JP Enterprises AR-15 Enhanced Ignition Trigger Spring Kit

The JP Enterprises enhanced ignition spring kit includes a trigger spring, a disconnector spring and JP's red extra power hammer spring. With JP fire control parts it gives a trigger pull of 3.5 to 4.0 lb. The kit is meant for JP trigger parts and will not necessarily make a big change on standard AR-15 trigger components.

The red hammer spring is the reason to buy it. JP calls it the minimum hammer spring for military type ammunition and other hard primers, where a lighter spring can leave you with light strikes.
