Overview

The Magpul B.A.D. (Battery Assist Device) Lever revolutionizes AR-15/M4 bolt manipulation by extending a paddle to the right side of the firearm, allowing shooters to release the bolt from the firing position using their trigger finger. This innovative design eliminates the need to break grip or shift hand position during reloads, significantly improving speed and efficiency in dynamic shooting scenarios.

Machined from durable billet 6061-T6 aluminum with MIL-A-8625F Type III Class 2 hard anodizing, the B.A.D. Lever attaches directly to the standard bolt catch without permanent modification to the firearm. The manganese phosphate Torx mounting screw includes a Nyloc Blue patch to prevent loosening under recoil, ensuring the device stays secure during hard use. The kit includes everything needed for installation, including a T8 Torx wrench.

While somewhat controversial in training circles, the B.A.D. Lever has proven highly effective for competition shooters and those prioritizing reload speed. The device allows for consistent, repeatable bolt manipulation without changing grip or looking at the controls. It's particularly valuable during timed stages or defensive scenarios where maintaining sight picture and grip consistency can make a critical difference.
