Product Summary
The JP Enterprises Duty AR-15, AR-10 Trigger Spring Kit provides a 4.0 to 4.5 lb. trigger pull when used with JP Fire Control parts. This kit is specifically designed for AR-style .308 rifles and includes a red-coded hammer spring, a yellow-coded trigger return spring, and a disconnector spring. It is engineered to allow for the use of ammunition with low-sensitivity primers, such as NATO-spec and various foreign-manufactured rounds. While it enhances versatility with different ammo types, domestic-manufactured ammunition is strongly recommended for duty or defense rifles to ensure 100% ignition reliability.
