The Rebel has the primary controls laid out just like an AR-15. In fact, the Rebel uses a standard AR-15 trigger/fire control group and safety so upgrades with aftermarket AR accessories is a breeze. The aluminum upper and monolithic M-LOK rail with a full length Picatinny rail provide a rock-solid foundation for whatever optic you want to mount on the pistol. For ease of carry a Quick Detach end cap accepts QD sling mounts or can be removed to mount a receiver extension tube and arm brace.
