Fixed Stock for AR That’s Not an A2

[DMW1116]

Just wondering what my options are for a 16” rifle. I’d like to replace the adjustable stock with a fixed one. I have an A2 but I know there are others out there that are lighter and maybe won’t require me to get a new buffer tube.

Just wondering what my options are for a 16” rifle. I’d like to replace the adjustable stock with a fixed one. I have an A2 but I know there are others out there that are lighter and maybe won’t require me to get a new buffer tube.

My go-to buttstock for the AR is the A1. It's 5/8" shorter but uses the same buffer tube, without the 5/8" A2 spacer. I'm of the opinion that the A1 is a better fit for most people, and it's a must if you're wearing heavy clothing.

A1 stocks are getting hard to find. If you run across one, buy it. Even ones in poor condition can be restored.

I’d like to replace the adjustable stock with a fixed one ... won’t require me to get a new buffer tube.

I run Strike Industries fixed modular Viper stock (Adjustable for length of pull and needs Mil-Spec diameter buffer tube) for my 16"/18" PCC/AR with carbine length buffer tube for bench testing (Produces smaller groups than adjustable stock) - https://www.midwayusa.com/product/1021317628

I also use aluminum rear monopod (Stores inside the stock) - https://www.strikeindustries.com/si-strike-mfs-pod.html

I use the ACE skeleton stock.

It's light and minimalist. Without the butt pad I think it's the same length as an A1 stock (my preference)

I'll see if I can find a pic

ETA pic. It's a pic from 2016 but the rifle is configured almost exactly the same way

Another ETA

I think it's this

Another vote for the A1. It's the perfect size for me - I had already setting my adjustable carbine stock to the same length.

If you have an A2, it will fit right on your existing tube. You just need to remove the spacer and use a shorter buttstock screw.

Brownells sells replica A1 stocks for $40.

I haven't seen one of these in a while but Magpul still makes their MOE fixed stock:

I have resorted to gluing a plastic spacer inside the stock to tighten it up. I have to pull hard to move it. I cut plastic from "clamp shell" package and wrapped it around the tube leaving the rail uncovered, then cleaned plastic and stock applied glue and installed stock until glue set up. I applied wax to the rail and removed the adjuster hardware from the stock

It sometimes amazes me how 5/8" makes a difference to people. I have used the M16A1 and M16A2 while wearing LBE and a flack jacket. And I wore both the Vietnam era or Desert Storm era flack jackets. that 5/8" difference between the A1 and A2 never bothered me nor did I even notice the difference. I notice more of a difference in my Zero when zeroing the rifle with or without a flack jacket on. But we were not trained to shoot "nose to charging handle" either.

To keep on topic, yes there are plenty of options for a fixed stock that still uses the rifle length buffer tube.

 

[DMW1116]

I wasn’t clear for my reasons or current setup. I have an M16 A4gery type and a 16” M4 type with adjustable stock. I use the M4 as a DMR even though it’s a 16” instead of an 18” barrel.

After doing a little dry firing with the A2 lower on the 16” upper, I’d like a fixed stock on the 16”. The A2 stock is good but if I can avoid swapping out the carbine buffer it would be nice. Something lighter wouldn’t hurt my feelings either.

Something lighter wouldn’t hurt my feelings either.

Strike Industries Modular Viper stock is 12.8 oz with all the extensions used.

The A2 stock is good but if I can avoid swapping out the carbine buffer it would be nice. Something lighter wouldn’t hurt my feelings either.

I have made a spacer to fill the extra space in an A2 stock to utilize a carbine buffer/spring.

Looks like I’m not the first to come up with the idea though.

Keep it

and embrace it when you are layered up with winter clothing or armor

I like the BRAVO COMPANY adjustable, it’s very solid, stable, and durable

PS- if you decide to replace the buffer with a fixed stock type, be careful of the two spring & detents that will want to fly off

once controls the buffer tube, the other the rear take-down pin

Fixed stock for a carbine tube. Looks good.

I knew of the Magpuls, but not the Strike Industries.

MilSpec receiver extension

Commercial receiver extension

Much cheaper than converting to a rifle receiver extension with stock.

I notice the difference with a magnified optic mounted, not so much with iron sights or a red dot. Body position and eye relief reasons.

I’m using this Luth-AR Skullaton rifle length stock with a Limbsaver medium slip in recoil pad for this 450 BM rifle.

Very light and affordable.



Otherwise this is a good idea mentioned earlier for a carbine which I used on my 224 Valkyrie:

I have also used this one on a 450 BM. It is not the lightest but I still recommend it highly.

I think it's shorter than an A2 also.

Somebody help me out here....why switch the stock? Why not leave the current stock in place, at whatever custom length you want, and then NOT MOVE IT. Just because it's adjustable doesn't mean you have to adjust it. What don't I understand? Aesthetics? Weight?

Greater precision.

During comparison range testing of PCC loads at 50/100 yards, I found with Just Right and AR based PCCs, use of adjustable stock produced larger groups than fixed stock, even though same ammunition was used. (@Walkalong and others that shoot precision/long range matches point out even small uneven pressure of cheek weld and shoulder pocket placement could deviate POI away from POA)

So I use fixed stocks for precision load testing. When CA required pinning of adjustable stocks, I found if there is play or wobble after pinning, POI deviation from POA still happened. So I relegate the use of adjustable stocks for RAWs (Registered Assault Weapon).

Now, if your shooting application is range blasting fun/plinking at closer range, then use of adjustable stock may not matter.

 

[Varminterror]

Magpul UBR. Done. It’s the only tool-less telescoping stock which is solid enough for precision work, but retains that adjustability to suit multiple shooters in multiple positions.

There are 3 fixed stocks I’m willing to use today - Luth-AR, Magpul PRS, and XLR. Any other application where I’m not using one of these, then I’m using a UBR.

I run the Luth-Ar adjustable on my 16" DMR-

One nice thing about the Luth-Ar stock is it has a tensioning screw you can crank down to "fix" it in place once you get it setup the way you want. Zero wobble on mine....this thing is scary accurate for such a short, non-floating rifle.
Yes it does require an Allen wrench, but there is a small clamp on the stock to hold the wrench.

Magpul UBR ... Luth-AR, Magpul PRS, and XLR

I like Magpul products and used their stocks, mags (AR and Glock), BUIS, AR furniture and 1911 thumb channel grips.

I was actually looking at Magpul PRS stock but since I just needed to eliminate adjustable stock's play, decided decent fixed stock (But I wanted adjustable length of pull) would be workable for my bench testing application and settled on Strike Industries modular Viper stock due to adjustable length of pull and the aluminum monopod for rear that stored inside the stock just pushed me over the fence (And pricing is very attractive at $43 compared to $190 for UBR and $247 for PRS).

Nice.

For CA, adjustable stock is no longer allowed and must be pinned. But Luth-Ar would be viable option for pinned featureless and RAW ARs.

I may have to try one of these, the monopod is very reasonably priced too.

 

[Mauser lover]

I’ve got a Magpul MOE too. I like it well enough. It’s cheap enough. It’s light enough. And it doesn’t pull the hair out of my chin.

 

[Varminterror]

I should have specified, the Luth-AR I use is the fixed/rifle tube version. I used the carbine version on my son’s AR when he was littler so I could slide completely in to ~10.5” and still have adjustable cheek rise, but it’s still a carbine stock - if you lock it too far forward, it blocks the charger with the cheek elevator. But I really like their fixed/rifle tube stock. Much easier to balance than the Magpul PRS since it’s lightweight.

The kids snagged me a Strike Industries fixed stock. Now, how do I put this thing on?
