The B.A.D. Lever is designed to considerably improve the speed and efficiency of the AR15/M16 bolt catch. It quickly addresses reloading and malfunction clearance shortcomings by extending a paddle to the right side of the weapon, allowing manipulation of the bolt stop from the fire control/ready position with the right-hand trigger finger. Functional for both left and right-handed shooters, the B.A.D. Lever also allows traditional bolt catch manipulation according to the AR15/M16 manual of arms. All mounting hardware included.*Note- Not compatible with 7.62x51 (.308 Winchester) firearms as well as most AR15 billet or polymer lower and upper receivers due to their larger non-standard dimensions (including the S&W Magpul Spec Series lowers). Made in the USA.
