For Smooth, Light Trigger Pull & Reliable Ignition
Precision-calibrated springs give produce a consistent pull on a stock JP M15 rifle trigger, while preserving ignition reliability with U.S.-manufactured ammunition. JPS3.5T produces 3.5 to 4 lb. trigger pull. Can also be used with properly prepared (instructions included) mil-spec trigger/hammer components to produce a 4- to 5-lb. pull with a smooth “roll off” feel and good control. The JPS4.0 spring kit produces a 4 to 4.5 lb. trigger pull.
