PRO2A 16" 10mm 1/16 Pistol Caliber Melonite M-LOK AR-15 Upper

Product Description

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.

Key Features

  • Optimized 16-Inch Muzzle Energies: Full rifle length stretches out 10mm ballistics, offering absolute velocity extraction and massive kinetic impacts for defensive applications or medium varmint control.
  • Heavy Duty Blowback Operation: Bypasses gas tubes and gas blocks completely, employing a simplified, high-durability direct blowback bolt arrangement that reduces structural cleaning variables.
  • Resilient Free-Float M-LOK Architecture: Premium 12-inch slim profile aluminum rail isolates the barrel from external handling pressure vectors, ensuring continuous point-of-impact accuracy.
  • Liquid Bath Nitride Hardening: The 4150 Chrome Moly Vanadium steel core features full interior and exterior QPQ Melonite coating to offer absolute weatherproofing and prolonged bore precision.
  • 100% Sourced & Assembled in the USA: Built to tight manufacturing metrics in Georgia, backed completely by premium custom-shop engineering quality parameters.
