Speed Up The Bolt Catch with this B.A.D. Lever from Magpul

The B.A.D. Lever (Battery Assist Device) is designed to considerably improve the speed and efficiency of the AR15/M16 bolt catch. It quickly addresses reloading and malfunction clearance shortcomings of AR15/M16 platforms by extending a paddle to the right side of the weapon.

It allows the manipulation of the bolt stop from the fire control/ready position with the right-hand trigger finger.
