OPTION DETAILS
GAS BLOCK: Standard or Adjustable. Adjustable is a great option if you are using a suppressor or just want to fine tune your system.
MUZZLE DEVICE: Standard A2 Flash Hider or Competition Muzzle Brake. Muzzle Brakes are for recoil reduction. The baffles and ports are milled larger to drive pressure up and to keep the muzzle down more effectively.
Bolt Carrier Group: BCG is Optional. Select Nitride or Nickel Boron if you need a BCG to complete Upper . All our BCGs are M16 Profile, Properly Staked Gas Key, MP Tested, 8620 Carrier, 9310 Bolt. Nitride is a surface hardening process that creates a tough and slick surface. Nickel Boron provides the slickest surface which reduces friction and where dirt does not easily adhere to.
Enjoy the heavy-hitting ballistics of the .30-caliber cartridge without the need for NFA tax stamps or braces. The PRO2A 16" 300 Blackout Pistol Length Non-Reciprocating (NR) Side Charging Upper Assembly delivers modernized platform operation by replacing the traditional rear charging handle with a heavy-duty, left-side charging lever. The handle stays fully stationary during live-fire cycling, providing a seamless operational zone free from moving external components near your optic mount. Built around a standard 16-inch barrel configuration for full rifle compliance, this upper utilizes a pistol-length gas system to guarantee smooth operation with sub-sonic and supersonic ammunition alike. Drops natively onto any standard Mil-Spec AR-15 lower receiver. Proudly 100% designed, machined, and precision-assembled in the USA.

Shooters who want the heavy brush-hunting capabilities of the 300 Blackout cartridge but want to avoid the legal hassles, paperwork, and registration associated with short-barreled rifles (SBRs) or pistols choose this standard 16-inch setup.
Hog and predator hunters utilizing bulky low-power variable optics (LPVOs), thermal systems, or complex night vision frames prefer side-charging platforms. The left-side handle clears the wide undersides of scope mounts, protecting hands from scrape damage.
Shooters planning to run a muzzle suppressor on a full-sized stock layout choose this solid side-charging platform. The enclosed billet design eliminates the open space found under standard rear charging tabs, keeping backpressure blowback completely away from the shooter's breathing zone.
