The Radical Firearms RF-15 RPR AR pistol in .300 AAC Blackout (brand part no. FP105300HBAR10RPRBMPSB) pairs a 10.5-inch heavy barrel with a pistol stabilizing brace in place of a shoulder stock. Radical Firearms builds the pistol on MIL-STD upper and lower receivers and wraps the barrel in a 10-inch RPR free-float handguard, keeping hands clear of the barrel while opening up room for lights and grips. A selector-switch safety runs the controls, and the receiver carries a full Picatinny top rail for optics. Among AR pistols chambered for .300 Blackout, this braced RF-15 configuration favors shooters who want a ready-to-shoulder close-range platform.
