The Radical Firearms RF-15 is a .300 AAC Blackout AR-15 (Radical Firearms part no. RF01708) built around forged MIL-STD upper and lower receivers for a rifle that fits and feels like the AR-15 shooters already know. Its 16-inch barrel is wrapped in a 15-inch thin free-float rail system that improves accuracy, keeps hands cool during extended strings of fire, and leaves plenty of room for accessories. A B5 Systems grip and stock provide a comfortable, secure hold whether shooting prone or upright, rounding out a build that’s equally at home at the range or in a home-defense role. Feeding from a 30-round magazine, the RF-15 gives .300 Blackout shooters a straightforward, well-built platform for both supersonic practice and suppressed subsonic shooting.
