The Radical Firearms BTR AR pistol in 7.62x39mm (brand part no. RF01876) runs the same mil-spec receiver architecture as the rest of Radical’s RPR lineup, chambered to feed the AK-pattern round through a mag-fed AR platform. Radical Firearms builds it around a 10.5-inch heavy-barrel profile, threaded and black finished, and wraps it in a 10-inch RPR free-float handguard with M-LOK slots that keep hands clear of the barrel. The black polymer grip pairs with MIL-STD upper and lower receivers for a duty-grade fit, and the pistol ships with a bare receiver extension in place of a stock. Among AR pistols chambered for AK-pattern rounds, this BTR configuration favors shooters who want 7.62x39mm’s power in a compact AR-style package.
