Upgrade your Kalashnikov with Timney's AK-47 Trigger. It features a curved trigger shoe and an exceptionally smooth, crisp, single-stage pull that breaks cleanly at 3.5 pounds. It is easily installed thanks to its 100% drop-in cassette style design, eliminating the need for a gunsmith. The AK-47 Trigger utilizes an adjustable screw to match the rifle's safety lever, allowing the trigger to fit multiple AK variants including: Bulgarian, Chinese, East German, Hungarian, Korean, Polish, Romanian, Russian, Serbian, U. S.-made, and Yugoslavian AKM’s. Additionally, the AK-47 Trigger is secured in the housing using four set screws that mechanically bind the trigger to the receiver, similar to Timney's AR offerings.
