FightLite Industries is a U.S. manufacturer of specialized weapon systems and AR-compatible accessories. Its MCR (Mission Configurable Rifle) is a belt-fed upper receiver that mounts on a standard AR-15 lower, converting it to a light machine gun configuration with quick-change barrels and the ability to switch between belt-fed and magazine-fed operation. The SCR (Sport Configurable Rifle) pairs a traditional fixed-stock lower with AR-15 upper receivers, making it compliant with regulations that restrict pistol-grip configurations while retaining full upper-receiver compatibility. FightLite also produces lightweight handguards, enhanced charging handles, and mounting systems.
