JP Enhanced Reliability Spring Kit AR JPS3.5T

Designed for most Mil-spec AR stle trigger systems especiallg for use with 22LR riifles.

JP Enhanced Reliability Spring Kit

This spring kit will yield a 3.5-4.0 lb. trigger pull with JP Fire Control parts. This kit is intended for use with JP trigger parts and will not necessarily yield substantial change on standard AR-15 trigger components. 

Application: Use of this spring kit allows for use of ammunition with low-sensitivity primers such as those found in NATO-spec and various foreign-manufactured ammunitions, but in the case of large-frame ARs and duty/defense rifles, domestic-manufactured ammo is strongly recommended to ensure 100% ignition reliability.
 

Compatibility: This spring set will function with most any component-style AR fire control system. However, it will not function in our JPFC-M modular trigger.
