So they may not work with an upper receiver that’s been modified for 9mm specific operation.īut, this upper receiver is well-built and well-priced. Some 9mm bolt carriers are designed to work with standard AR-15 upper receivers. Unfortunately, these modifications mean that this upper receiver is only compatible with most 9mm AR-15 bolts. So this saves you some weight bulk that you don’t need. And most 9mm bolt carrier groups don’t even have notches for a forward assist anyway. You don’t really need it on a 9mm carbine. Then, the forward assist has been left off. But this makes this upper receiver compatible with a broader spectrum of 9mm bolt carrier groups, since not all 9mm bolt carriers have a notch for the ejection port cover. It might seem like a bad idea to remove the ejection port cover. This improves the reliability of your 9mm AR-15, since it helps reduce ejection issues. And the ejection port cover has been removed to accommodate the way 9mm casings eject off the bolt face. The ejection port is slightly shorter and wider. They made the necessary changes and left off all the equipment you don’t need on a pistol caliber carbine. This upper is essentially a mil-spec AR-15 upper receiver that’s been modified for running 9mm. And the Rainier Arms Forged Mil-Spec Upper offers the same blend of quality and affordability as all their other parts.
