View Full Version : Keymod direct mount for bipod?
Does anyone know if Noveske or Vltor (or anyone else for that matter) has made a direct mount for a Harris bipod for Keymod rails?
I don't like the idea of an adaptor stacked on another adaptor.

Here was my solution . . . The Noveske sling swivel stud for the Troy rails worked. I can't imagine anything else being lighter or lower profile. In stock at Noveske (http://noveskerifleworks.com/cgi-bin/imcart/display.cgi?item_id=trx-ss&cat=165&page=1&search=&since=&status=&title=).
Not sure if I have seen anyone post this up yet, but I had a Noveske lopro sling swivel stud for a Troy handguard sitting around that I thought I would see if it fit my new NSR upper. . . it did.
The threaded backplate has a raised section that sits in the Troy Alpha/TRX holes. For the NSR, I just flipped it over so the flat side is resting against the flat side of the inside of the NSR. The washer that rests in the outside of the Troy rails fits nicely in the larger part of the keymod slots.
It just happened to time perfectly. I am not thinking I will keep this here, but it is convenient for zeroing and may be worthwhile for someone else.
Here are a couple simple pictures.
You can just see the raised portion through the hole in the NSR. That is the raised part that would sit in the Troy holes.

My argument against Keymod in a nutshell.
The sling swivel stud will get you rollin... but you're effectively back to 80s/90s era mounting.
True enough, but I think the market will come along and provide direct mount options so you don't need to add a 1913 rail before adding something else.
It's just a matter of time.
I use the Noveske Swing Swivel as shown above. Seems to work well and is probably the best bet at this time.
Mark, You can always throw in a short piece of rail if you want to use a rail mount bipod. I bet you would like the system better if it came with an assortment of rails and what not.

Fair enough but the idea of an adapter upon an adapter is exactly what keymod is doing away with over non-direct mount modular rails with only 1913 rail section attachments. The only common accessories not yet available in keymod direct attach are a vertical grip and a bipod.

Really wish atlas would make a direct keymod mount. If some more details come out about the harris mount from IWC I may have to go that route I guess. I cant seem to find any more info on the IWC mount.

I used this on my Noveske 13.5" NSR and it worked great. Now I havent put hundreds/thousands of round through it, but I functioned very well when zeroing my irons and Aimpoint PRO.

I don't like the idea of "Stacking" mounts to attach anything. Direct Attaching anything, light, sling, bipod, is what we're all about. Minimalist, clean, as few parts as possible, just what is necessary.
Primary Weapons Systems (http://primaryweapons.com/store/pc/viewPrd.asp?idproduct=532&idcategory=54) and Odin Works (http://www.odinworks.com/K_Pod_p/acc-k-pod.htm) are the two commercially available designs that use way over engineered "Adaptors" which cost in the $30 - $40 range. And they both contain a Sling Swivel Stud for attaching Harris-style BiPods.
Our design is a sling stud for Harris-style BiPods. Our design allows the BiPod to rest directly against the KeyMod rail, unlike the PWS & Odin versions, which the BiPod rests against the adaptors:

Impact Weapons Component's (IWC) KeyMod BiPod Mount incorporates a sling swivel stud CNC machined from stainless steel. IWC's proprietary stud design drops through a single KeyMod slot's round hole and is retained by a removable Spiroloc (like our QD MICRO SlingMount). There are two grooves for the Spiroloc in the stud to accommodate various thicknesses of KeyMod rails as well as a tension device (not shown) to remove vertical play (shown in the pic, between the KeyMod Rail & Spiroloc), eliminating rattle when the BiPod is removed. Remove the BiPod and you're left with a Sling Swivel Stud and that's it. Remove the Spiroloc and the stud comes out. Since IWC's Stud is retained by a Spiroloc, there's ZERO chance it will accidentaly become detached and cannot loosen up over time like multi-piece or threaded design. There's no Loctite required or to come loose. The part shown is an un-plated pre-production piece. Production units will be black.
NOVESKE (http://noveskerifleworks.com/cgi-bin/imcart/display.cgi?item_id=trx-ss&cat=165&page=1&search=&since=&status=) makes a multiple-piece Sling Swivel Stud that threads together for around $16 with Shipping.
We have not settled on final pricing, but it will be competitive like all IWC products.

Impact's Mount-N-Slot looks interesting, but I'm still trying to get a handle on how it works.
They pitch it here on a KeyMod thread, their photos on the website have it attached into a Moe carbine forearm, and the copy only references picatinny rails.
Anybody have any better photos or seen this thing in person.
I'll be using this on the flat-bottomed Seekins SP3R handguard, so maybe a larger mount might work for me, but still, something this low-profile looks appealing.

I bought the noveske trx studs and they work awesome on my nsr and mcsr rails. I dont see any need for anything else u less you dont want the bipod to touch the rail then the pws mount would be the way to go. If yoh can wait I spoke with atlas and they will be coming out with a direct keymod attach system as well. Ill use the trx studs for now then switch to the atlas once it becomes available.

I tried a PWS mount first on my Seekins SP3R, but eventually moved to Noveske TRX mount.
The PWS took up three slots, while the Noveske is just a single stud so only took up one. This has allowed me to move my bipod further down the handguard and closer to the muzzle. I'm very pleased.
That said, the PWS folks were great to deal with when trying to track one of their mounts down - everybody seemed to be either out of stock (online) or unwilling to order one for me (locally). I ended up special ordering directly through PWS.
The only thing I don't like about the Noveske Sling Stud is that the backing plate hits the gas block when mounted to a 13.5" NSR with an intermediate gas system... I had to move the bipod back a few slots to keep the free floatedness.
I may need to try the IWC mount. Hopefully it clears.
The folks at Impact Weapons Components were kind enough to send me one of their new Keymod Bipod Mount-N-Slot mounts. It is very minimalist but well thought out. You will have to remove the handguard to mount it and installation is extremely easy. Once the handguard (NSR in my case) is removed simply place the mount into the Keymod opening from the inside. Backtrack for just a sec: Before inserting the mount there is a rubber o-ring in a groove right above the base to install. Afterwards the final stage is turning the handguard over and a snap ring must be installed. Right above the groove where the o-ring sits there is a flange with two smaller grooves. Place the snap ring into whatever smaller groove is closet to the handguard. That's it. Reinstall handguard. Very very little up and down play and the mount easily rotates.
For $7.95 it is $2 cheaper (from Noveske's website) than the NSR/TRX bipod mount. I like the simplicity of it and there nothing that needs to be threaded. Also I don't have a picture of it but that particular rifle with the NSR has a .750 profile barrel forward of the handguard shoulder with a Vltor set screw gas block and the IWC bipod mount does clear the gas block when mounted directly underneath. Nice little product and excellent job IWC!

In the pic you can see the 2 small grooves on the flange that you place the snap ring in. Depending on which one is closet to the mounting surface of course:

Awesome, thanks for clarifying a few things I was curious about. I may just have to get one of these now since it's been confirmed that it clears the gas block.
Your welcome. It barely clears but it will.

That swivel stud irritates me on two levels.... Now I know it's cheap and it's a temporary work around until direct attach pods are available... BUT...
1. You have to take the damned rail off, and
2. You're back to mounting a Pod like a 1980's hunting gun.
Defeats the Keymod system completely.

I will argue one thing with you, taking the rail off isn't a complete con. I got to clean some of the crud out of there! ;)
;)
Yeah... I'm kinda fannatical about removing stuff... especially when my Zero'd BUIS is attached to one of the parts to be removed.
Isn't there another thread about this very topic? I vaguely remember posting pictures about something or another.

Totally agree. Having to remove a keymod rail to attach anything is moving backwards & completely retarded IMO.
I did purchase the Noveske TRX stud for my NSR but I was able to snake it in from the end of the HG with a forceps. I only have one bipod, that moves between other guns, so the swivel stud is my only option at this point.

I read those instructions three times to make sure I saw it right. I thought Keymod was all about ease of taking accessories on and off?

It is (as well as minimalist in design), but some keymod accessories aren't quite there yet in development.
I'm perfectly happy with the TRX stud on my NSR. I didn't have to remove the NSR, and it wasn't any sort of chore getting the stud mounted. Unless Harris changes the way they design their bipods to mount, there is not other way to mount one.

This isn't the fault of the Keymod design... This is the nature of the swivel stud.
Ideally we'll attach pods directly to the keymod slots eventually.

IMHO...
At IWC, we think making a Bipod mount out of Billet, with screws and KeyMod nuts, and selling it for $30+ just to add a sling swivel stud for a Harris Bipod to a KeyMod rail is a waste.
OdinWorks, PWS and soon others will make the type of Bipod mounts which you're referring to. We could have too, but IWC's all about making a fighting rifle functional, lightweight and reliable. Our component places a Sling Swivel Stud for a Harris Bipod as close to the bore as possible. Or just what's needed to do the job, reliably, at low cost and unobtrusively. It's so small, there's no need to remove it once the bipod is removed. Just like an 80's hunting rifle.
Yep. It is what it is... and it's priced great. If it works for people, by all means.
The root problem here is that people are using caveman Pod attachment still. ;)

I agree with point #1, however point #2 and beyond is neither Keymod nor IWC's "fault". The product is specifically designed to allow people to attach an easily obtainable and cost effective Harris bipod to a Keymod handguard. It's not intended to be a Keymod based bipod. Big difference in how you look it.
I see your point... but as a man without a smart phone and a truck with hand crank windows.... I still feel that a stud mounted pod is some prehistoric livin.
Last time I did that was 5 years back... and that's just because it was a rimfire rifle.

Agree on the prehistoric mount. Hopefully people will make direct attach bipods soon.

I had my kid's friend ride in my truck once... and she saw the hand cranks and was like...."These are COOL!!".
Like Jaxman, IWC sent me one of their bipod mounts to check out, as well. Jaxman pretty much covered everything in his review, but I do have a couple profile pictures to show how far it protrudes on the inside of the handguard:
Noveske stud with a government profile barrel and shaved FSB:
http://i.imgur.com/Ac93nMG.jpg
IWC stud with a Noveske SPR barrel and low-profile gas block:
http://i.imgur.com/qVjpbzH.jpg
The IWC does protrude slightly less, but unfortunately for my specific setup it wouldn't allow me to place it right below the gas block. This is probably due to my barrel being the SPR version, which has a .875" gas block. I suppose if I left the flat o-ring off it would sit down in the keymod slot further, but then it would also be loose, since there isn't a third c-clip ring to take up the slack. Not a big deal, really, and probably won't affect the majority of users.
Ultimately I definitely prefer the IWC over the Noveske, even if I did have to remove the handguard to install it. I like that it can swivel freely and doesn't rely on tension and/or loctite to remain secure when my bipod isn't on the rifle.
I ordered the IWC adapter. Works great. Arrived fast with a hand written note thanking me. thought that was pretty cool on a small item. Good deal.

I'm trying to decide between IWC KeyMod Mount-n-Slot or Quick Connect to a small picatinny rail? I haven't purchased either yet, or the bipod. Been reading favorable posts about Harris/LaRue. I don't necessarily need the quickest connect/disconnect but I am lazy and do want the easiest but yet sturdiest mount. Also don't know how long I want to wait to see if a bipod w built-in keymod mount is made?
The mount I mentioned above takes 3 seconds and no tools to take off. Mounting a rail is a little quicker but adds an adapter on an adapter and the mount hangs off the rail instead of being flush. Plus it costs a lot more.

Noticed your Harris is not mounted furthest forward toward barrel end. Is there a benefit, or pros/con, to mounting bipod in furthest hole forward? I'm trying to avoid installing/removing/re-installing Mount-n_Slot.
it's mounted in the second from last slot. It just feels better to me there that all. Just personal preference. You may find the last slot is better for you.
Thanks for the feedback and advice.
I wish someone would come up with a direct mount keymod setup for my atlas bipod.

More stability. I'd put the pod in front of the muzzle if I could get away with it. We had a buddy with a heavy barreled bolt gun that only allowed the pod to get so far forward. It was like a teeter totter, trying to shoot that thing. Horrible.

I have to remove my handguard, the IWC cant be maneuvered inside the handguard w/o taking it off. Don't know if I am going to attempt to remove and reinstall handguard or take it to gunsmith. Obviously I'm a novice at this.
There is a reason Noveske / bcm / vltor do not make one. KM does not like stressed mounting. Load the bipod. Watch it loosen. Tighten it. Watch it loosen. Loctite and tighten. Watch it loosen. Remove it and observe the bent edges of the mounting hole.

WS6,
Does the bent edges occur with just the IWC KM Mount-N-Slot or all bipod mounts including rail section adapter?

It will occur with anything mounted to a Keymod rail that takes a beating. Bipods properly used, are typically taking somewhat of a beating when you load them up, etc. Maybe a weekend-shooter from the bench will be fine, but actually USING it, it's just not advisable. The very thin edges are the cause of this, and the stronger the material, the better off you are. For example, I would feel better about using the KAC rail than I would the KMR.

10-4. I fall into the casual catagory, thanks for the explanation.

WS6, this is a bit extreme. :) If loading a bipod attached to a two keymod nut picatinny rail is enough to bend the aluminum of the rail in the keymod slots, then that's a really crappy rail. Or something is wrong with the picatinny rail section. I have personally tested some of our mounts past destruction, which means taking a scout light or my g2x in the appropriate ring mount, installing it on a rail, and beating the light on the ground until something breaks. I have never had one of our mounts rip out of a keymod rail, or even loosen up. The rail either starts to collapse (want to see an ovalized KMR?), or the mount bends/breaks. The keymod slots are fine. The reason for this is that the mount is supporting the keymod slots on the outside.
Edit (additional info): The only time I have seen a mount rip through keymod slots is when the user installs it wrong, like when they don't have the recoil lug in the right place, so the mount isn't flush with the rail. This typically means the rail gets damaged when they tighten the part down because the keymod nuts get pulled too far into the slots, spreading them open, and leaves it very weak to being ripped through.
Now, back to bipods:
The Noveske bipod mount is a combo part, and works on the Troy TRX rails, too. As such, it contacts the flat areas on the inside of the keymod handguard, and won't deform a keymod slot when excessive force is applied. It doesn't engage the chamfer in the keymod slot at all. I've had one installed on an NSR with a Harris bipod for almost two years, and used it in classes, competition, and regularly shoot out to 500 yards at my local range. It has never loosened up, and hasn't damaged the rail, despite the Harris being on there all the time.
The IWC bipod stud doesn't thread into anything, and also doesn't engage the chamfer in a keymod slot either. It's held in with a c-clip. I have one of those as well, and while it doesn't have quite as much contact surface as the Noveske, it hasn't ever damaged one of my rails. The Harris has so much surface area contact with the underside that it's really not something I would worry about.
IWC KeyMod Bipod Nount-N-Slot installed; wasn't too bad. I did have to remove handguard. It was a little tricky getting the supplied retaining ring on. 1st one wasn't on correctly (I'm guessing) and the adapter fell out while I was re-installing handguard. As stated by a fellow member, good thing they give you two. The second retainer ring is on but I'm not too sure of stability? Just to be safe, I spent a couple of pennies and purchased 3/8" External Retaining Rings from home improvement store to have on hand.
Im a huge fan of a BCM aluminum rail section always being mounted at 6 o'clock on all my keymod rails with the Larue Harris bi-pod bouncing back and forth between them. Quick on and off with a solid lock up.

I have a video of me beating a Keymod BCM VFG against a table as hard as I can.
It did not move.
The DD keymod bipod adapter looks pretty good and can be installed with the rail attached.
We will see how it holds up.

I am sorry to say the IWC KeyMod Bipod Nount-N-Slot did not work out for me.
If you have medium big fingers... assembly will be a pita. Plan on having some dental picks handy. I did finally get it assembled... and I am quite "mechanical minded"..... only to come home from the range to find it had lost the retaining clip. I suspect the retaining clip was not a full enough, it looked to be about 270 degrees of a circle. That does not match the images on the IWC webpage. So it is just hanging there.
I know it was assembled correctly.. since it took 3 tries with my Shrek fingers to finally get it right.
I had bought another one for later use, but will not bother to ever use it.
Off to the workbench to remove the BCM KM rail......
Bfoo,
As stated above, I purchased 3/8" External Retaining Rings from home improvement store. They are a little beefier, easier to handle, and better fit than the supplied retainer ring if you wanted to give hit a last try. They come with ends facing in towards ring and facing away from ring, I purchased the outer.
Pws has a bipod adapter that is fat finger friendly. There are others that are similar I'm sure.
