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.

This 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.
 

Application: Use of this spring kit requires the use of US-manufactured (domestic) ammunition or reloads with domestic (non-NATO spec) primers as ignition reliability will be reduced with hard, low-sensitivity primers such as those found in NATO-spec and various foreign-manufactured ammunitions. These springs are for recreational or competition shooting only and should not be installed in any rifle used for defense or duty applications or any AR-10 type rifle.
