I have an A2 buttstock and was looking at replacing it with the CAV Arms A1 because I'd like a little bit less LOP.


Do I just use the same buffer tube that came with the A2 and just subtract the spacer?

yup

ETA:  You'll need the shorter screw also.  Or you can cut down the A2 screw.

Thanks!


Ah, I didn't think about the screw. No problem.


I always wondered if the spacer was there to go from A1 to A2 length....




Thanks again.

and depending where you got it,  you may have to canabalize the screw that holds the sling mount from the old stock.  Othere than that, it's a straight forward swap.

IIRC my CavArms A1 Stock kit came with the short screw, but not the sling swivel or screw for it.  I also kept the butt plate from my old A2 stock, as it seemed quite a bit more durable.

Now with pictures.

But to be fair I posted it in the DIY forum.

FalArAk added it to his big, tacked building hints thread there too.

I like and use M16 stocks.
These are Pre-A1 updates.
Rubber buttpad.
No trap door.
Lighter weight.
Same length as an A1.

In fixed stocks, it's almost all I run anymore...



Northridge International usually has them for a song...

It's NOT a recoil pad.
It's a buttpad.
No softer than the hard plastic or metal plates, but it is more rounded, which causes it NOT to snag when coming quickly to the shoulder.
It's also lighter than the models with a trapdoor.
Those are my reasons why I like the original M16 stocks.
When I shoot, I have a shooting bag in the bed-toolbox of my truck.
I don't need to carry a cleaning kit, bolt or batteries.

The early one's I've seen ARE rubber ...... umm "buttplates" . I'm w/ you though on lite my rifle is an A1 20", it's no 9-10 lb monster .

Does ANYONE in the AR world make a damn A2 stock with a RUBBER buttplate?

As it stands, Les Baer Custom makes the most attractive A2 stock without the trap door (which I like) but I would really like a replacement buttplate in RUBBER.

The Cav Arms butplates/trapdors are crap.  You will want to reuse your A2 buttplate/trapdoor.

Brownells sells Colt A1 stock screws.

A1 length is some good stuff. I went from a Bushmaster fixed M4 stock to an A1 trapdoor and I couldn't be happier with the improvement in my cheek and nose weld. The only downside is the trapdoor A1 butt plate blows infected, pus-filled donkey balls. It's glossy smooth, doesn't want to stay put on my shoulder, and it cracks like a sumabitch at the top stock screw hole.

I purchased a DPMS A2 buttplate and dremeled some material to relieve stress where the contours don't match up perfectly. It doesn't look all too purdy but 300% better function than before makes it worth it.

The A2 screw can be cut down to fit as necessary. Minus the spacer. Go to midwayusa.com and look for the A2 butt plate to replace the OEM Cavarms one. The contours should match better than on an original A1 stock. If you've got some epoxy/JB weld or electrical tape, you can tighten the fit of the buffer tube and stock by slowly building up the thickness of the tube.

Is the CAV Arms A1 buttplate really that bad?

I don't want anything that will crack easily. However, this rifle isn't going to be subjected to any kind of heavy use. I won't be buttstroking anyone, or doing any marching/drills either.


What do you all think if I get the Fulton Armory A1 shell, then use my A2 buttplate? I'm assuming the Fulton A1 shell is compatible with the A2 buttplate minus some minor fitting like described in earlier posts...?

Cracking would mean that it was brittle.  The butt plates they use are the exact opposite, being made from a very hard rubber.

I haven't checked their site in a while, but I'm pretty sure that Fulton is selling original style A1 stocks, not the CavArms stocks.  If that is the case then cracking can be an issue for the stock itself, not the buttplate.

Everyone is correct that the shorter UPPER screw is needed for the A1 stock; however, a LONGER screw is needed for the lower butt screw since the A1 sling swivel is located further forward than the A2.

don't use an A1 slwing swivel screw on the C1...it's too long and if you crank it down you can damage the stock.
