Radical Firearms FR-16 Features The Radical Firearms FR-16 is built on a forged mil-spec upper and lower receiver set with an M4 feed ramp forward assist and dust cover for reliable function under hard use. Its 16 inch barrel is threaded 1/2x28 and fitted with a mil-spec A2 flash hider while the 1:7 twist rate stabilizes a wide range of 5.56 and .223 Remington bullet weights. A 0.750 inch low profile gas block keeps the handguard slim and the barrel profile clean. The M81 woodland camo Cerakote finish covers the metal surfaces giving the rifle a distinctive field-ready appearance that stands apart from a standard black build. Up front the 15 inch free float M-LOK handguard includes a top Picatinny rail for mounting optics lights or lasers while leaving the sides and bottom open for M-LOK accessories. The B5 Systems Bravo stock and matching grip provide a durable ergonomic platform that holds up to repeated use in the field. At an overall length of 36 inches and a weight of 6.8 pounds the rifle stays maneuverable without feeling light or flimsy. Shipping with one 30-round magazine the FR-16 is ready to run straight out of the box for hunters home defenders and range shooters alike.
