Ok, coming up.Yeah I am just waiting to see pics of the messed up polymer lower.
Is your buffer tube screwed in too far? Possibly?Well guy's I did receive a lower from PSA and built it with steel parts. Looks great! But!! it doesn't fit the upper at all. Just doesn't match and no amount of filing will get it to fit correctly. So looks like I will have to just sell it for parts. I did repair the lower with JB-Weld and waited 3 days to file and drill. So it works good actually. Range on Thursday should find out if it was worth it, and if it works. NEVER BUY A $399 POLYMER AR EVER!
No it's fine the upper doesn't match up to the PSA lower because it has a different curve to it.Is your buffer tube screwed in too far? Possibly?
I don't know if this really helps now that I have it back together.Ok, coming up.
I have a PSA upper on an Anderson lower, fits like a snug glove.I've heard that PSA lowers need a PSA upper, not sure why, but that information is consistent from several sources. Buy a PSA upper receiver for your lower I guess is an answer.
