Battle Arms Development EKG Enhanced AK Trigger Kit

The Battle Arms Development EKG is a three-piece AK trigger kit consisting of a hammer, trigger, and disconnector, designed for AK-47 and AK-74 pattern rifles. It is intended as a replacement fire-control group for owners of standard production AK-style firearms.

The kit is made from thru-hardened steel with a specified hardness of HRC 42-45 and a black phosphate finish. The hammer uses enhanced geometry intended to reduce the hump felt when charging the rifle, and the trigger features a comfortable shoe and a single-hook design. According to the description, the thru-hardened construction is meant to limit internal wear and mushrooming at the back of the carrier.

The kit includes the hammer, trigger, disconnector, disconnector spring, and axis pin sleeve. Hammer and trigger springs are not included and must be sourced separately. The parts are listed as made in the USA for 922(r) compliance.
