FightLite Industries Mission Configurable Rifle Dual-Feed Complete Upper Features The FightLite Mission Configurable Rifle Dual-Feed upper uses short stroke gas piston operation to run cleaner and cooler than a direct impingement system a real advantage when cycling the higher round counts a belt fed gun invites. Its dual feed mechanism accepts both standard AR15/M16 magazines and linked M27 ammunition so the same upper can switch from a conventional magazine fed carbine to a sustained fire belt fed configuration. A precision machined 7075-T6 billet upper receiver and full auto bolt carrier give the assembly the strength to handle extended firing sessions. The 12.5 inch quick change barrel is threaded 1/2x28 and ready for the included RIP Brake compensator controlling muzzle rise during rapid strings. Built to interchange with standard AR/M4 uppers the MCR readily fits any mil spec lower receiver and remains rearward compatible with AR15/M16 rifles dating back to 1963 making it an easy addition to an existing build. The M-LOK handguard provides mounting space for lights optics and other accessories while the adjustable sight set offers a usable aiming solution right out of the box. A manganese phosphate finish over the black receiver resists wear and corrosion through hard use. Included hardware such as the belt feed main spring mil spec H3 buffer carbine stock spacer extended bolt catch mag adapter and 100 M27 links make this upper a complete package for sale at GrabAGun for shooters building a configurable belt capable AR-15.
