FR16-5.56SOC-15RPR Threaded Barrel Rifle

The Radical Firearms RF FR16-5.56SOC-15RPR-CO 5.56 NATO rifle delivers precision and modularity through a purpose-built platform designed for shooters who demand accuracy without compromise. Built on MIL-STD upper and lower receivers, this 16-inch rifle pairs a Chrome Moly Vanadium threaded barrel with a 15-inch RPR free float rail system, isolating the barrel from external contact to maintain shot-to-shot consistency across extended firing sequences.

The free float rail architecture eliminates harmonics-induced deviation, a critical advantage for duty and training applications where repeatability matters. Cooling channels integrated into the 15-inch MLOK rail keep the shooter's support hand thermally comfortable during sustained fire, while the MLOK mounting standard provides unrestricted accessory compatibility. The carbine buffer tube, paired with a B5 Bravo stock offering six positions, enables proper stock-to-cheek weld and length-of-pull adjustment for users in body armor or varied kit configurations. The B5 Grip Type 23 pistol grip ensures ergonomic control, and the A2 flash hider reduces muzzle signature visible to targets and observers downrange.

This configuration suits law enforcement patrol carbines, defensive rifle training, and intermediate-distance marksmanship where shot placement consistency and accessory scalability are foundational. The 5.56mm NATO cartridge delivers proven terminal performance with extensive ammunition availability across commercial and duty-supply channels. At 8.2 pounds, the rifle balances controllability with durability across duty shifts or extended range sessions.

Radical Firearms positions this platform in the mid-range precision carbine segment, combining mil-spec standardization with thoughtful ergonomic and thermal management details. The 34.5-inch overall length, driven by the 16-inch barrel, maintains compact vehicle transport and room-entry geometry while preserving velocity envelope for 5.56mm ballistics.
