The B.A.D. (Battery Assist Device) Lever is designed to significantly enhance the speed and efficiency of the AR15/M4 bolt catch. By extending a paddle to the right side of the firearm, it allows the bolt stop to be manipulated with the right-hand trigger finger from the ready position, streamlining reloading and malfunction clearance. Built for use with Mil-spec forged upper and lower receivers, the anodized aluminum lever attaches to the standard bolt catch without requiring permanent modifications. Suitable for both right and left-handed shooters, it also maintains traditional bolt catch functionality in line with the AR15/M4 manual of arms.
