The Radical Firearms RF-15 BTR 7.62x39mm pistol puts the AK cartridge into an AR-pattern platform with a 10.5-inch heavy barrel (brand part no. RF01876). Radical Firearms builds it on forged 7075-T6 upper and lower receivers with a 10-inch RPR free-float rail, and the BTR brace takes the place of a shoulder stock. A carbine-length gas system and a low-profile .750 gas block keep the front end clean. It is a practical pistol for shooters who already stock 7.62x39mm ammunition and want it in a compact, accessory-friendly format.
