AR-15 Disconnector
The United Defense AR-15 Disconnector is a mil-spec replacement fire control component for AR-15 and AR-10 lower receivers. Machined from hardened steel and finished in corrosion-resistant phosphate, it captures the hammer on trigger reset to ensure proper semi-automatic function and prevent hammer follow. Precision-ground engagement surfaces and a reamed trigger pin hole deliver a clean, consistent reset round after round. A solid choice for AR builders, armorers, and shooters who need a dependable spare or replacement for a worn or lost disconnector.
