The Radical Firearms RF-15 RPR .300 Blackout stabilizer pistol pairs a 10.5-inch heavy barrel with an MFT Minimalist pistol stabilizer in place of a shoulder stock (brand part no. FP105300HBAR10RPRBMPSB). Radical Firearms builds it on forged MIL-STD receivers with a 10-inch RPR free-float rail and a pistol-length gas system, which cycles reliably with supersonic and subsonic ammunition. The rail leaves room for a light, a grip or a laser. It is a good choice for a suppressor-ready .300 Blackout pistol with a stabilizer already fitted.
