This complete upper assembly from PW arms comes with everything needed to transform your standard AR-15 rifle into a 5.7x28mm powerhouse! The top mounted magazine (not included) holds 50 rounds, and eliminates a protruding magazine that may interfere with prone shooting. The clever design ejects spent casings down the empty magazine well, eliminating flying brass and hot cases going down shirt collars.

The upper receiver and rails are precisely milled from a monolithic block of 7075 T6 aircraft aluminum, and will accommodate any style of sighting system. Features an ER Shaw 16" barrel with flash hider, and no gas system to get fouled which makes maintenance a snap! Uses commonly available FNH PS90 magazines, and fits on any standard AR-15 lower receiver.
