At Pickett's Mill Armory, we take pride in selling upper receivers that are crafted from the finest materials. Each of these short-barrel rifle receivers is test-fired before shipping to ensure quality and safety.

Our 9mm upper receiver features an M4 flat-top receiver. The 9-inch tactical free-float keymod rail is designed to allow you to mount items and attachments while staying off the barrel so as not to affect harmonics thus enhancing accuracy. It has a black anodized finish that meets military specifications. Please note that this 7.5 inch upper receiver does not include a bolt carrier and charging handle but they can be added. Order this upper receiver today for precision, quality and safety you can count on.
