Fightlite Industries MCR060 Duel Feed 5.56x45mm NATO 16.25" Upper - 1913 Rail

The Fightlite Industries MCR060 is a complete AR-pattern upper receiver assembly chambered in 5.56x45mm NATO, engineered for direct fitment to any MIL-Spec AR-15/M16 lower. At its core is a 16.25" barrel with a 1:7" twist - the combat-proven rate that stabilizes everything from M193 ball to Mk262 and other heavy 70+ grain 5.56 projectiles.

The defining feature of the MCR060 is its Duel Feed upper, which routes ammunition from either side of the receiver. This ambidextrous feed path supports left-handed shooters, magazine conversions, and belt-feed setups, giving the platform true mission-configurable flexibility.

The upper is machined from 7075-T6 aluminum and wears a full-length MIL-STD 1913 rail handguard for unlimited Picatinny accessory mounting - optics, lights, lasers, foregrips, and bipods all lock directly to the rail. Adjustable iron sights are included for an out-of-the-box sighting solution.

Built to standard AR-15/M4 upper dimensions, the MCR060 is a drop-in fit for any compatible lower receiver, bringing Fightlite's combat-tested engineering to your 5.56 NATO build.
