Maximize your downrange kinetic impact, velocity scaling, and pistol caliber carbine precision on specialized AR platforms. The PRO2A 16" 10mm Pistol Caliber Upper Assembly is meticulously engineered to harness the raw power of the hard-hitting 10mm Auto cartridge inside a stable rifle-length footprint. Built around a premium forged 7075-T6 aluminum receiver optimized for pistol caliber casings, this system centers on a 16-inch medium profile barrel. The full length completely burns intermediate handgun powders, unlocking a significant velocity premium over standard pistol frames to maximize flat trajectories. A reliable direct blowback operating system ensures heavy-duty structural cycling without the need for delicate gas hardware, while an extended 12-inch free-float aluminum handguard wraps the barrel to supply extensive accessory placement space and superior modular handling.
