The FightLite Mission Configurable Rifle features a patented MCR upper receiver system that allows user configuration in seconds without tools to adapt to virtually any mission profile. Engineered for responsible armed citizens, law enforcement, and professional security personnel seeking to upgrade their rifle or carbine to MCR performance and capability, this system combines gas-piston operation for extreme reliability in adverse conditions with a 16.25″ quick-change barrel (3 seconds) and an M-LOK co-planar hand-guard with rail-interface system for optics and modern accessories mounting.
The MCR upper receiver assembly accepts standard box type AR15/M16 magazines or M27 linked ammunition at operator discretion, delivering unprecedented firepower and weapon flexibility across the capability range from optic-ready carbine through lightweight support rifle applications.
