AR Stock Installation Problem *Pics added*

[Richard in LA]

I tried it that way with the same result....FAILURE!!

So, with that clamp completely removed, the threads bottom out before coming in contact with the buffer retainer?? Did you buy this stock new? If so, I'd be trying to get a refund.

 

[BayouBocephus]

yes but there is no point because the threads don't go far enough back to matter.

 

[BayouBocephus]

stock is brand new

 

[rockmup]

You need to return that stock. theres nowhere near enough threads. Odd, but it happens

 

[BayouBocephus]

Is there any way I can get it threaded with more threads??

I would return it to where you purchased it.
The tap used to cut those threads on the lower are 1-3/16"x16 TPI, If that helps. If you did successfully cut new threads, you would have non-anodized aluminum, which (I think) could possibly gall up. Maybe someone with more machining experience will chime in and let you know.

Call ACE, they should just swap it out for a new one.

I would really hate to have to go through the trouble of shipping the stuff back but I paid enough for I might as well.

Looking at the photos on Ace's web site, the threads on your stock look to be the same length as the ones there, I guess that's just how they make 'em.

If you just really don't want to send it back, just looking at the sloped shoulder on the extension tube it looks like you could take a round file and gently relieve the back of the hole in the receiver enough to let the tube screw in that last couple of threads. If you went slow and only removed the minimal metal necessary I don't think it would really harm the receiver, but still I'd really have to think about it before I did it if it was mine.

I would NOT cut my receiver to fit that stock. And that comes from the guy who cuts everything up !
Isn't that a pinch bolt right behind the threads ? Should be able to loosen that and pull it back right ?
I'd have to have it my hands to tell for sure but it doesn't look right.


EDIT; you are just a few threads short. Can you measure it ?

3 pages without the obvious answer ? CALL ACE AND ASK THEM WTF. They made the thing. Talk to their technician.

 

[cajun 22]

Maybe it's a commercial tube and larger than mil-spec thus not letting you screw it in any further. Just my two cents. Check with ACE and see what they say.

I've tried contacting them and had trouble getting to talk to someone
