PRO2A 16" 45 ACP 1/16 Pistol Caliber NR Side Charging Melonite Upper with Flash Can

Description

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.

Key Features

  • Non-Reciprocating Charging Control: Features an advanced side-charging layout with a handle that remains entirely static while cycling, preventing optic mount interference and maximizing charging leverage.
  • Forward Concussion Redirection: Outfitted with a slimline aluminum linear Flash Can muzzle device that channels noise, flash, and concussive pressure away from the operator and side bystanders.
  • Full Carbine Length Ballistics: A full 16-inch barrel squeezes maximum velocity and energy out of the heavy-hitting .45 ACP cartridge while staying fully non-NFA compliant out of the box.
  • Straight Blowback Simplicity: Operates completely without gas blocks or gas tubes, dropping complex wear points to guarantee steady feeding and extraction cycles with heavy loads.

Why Choose This Product?

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.
