NOTE: This upper receiver has a barrel that is less than 16” in length and is intended for use in AR pistol or legal short-barreled rifle builds. Other configurations may violate Federal law.

The Stern Defense Complete 9mm Receiver Group comes fully assembled with all the features you want in an AR-9 carbine. All you need is a standard AR-15 lower receiver and compatible Stern Defense pistol magazine conversion kit and your PCC is complete. This Upper features a 8.5” barrel precision machined from 4150 chrome moly steel with a chamber designed to be reliable with anything from common plinking rounds to defensive hollow points. It features a 1:10 twist rate, which is more than enough to stabilize all weights of 9mm ammunition. Attached to the 1/2x36 threads is the Stern Defense Forward Blast Diffuser that directs all gas forward instead of to the side, making it great for indoor ranges or when shooting next to someone. It is machined from 6061 aluminum and designed to follow the contours of the handguard for a streamlined look. Since it is a blowback 9mm design, no gas system is needed. This upper receiver combined with a magazine conversion kit will turn any Mil-Spec lower into a reliable pistol caliber carbine great for competition or plinking.

The free float M-LOK handguard is lightweight, durable, and offers plenty of room for customization. It is machined from 6061-T6 aluminum with a hardcoat anodized black finish and is attached with a steel barrel nut and rigid locking system. It is extremely slim with a 1.435” inner diameter, making it extremely comfortable to hold. The picatinny top rail continues onto the 7075-T6 aluminum upper receiver. This receiver is built to Mil-Spec with the forward assist and dust cover installed. It houses the heavy 9mm blowback bolt. This bolt features a Glock cut and is machined from 4140 billet AISI steel with a Manganese Phosphate coating. It has an internal weight that adds up to 15.5 total ounces but can be removed for an overall weight of 13.3 ounces. In order to work the bolt, this 9mm AR-15 upper receiver group comes with an enlarged latch charging handle. The large, textured latch makes it easy to quickly charge your rifle with an open palm.
