Excellent upper for Competition or SPR build
For the money I do not think you could find a better 18" SPR upper. Built mine for tactical / 3 Gun competition and this works flawlessly, great accuracy and low recoil with a wide selection of amm0 from 45 grain .223 to 77 Grain 5.56 OTM.
Lightweight and easy to maneuver:paired with an extended charging handle and NBC BCG. Could not be more pleased with this purchase.

If it functioned it would be fine
Received this product in April. When I finally got out to the range, rifle wouldn't cycle.
After replacing the gas block with an adjustable gas block (and making sure the gas port was aligned), I brought it to the range a second time - ran through the gas block adjustment starting at full close.... at 3/4 open it finally threw brass, at full open it still wouldn't lock the bolt back.
I'm thinking the gas port in the barrel is out of spec. One way or another, this upper isn't performing as it should.
