I just finished putting together my first lower, and I have a question about the A2 stock. No matter how tight I make the screw, there is a little bit of play in the stock, I can twist it back and forth slightly. Is this normal? If I install it without the spacer, it doesn't do this, what is the point of the spacer?

Will upload a picture later.

Thanks in advance!

Just bumping this to try and get a reply.

I've searched this site and others and cannot get an answer.

Do I need to use the spacer?

You need the spacer.
Usually you can still get a couple of turns on the screw with a big screwdriver. Make sure you use the correct size to avoid stripping the screw head. I've had your same problem and the stock tightened up after I gave it the extra couple of turns. Use a screwdriver tip on a ratchet for extra leverage if you must, but be sure to keep the screw tip seated well in the screw.

Thanks, I actually chipped it a little bit cause I don't have anything close to big enough.  Will probably order a new screw when I order the rest of my parts.  I actually really don't like the stock, but being in a ban state, I can't have a collapsible.  Might just order an ace stock instead.

Yes you need to use the spacer for an A2 as it connects the end of the buffer tube to the butt plate.

The buffer tube was originally designed for the shorter A1 stock bodies, when they made the A2 stock longera spacer was added but the buffer tube remained the same.

The fact that is wiggles does mean something isn't quite right. Since it doesn't wiggle without the spacer I'd try filing or grinding a little off the spacer then you could torque it down further. You may also have to remove the same amount off the top butt plate screw as it extends into the buffer tube and the buffer may bounce against it.  Guys run into this problem when converting from an A2 to an A1 stocks and soon find out that the A2 screw is too long by 5/8"

If you bought the stock from a dealer you could always send it back for replacement.

You can have a collapsible M4 style stock if it's pinned in place so it can't move. All you need to do is drill into the bottom buffer tube rib and stock body 1/2 or 3/4 the way through and pound a roll pin in place to lock it, many did this during the Federal AWB. Since it's "blind pined" its not easily removable or able to be converted easily. You could search the Equipment Exchange for a post-ban collapsing stock too.

I ordered it as a kit from PKFirearms. Will try to tighten it a bit more, just don't want to overtighten it.

I have a pinned collapsible stock on my Bushy M4, and I hate the fact I can't do anything with it.

Update,

I used a crescent wrench with a screwdriver and was able to get enough torque to tighten it up so it doesn't wiggle anymore.

Thanks for the advice.  Now I need to order upper parts.  As soon as the credit card billing cycle ends, will order some more.

I just used the biggest screw driver I had to tighten the hell out of it.  I actually had to tighten and loosen it a couple of times to wear down the hole in the buttplate a little bit.  Each time I did this I was able to get the screw in a little bit further.  Eventually it went far enough to where there was no wiggle left.

You can use a small washer on the screw also.
