JP Rifles Reduced Power JPS3.5 AR-15 Spring Kit
The JPS3.5 spring kit will yield a 4.0-4.5 lb. pull with standard AR-15 trigger parts and 3.0-3.5 lb. with JP trigger parts. These custom-produced springs are the same ones JP Rifles uses with their JP Fire Control components to achieve a reliable 3-lb. trigger setup with their proprietary sear geometry. The JPS3.5 can also be used with properly prepared Mil-spec trigger/hammer components and a good anti-seize grease to achieve a usable 4- to 5-lb. trigger. The standard trigger and hammer are made of 8620 alloy steel with a case-hardened surface that is over 60R in hardness. However, this hard outer layer is very thin, and no change in the geometry of the sear surface or hammer notch is possible without cutting through to the inner ductile core of the parts. Once you cut through the hard case, the parts are of no use.
