The Pro2A Tactical 16-inch .45 ACP Non-Reciprocating (NR) Side Charging Complete Upper Receiver assembly featuring an integrated linear Flash Can delivers exceptional blast mitigation, maximized velocity, and premium ergonomics to the AR-45 platform. Hand-assembled and quality verified in Georgia, this system replaces the traditional rear charging handle with an advanced, static side-charger mechanism. Paired with a linear flash can that pushes muzzle blast and concussion safely downrange away from the operator, this drop-in setup offers an ultra-clean, tucked aesthetic built for competition, home defense layouts, or heavy large-bore tactical training.

Building a hard-hitting .45 ACP rifle configuration often introduces massive frontal surface challenges and unrefined muzzle lines due to traditional open brakes or hiders. The Pro2A 16" .45 ACP NR Side Charging Upper with Flash Can solves these layout limitations entirely by choosing a dedicated linear device that pushes concussive forces away. Mated to a robust billet receiver featuring a factory-headspaced blowback bolt group and an enhanced feed cone optimized for defensive hollow points, it operates flawlessly without hitch. It is the premium drop-in evolution standard AR operators look for when outfitting a serious, non-NFA carbine build.
