The RF-15 operates via a direct-impingement, semi-automatic system with a carbine-length gas setup and a 0.750-inch low-profile gas block. A manual safety selector provides familiar AR-15 controls, and the pistol ships with a 30+1 capacity using standard AR-15 magazines.
The 10.5-inch barrel is made from 4140 CMV steel and treated with Melonite for surface hardness and corrosion resistance. It is threaded 1/2x28 at the muzzle and fitted with an A2-style flash hider, offering a common thread pattern for compatible devices.
The flat-top 1913 Picatinny upper receiver includes a forward assist, brass deflector, and ejection-port dust cover. A free-float aluminum M-LOK handguard provides mounting slots at the 3, 6, and 9 o'clock positions and features a continuous top rail.
Forged 7075-T6 upper and lower receivers wear a Type III hardcoat anodized finish. The lower is marked "Caliber: MULTI" with maker and model markings "RADICAL FIREARMS, LLC, STAFFORD, TX USA" and "MODEL: RF-15," plus the RF logo on the right magwell. An SB Tactical pistol stabilizing brace with a hook-and-loop strap and a textured polymer pistol grip round out the configuration.
