Fantastic upper
I paired this upper with an MOE EPT lower initially. It's a very soft shooting upper. It's also a very accurate upper. With good match grade ammo I can put up sub moa groups. With my hunting ammo of Barnes 62grn TSX ammo I can do MOA with it. It loves the Barnes ammo. After about 300rnds I put this upper on a Seekins Precision lower, and O M G. The fit is fantastic with ZERO play between the billet SP15 lower and the forged PSA upper. I mean zero play between them. They matched up great, and look great. What's more, they function awesome together. If you enjoy 18" ss uppers, this is an awesome upper. Oh yea, with the rifle length gas it throws cases to about 3:30-4:30, depending on what ammo your using.

Great upper
Linked with a 6x24x50 this thing is a tack driver out of the box. A quality product at a good price. Good quality barrel !

This upper is part of my first ever AR build. Since completing my build, I've put 400 rounds through it, and I've had zero failures so far.

The stainless steel barrel is really nice, and it's accurate too! I've gotten 1.42" groups at 100 yards, with Magpul MBUS 2 iron sights.

I could surely close the group, once I upgrade to a good 1-8x scope.

Fit and finish was good. The nitride on the free float rail was thin in some places, however, it was of no concern to me, as it's going to be a woods/hunting/self-defense rifle, it's going to see wear.

Overall, I'm extremely satisfied with my upper and would and have recommended it to my friends and family.
