Battle Arms Development AR-15 Ambidextrous Bolt Catch Kit

This kit gives an AR-15 lower full ambidextrous bolt release and bolt catch control. You get the BAD-EBC Enhanced Bolt Catch, the BAD-EBC-AMBI lever, a T10 Torx screw and a T10 Torx L-wrench, so it suits a new build or a gun without the enhanced catch.

The steel parts have a black phosphate finish, a 3 lug lock between catch and lever, and serrations where your finger contacts the lever. The lever works only with the BAD-EBC catch in this kit. It does not fit mil-spec or other aftermarket catches, or the 308 version.
