Reliable, accurate and good-looking
All the things I wish I was, this upper is.

No idea how PSA is putting out this level of quality at this price, but please don't stop.

Very pleased.
This upper was easy to zero, and put together well. The finish is already wearing on the brass deflector, but I didn't put this together to be pretty, I wanted it to work and work right; and it does.

0 for 2, let's try for 3.
I ordered one of these to replace my Brownells upper (currently sitting on a PSA lower) and I really wanted a mid-length with M-LOK vs my existing carbine length with keymod. The first one came in, and the barrel was about 1/4" off (if looking from the top, to the left) of the hand guard. Removing and examining the hand guard, there's no way to adjust it's center, and it is lined up where the hand guard meets the upper, so it's likely an issue with the barrel nut.

I returned it for a replacement/exchange, and got one with the exact same issue.

I'm actually not positive I didn't get the same one back. I'd used Red'n'Tacky to get the sights on, and there was grease on the new one where the sights had been. There was also a blemish in the same spot on the hand guard. Picture and video attached to show the issue.

To make sure this doesn't happen, I asked if they could examine the next replacement before it goes out, which I was told wasn't something that they can do.

To make sure I don't get the same one again I ordered another one, and will return the original when the new one comes in.

Cosmetically, this wouldn't bother me, but I do plan on shooting with iron sights, and having the front that far off made it impossible to get the sights to line up properly.

Great upper at a great price, not one issue in 1000 rounds, wish I could have used this in Afghanistan instead of Uncle Sam's loner. Thanks for everything you guys do PSA, great job will purchase again!
