Ok. So I just finished my lower on a build for the most part but the stock is having a weird issue.

Basically, even after tightening down the screw at the end of the stock there is a gap between the stock and the rear of the receiver.


I can't figure out what it would be. Is this a usual problem caused by something I did/didn't do or could it be a bad part.
The stock is a PSA A2 kit.

Lower tab of stock not fitting into the lower receiver? Shown near the takedown spring...

It fits in fine. It just will wiggle back and forth (in and out of the tab on the buffer). Think of wearing shoes slightly too large.

Must be missing the spacer that goes onto the end of the buffer tube? Your screw is bottoming out and needs the A2 spacer, otherwise the buffer tube is not long enough to fit the stock right...

That's what I was thinking.

The little extra cap that goes on the end of the buffer tube / receiver extension, right?. Its already there and in the stock.

I followed PSA's instructions on using a wire brush to remove some of the thread lock on the screw, and I can't get it any tighter without it starting to strip (I think it is bottoming out anyways), so I am kinda at a loss. The picture I didn't post is what happens to the butt pad when you slide the stock forward to meet the receiver; a gap forms at the top of the butt pad where it meets the stock.

PSA says the parts are MIL-SPEC, but if they are screwed up they are screwed up. I honestly would not be looking forward to having to do a return with them because they are damn near impossible to reach by phone and by the time they actually got the return and shipped out a new one I get the feeling it would be another 2 to 3 weeks, at which point I will have moved back up north to my apartment in Wisconsin for school so I'd have to try and get my address with them changed.


*Edit* Is there an easy way to remove all the red threadlock? I have heard heating it will remove it much more completely than a wire brush. Do you think that would help / what do I have to lose from trying?

I've seen that happen once before. Issue was the the screw was not put in correctly - was forced in parallel to the end of the buttstock, rather that being in line with the extension (buffer tube). Therefore, the screw did not go in all the way. Took the screw out, and forced it back in correctly (same axis as the extension) and problem solved.

The screw was partially in when I opened the package, could that have cause an issue? The box looked like it had gotten knocked around a bit and the tube was just wrapped in kraft paper.
How much force" are you talking about and should I try to align the screw without the stock first?


*EDIT*: I did some more searching and it seems I am not the only person who has had this issue on the internet. Most people have said it is the disturbing amount of locking compound on the screw and removing that makes it go together just fine. I will try that when i get home, although I'm not sure the best way to remove it. Heat supposedly works, but I'll have to either find the soldering iron or use the oven.

The problem has been resolved. The cured LocTite that was put on the screw was preventing it from fully seating.
A bath in some dichloromethane / methylene chloride, followed by a wire brush and finally a pin to clear out the threads solved the problem.

Good to hear.

That was my problem too. Remove the LocTite and it works great.

Where is your steel spacer that goes between the LR and the stock.? I think that is your problem.

the spacer sits btw the buffer tube and the stock.  it's on the back end, not the receiver end.

The spacer that comes with the Palmetto A2 stock is plastic.  Any issues with going with a plastic spacer vs. a steel one?

None whatsoever.  If you had to use the buttstock in a hand-to-hand combat situation, the buttplate, which is plastic would give in before the spacer gets crushed.

No not in that application.. I think they were actually made of aluminum...
It wouldn't surprise me if the plastic ones were also considered milspec...
