Bought a gfla upper on gb and the prices was quite right (just couldn’t trust radical arms as they review really bad). I put it on my lower and fit pretty good. I got the blues barrel w the np3 coated bolt head.

50 yards off a deck railing and sand bag I was getting 1/2 in groups w hornady FTx fact ammo. Complete function w gfla mags, great function, great extraction, great ejection!!!

Kicked about 2x the 223 ar I’m super impressed!
