LMT DMR Stock

[bp7178]

It uses a carbine RE instead of a rifle one like the PRS.

I was wondering if anyone used it, how solid it was on the tube, and how quickly it could be swapped for a standard M4 type stock.

Looks interesting...I too would like to hear more about it.

[Ark1443]

Very interesting. If I ever do a precision build, I'd consider this.

[mrvip27]

definitely something I might consider. kinda wish it was a rifle length tube.

wonder if it fits with an a5 7 re? probably have to use the 5/6 position a5 tube

[mtdawg169]

Huh, I saw these a while back and just assumed that it was a Magpul PRS. Guess not.

I will be getting one soon for the recon build. I talked to LMT on the phone and the guy didn't know how short the LOP will go in inches but with its adjustability on both the reciever extension and the buttpad I am hoping it will go shorter than 13" LOP. The Magpul PRS is nice but just too long for me. The DMR7.62 version is designed for the MWS which has the same overall length receiver extension as the Vltor A5 tubes, that version should "fill the gap" a regular 6 position carbine stock would leave. He was not able to tell me if the DMR556 was long enough for A5 but since they make 2 versions I am guessing not. The DMR762 is the ticket with A5 tubes EDIT: the DMR762 stock will not lock in the forward most position on either the A5 7 position tube or the A5SR 6 position tube. Of coarse if you don't mind the gap, the 556 stock would have better compatibility across rifles, since, unlike rifle length tubes, the stock can be swapped out quickly onto another lower just like a regular carbine stock.
Overall I think the people who write this stock off as a PRS copy havn't looked close enough at the details, can't wait to try it out!

That's great news. I've gotten impatient lately trying to make a decision, because each time I think I want to get an A1 stock on the MWS, I talk myself out of the cost and labor.

The $50 stock is one thing, but then changing the buffer length, shipping to someone who will change the stock, it all adds up close to what the cost of this is anyway. At least this way I won't be without one of my favorite rifles for an undetermined amount of time.

Any word on how long until the 762 comes out? If it's one of those "soon, but not sure how soon" things from LMT I'll assume that means another year or so and jump on the 556 version. Gap? That's why Allah gave us hockey tape...

[bp7178]

I'd like to know how the adjustment and/or installation & removal is done. It would be pretty bad ass if it was tool-less.

[Steel head]

I'm really interested in one of these for my SPR with a A5 extension.

[jerrysimons]

After tinkering with the DMR762 stock I have found that it does not fully collapse on either a standard 7 position A5 receiver extension or the 6 position A5SR/AR10 receiver extension. While the internal dimensions and overall length of both A5 tubes are the same as the LMT MWS receiver extension, the rail part of the MWS RE, with notches for stock adjustment, are shifted forward maybe 1/4". Or conversely, the A5 tubes adjustment notches are shifted rearward 1/4". I am still trying to figure this out but I think the DMR stock bottoms out on the back of the A5 RE while still in between adjustment notches. BUT ALSO, the really confusing part, is the front of the stock does not fully reach the end plate and castle nut when in its forward most position. Not sure how this can be if the A5 and MWS tubes are same overall length but the DMR762 will not fully collapse on either A5 tube and is not locked in a notch when it is in its forward most position.

The stock works beautifully on an MWS though! And to be fair it still works on A5 tubes, just don't expect full collapsibility.

I also tried on he MWS RE a Colt CAR stock that normally rides on the A5SR/AR10 6 position RE where it sits flush with the end of the tube when collapsed to notch 1. The MWS tube poked out the back of the stock about 1/4". More like is the case when you put a carbine length, open-backed stock on a standard 7 position A5 tube. This illustrates for me the difference in the adjustment notch placements of the MWS RE and the A5 RE tubes.

I think if one desired full collapsibility of the DMR762 stock with use of A5 buffers and rifle spring on an AR15, the way to do it is to order the LMT DMR762 stock with a spare MWS receiver extension.

I am still trying to figure how the DMR556 stock differs dimensionally from the DMR762.

So the 762 will at least fit on a 7 position A5, correct? I can live with it not collapsing fully; I'm mainly interested in it for the adjustable cheek piece.

[Sevcrist]

I'm interested in this stock but it's hard to find much information about it. The link below is the best I have found for pictures and a brief write up.

Yes. Here are some photos that show the difference between the notch placement on the reciever extensions. Right to left: VLTOR A5 7 position, LMT MWS 6 position, A5 SR/AR 10 6 position, V7WS Carbine 6 position. The MWS RE has its own notch placement whereas the A5 mirror the placent of the carbine RE notches.

Notice how the stock only locks into a slot in its most collapsed position using the MWS RE. The A5 tubes seem to bottom out on the back of the stock while the pin is in-between notches. The stock butts-up against the castle nut and end plate on the shorter carbine RE in-between notches. Surely the DMR556 would not hav this issue on the carbine RE since it is shorter.

If someone likes I can post pictures of the stock in every notch it will lock into on each RE.

Awesome pics, thanks for the reply. Told me exactly what I needed to know.

This stock was definitely made to be a perfect precision option for the MWS platform. However, also good to know it will fit relatively well on the VLTOR RE. For the Larue 7.62 PredatOBR shooters in the crowd, we are all holding out hope that SOMEDAY Larue will sell individual barrels of different lengths, profiles, and calibers. They are really adamant about the "whole rifle" concept, but they would clean house even more if they offered barrels. Imagine a PredatOBR that transforms from an 18" heavy OBR profile barrel to a light 14.5 barrel in 2 mins. This stock paired with either the LMT MWS RE or the VLTOR RE would be a perfect compromise...longer than carbine length but not as cumbersome as rifle length. The magpul PRS is great for precision shooting when you want that full rifle length buffer system. But if you swap for a lighter barrel and need a compact/collapsible stock, this option from LMT is great. Collapse the DMR, or just swap it out for something else. Just gotta bite the bullet on price... :)
