid=179

I can't answer about the other. I am sure that Monty will answer if you email him.

[zgilbrech]

What are the torque specs if any for the bolts?

[ctrmass]

IIRC there arent any torque specs.
There are steel inserts, so they can take a good amount of torque, but common sense.
If youre concerned about them backing out, maybe some blue loctite is in order. I've NEVER had any such problem with mine, but YMMV etc.etc.

Sorry to ask a somewhat stupid question...but is the rail on this upper the same style being discussed in this thread?

Not a stupid question at all, Bravo Company uses Centurion Arms C4 rails on many of their builds, and the link you provided is certainly one of them.

Great! Thank you for the quick reply.

I'm looking at getting that upper sometime soon to replace my RRA Elite Comp upper.

[JBarbaresi]

since the thread was revived i'll throw up some recent pics, although i'm sure to piss someone off because they are also posted in the AR picture thread...

centurion c4 mid cutout rail on a centurion upper, thanks again monty.

did you assemble that upper or get it from centurion? might just be my eyes playing tricks but looks kind of like an m4 profile barrel and i didn't think monty offered those. either way, looks sick man
.

[IG11]

Got it straight off Centurions website. Not a M4 profile, probably just the shadows. Thanks

[Koshinn]

Stick, does the Centurion C4 Carbine or Mid cut-out rail work with an Adams Arms piston system?

I've always wondered that and no one seems to be able to give a straight answer.

Not really sure, while I own my fair share of weapons, the only piston I have is a POF.

Oh. I assumed you owned everything for sale on RainierArms for some reason, lol.

Are the interior dimensions of the upper part of the centurion rail equal to or bigger than a samson evolution's? Looking straight at the rail, I'd imagine it's from like 11 oclock to 1 oclock that matters.

[ctrmass]

A recent build. It's a 6.5 Grendel/264 LBC-AR:

No, though the owner is a good friend and I could probably borrow whatever I needed. What you see in my pictures is typically my personal equipment.

Good looking blaster.

[ctrmass]

Thanks.
IIRC that was the last pic that camera took.
Check out the shutter.:(

It's on a Sabre lower with a RRA 2st trigger, leupold mark AR on a Burris P.E.P.R. mount with a Black Hole barrel, and a Satern bolt..
The thing really shoots well!

[Stickman]

I was hoping that was something outside the camera... evidently not.

[kaptain86]

Hmm I still need to pick up a BCM upper with this rail...

[HeavyDuty]

I switched out an Omega for a Centurion Carbine Cutout to gain a little more hand space. Nice rail!

WHAA!?! based on your photos, you could supply a small army!

[buzz_knox]

This may have been covered and I just missed it. If so, I apologize. Assuming that one has a 14.5 pinned upper, can the 12" rail be installed over a shaved down front sight assembly? I am assuming so but wanted to be sure.
