AR-15 Disconnector Spring
The United Defense AR-15 Disconnector Spring is a mil-spec replacement spring for the fire control group of any standard AR-15, M4, or M16 pattern rifle. Small, often overlooked, and absolutely critical, this spring sits between the disconnector and the trigger to provide the tension needed for the disconnector to reset against the hammer hook after each shot. Wound from hardened spring steel to GI dimensions, it drops in without fitting and restores reliable semi-auto function. Keep one in your spare parts kit, your range bag, or your armorer's bench — because losing one mid-build will stop you cold.
