Radical Firearms .300 Blackout AR Pistol 8.5" Barrel

Radical Firearms .300 Blackout AR Pistol

The Radical Firearms .300 Blackout AR pistol represents a thoughtful approach to compact rifle design. Built on proven MIL-STD upper and lower receivers, this platform delivers the versatility shooters demand in a maneuverable package.

Barrel and Gas System

The 8.5" chrome moly vanadium barrel features a heavy profile and 1:8 twist rate optimized for .300 Blackout ammunition. Melonite finish provides corrosion resistance and durability. A pistol-length gas system with low-profile gas block ensures reliable cycling while keeping the platform compact.

Handguard and Accessories

The 7" free-float M-Lok rail system isolates the barrel from the handguard, promoting accuracy while keeping your hands cool during extended shooting sessions. Generous rail real estate accommodates lights, lasers, and other tactical accessories without compromise.

Receiver Quality

Forged 7075 T6 aluminum upper and lower receivers with Type III hard-coat anodizing provide durability and reliability. MIL-STD components throughout—charging handle, safety, dust cover, and forward assist—ensure compatibility with standard AR parts and accessories.
