B.A.D. AR15/M16/M4 Ambidextrous Bolt Catch Kit
The Battle Arms Development Ambidextrous Bolt Catch Kit provides a complete right- and left-side bolt control solution for AR15/M16/M4 platforms. This billet-machined upgrade enhances both the engagement surface and ergonomics of the bolt catch, while adding true ambidextrous functionality through the integrated BAD-EBC-AMBI Battery Assist Device. The result is faster reloads, quicker malfunction clearing, and more efficient manual-of-arms operation without shifting your firing grip.
Full Ambidextrous Bolt Control
The kit combines the Enhanced Bolt Catch (BAD-EBC) with the ambidextrous BAD-EBC-AMBI lever, extending bolt lock and bolt release capability to the right side of the rifle. Shooters can lock the bolt open or release it using their trigger-finger side of the receiver, streamlining handling during rapid reloads, administrative actions, or high-intensity shooting.
Enhanced Paddle Geometry
The BAD-EBC features improved paddle contours with increased surface area for positive engagement. Whether charging the rifle, performing a bolt lock-back, or executing a malfunction clearance, the enhanced geometry offers better leverage and tactile feedback than a standard Mil-Spec catch.
