This AR-15 upper assembly features the Radical Firearms generation 3 15” FHR Hybrid Rail System that has a new mounting system that ensures the handguard stays tight against the barrel nut and receiver. It is a free-float design, meaning it does not contact the barrel which could result in inconsistent accuracy like standard M4 delta ring handguards. It has Keymod slots along the sides and bottom with built-in picatinny rails at the muzzle end for mounting any tactical accessories that you want.

This significantly reduces both felt recoil and muzzle rise, aiding the shooter in staying on target even during full auto fire. The rear-angled side ports with generous top ports are exceptionally effective, allowing for faster follow-ups and dramatically reducing the effort required to stay on target.
