The RF-15 features a standard flat-top upper receiver with a forward assist, brass deflector, and ejection-port cover, delivering a clean profile while retaining practical essentials. Receiver markings read "RADICAL FIREARMS, LLC • STAFFORD, TX USA," "MODEL: RF-15," and "CALIBER: MULTI."
Its 16 inch barrel is threaded and fitted with an A2 flash hider. A low-profile gas block sits under Radical Firearms' free-float RPR handguard, which runs roughly 15 inches and provides a continuous Picatinny top rail with M-LOK slots for accessory placement.
The rifle uses a direct-impingement, semi-automatic action and accepts STANAG-pattern magazines with a stated 30+1 capacity. Controls include a standard magazine release. The finish is matte black anodized throughout.
Furniture includes the Mission First Tactical Battlelink Minimalist adjustable carbine stock and an MFT pistol grip, keeping the carbine lightweight and ergonomic. The aluminum handguard and polymer stock components complement the rifle's full-size AR-15 configuration.
