The FightLite MCR Dual-Feed Complete Upper (brand part no. MCR-060S) is a 5.56 NATO / .223 Remington upper built around a 12.5-inch barrel and a full-length picatinny top rail, part of FightLite Industries’ Mission Configurable Rifle system. FightLite engineers the MCR platform around configurability, giving the upper a dual-feed design that supports feeding options beyond a standard AR-15 magazine well setup. This is a complete upper assembly, ready to mount to a compatible lower, built for shooters who want a purpose-configured 5.56 upper from a manufacturer known for unconventional, mission-driven firearm designs. It suits precision-minded builders who want a shorter-barrel 5.56 upper without sacrificing top-rail real estate for optics and accessories.
