Radical Firearms Forged RPR 10.5 Inch M4 Profile Barrel 5.56 NATO/.223 Remington Pistol

The Radical Firearms Forged RPR is an AR-pattern pistol chambered in 5.56 NATO and compatible with .223 Remington. It has a 10.5-inch 4140V chrome-moly vanadium barrel with a 1:7 twist and 1/2x28 threads carrying an A2 flash hider. A direct-impingement pistol-length gas system runs the action, and the forged aluminum receivers carry a flat-top upper with a full-length Picatinny rail. One 30-round magazine is included.

The 10.5-inch barrel and 27.25-inch overall length make this a compact AR pistol for range sessions and for shooters who plan to customize it. The free-float M-LOK handguard lets you mount lights or grips where you want them, and the flat-top upper is ready for an optic. Confirm the rules where you live before ordering a pistol-length AR build, since those rules vary.
