I love this upper.
Didn't write a review right away because I hadn't been able to get out and shoot it. I have now, and it shoots as well as I can aim. Shoots tight, extracts clean, fit and finish are lovely.

Outstanding value and quality by PSA.
Paired this to a PSA lower with a Shockwave Blade. After a short break in period it functions flawlessly with super and subsonic ammo. Very accurate with both ammo types. (Hint: loves Fiocchi SST ammo)
