finally I got a break to hit the range today, shot a couple of boxes of blemished 223 reloads, everything worked fine except for the aftermarket mags( 11 round bulgarian polymer Ar mags) I used, once I switched to USGI used mags, the complete unit functioned real good as I expected it would
so for those concerned the 80% blem lower pictured above, that is now 100% functioned flawlessly
Awesomer! I should have one put together soon to test.
