The 18-inch barrel is stamped ARC 1:8, wears a light-gray finish, and is threaded to accept the included muzzle brake/compensator. The 1:8 twist rate is tailored to the 6mm ARC chambering to stabilize a broad range of bullet weights used in this cartridge.
A long, free-float M-LOK handguard with triangular/web lightening cuts pairs to a flat-top upper, creating a full-length 1913 Picatinny top rail across the receiver and handguard. The upper also includes a case deflector, forward assist, and ejection-port cover. An M-LOK QD sling socket is installed on the handguard.
The forged AR-15 lower incorporates an integral trigger guard with SAFE/FIRE selector markings and an RF logo on the magwell. An adjustable, collapsible carbine stock with rubber buttpad and QD socket provides an approximate 11–14 inch length of pull. The rifle is fitted with a B5 Systems-marked pistol grip.
This semi-automatic, direct-impingement platform uses aluminum receivers and is manufactured in the USA. It ships with no iron sights and is designed for detachable box magazines; no magazine is provided.
