The Radical Firearms FR16 5.56 NATO is built as a modern sporting rifle for range use and modular accessory mounting. Its design supports target practice and general-purpose shooting where a durable, configurable AR-style platform is desired. The rifle balances a compact 16-inch barrel with an extended free-float handguard for accessory placement.
The FR16 uses forged MIL-STD upper and lower receivers and a 15-inch RPR free-float M-LOK thin rail to provide a solid mounting platform while keeping hand placement cool. Ergonomics are addressed with a B5 Grip Type 23 pistol grip and a B5 Bravo adjustable six-position stock on a carbine buffer tube. The barrel is a Chrome Moly Vanadium SOCOM profile with a 1:7″ rate of twist and a threaded muzzle with an A2 flash hider.
