Decent for the price
Seems to be a decent upper. Was very happy with the value of the purchase. Like a lot of PSA items the quality is perfect but for the money it is good. I was able to get an 3/4in grouping at 50m. Which is fair considering. Haven't tried different rounds or loads yet. My only concern was heat building up at the gas block. After dumping a mag it was already starting to glow. But for the price it seems fabulous.

10.5 m-lok upper
Recieved in 5 days after ordering granted I live in SC. But pretty pleased with this pistol upper so far. Square stamped t-marked upper like my ruger AR 556 and few other ARs I have. Mlok rail was lined up correctly with upper receiver and flash hider was properly timed. Only thing I can say that i guess i really didn't like was the gas block had the set screws and not pinned but doesn't matter to me anyway for the price. Matched it up with Aero Presicion lowerPSA full auto bcf and c-handle and had very tiny slop but the Aero Lower has the adjusting screw in the grip to fix that. Put 40 rounds the day i got it 223 and 556 pmc and has no ftfs. It was getting dark so really didn't pay to close attention trying to really site it in but held avg groupings. All in all I'm happy with the purchase. Looks great and functions great. So for the price can't beat it.
