• Trigger pull weight of 4.0-4.5 lbs. with standard AR-15 trigger parts
• 3.0-3.5 lb. with JP trigger parts. 
• Much lighter than standard Mil-Spec trigger pull
• For use with reloaded or domestic ammuntion with high sensitivity primers

This spring kit is intended to be used with both JP Enterprises fire control parts or Mil Specification parts. With a Mil-Spec trigger, disconector, hammer, and JP springs you will get an end trigger pull weight of 4.0-4.5 lbs. With JP parts you will yeild a pull weight of 3.0-3.5 lbs. Either way there is a substantial difference in pull weight when compared to almost any complete Mil-Spec trigger assembly. 

JP advises: These spring will not reliably ignite NATO spec primers, and are intended for recreational and competition types of shooting only! These springs should not be installed in any rifle used for defense or duty applications or any AR-10 type rifle.
