FightLite MCR Dual Feed AR-15 Complete Upper Receiver - 5.56 - 16.25" - Picatinny

The FightLite MCR Complete Upper Receiver gives AR-15 owners a true multi-mission platform, letting one rifle move seamlessly between magazine-fed carbine duty and belt-fed sustained fire. Built for shooters who refuse to be boxed into one configuration, this drop-on upper delivers gas-piston reliability with a barrel you can swap in seconds.

Features:

• Tool-free quick-change barrel system swaps in about 3 seconds
• Dual-feed design accepts AR-15/M16 magazines or M27 linked ammunition
• Gas-piston operation for reliable cycling in adverse conditions
• Full-auto-rated bolt carrier group, optic ready
• Co-planar rail handguard for mounting sights and accessories
• Includes RipBrake muzzle compensator and mag adapter

The 16.25-inch MCR upper drops onto any mil-spec AR-15, M16, or M4 lower without permanent modification and is even backward-compatible with lowers dating to 1963. Its quick-change barrel system lets shooters reconfigure barrel length in seconds, while the MIL-STD 1913 Picatinny handguard puts rail space on all four sides without sacrificing the co-planar sight line the MCR is known for. Every MCR ships with a main action spring, bolt catch, carbine stock spacer, mag adapter, RipBrake muzzle compensator, M27 links, and an operator's manual.

FightLite Industries pioneered drop-on belt-fed AR technology, and the MCR remains its flagship system for shooters who want maximum configurability from a single lower receiver. It's engineered and built to stand up to high round counts.
