Shoots great
Added this to a psa pistol lower. Ran 95gr 110 125 150185 & 220gr through it for function test. All shot well & locked back on last round except the 185 gemtech. Really low pressured but really soft & quite unsurpresed. Most rounds I got barely sub mom which impressed me being so short. A few grains went just barely over 1moa. I'll take that happily. Only complaint is the quick detach points on the hand guard. Becouse of the heavy barrel they are useless. My sling won't attach becouse the barrel is to thick to allow the swivel head to enter the rail deep enough to engage. Swapping it for a midwest that's on the way. They're rail has a bracket around the connect point that raises it up just enough. No big deal though. For the price I got the whole upper the accuracy & fact of how well it cycles almost every grain I'm satisfied with the purchase. BTW I ran it all unsurpresed.
