The JP Enterprises Service Rifle Spring Kit is a dedicated AR-15 fire control upgrade designed to deliver a clean, competition-legal 4.5 lb trigger pull when paired with JP trigger components. Built from high-tensile spring wire, the included hammer and trigger springs are tuned to enhance reliability and improve the feel of the trigger break for service rifle, law enforcement, and general range use.

This kit is ideal for shooters who want a consistent, rule-compliant trigger weight without sacrificing dependable cycling. While it performs best with JP fire control parts, it can also be used with many Mil-Spec or aftermarket components to refine trigger characteristics. Whether you are focused on High Power competition or simply want a more predictable trigger on your AR-15, this spring kit reflects JP Enterprises’ reputation for thoughtful engineering and precision-focused innovation.
