FightLite Industries MCR 5.56 NATO Complete Upper, 16.25in Barrel

The FightLite Industries Mission Configurable Rifle (MCR) complete upper (brand part no. MCR-556-DFR) pairs a 16.25in 5.56x45mm NATO barrel with a full-length 7075-T6 aluminum handguard built on the MIL-STD-1913 Picatinny standard. FightLite designed the MCR platform to be modular and duty-ready, and this drop-fire-ready configuration ships as a complete, ready-to-mount upper rather than a parts pile. The one-piece rail runs the full length of the handguard for uninterrupted mounting real estate, letting a shooter run optics, lights, and grips wherever the build calls for them. It’s built for shooters who want a rifle-length platform without assembling a barrel, gas system, and rail separately.
