Expo Arms AR-15 Disconnector Spring - Semi Auto

The small spring that keeps your AR-15 trigger from following the hammer — and keeps you on the right side of the law. The Expo Arms AR-15 Disconnector Spring provides the consistent upward tension on the disconnector that prevents unwanted hammer follow or double-fire conditions, machined to mil-spec dimensions for direct drop-in compatibility with standard AR-15 fire control groups.

The Expo Arms AR-15 Disconnector Spring is a mil-spec replacement disconnector spring for standard semi-automatic AR-15 fire control groups, providing the consistent tension on the disconnector required to maintain proper hammer and sear interaction.

Three features make this a reliable spare part and repair component. Mil-spec dimensions ensure direct compatibility with all standard AR-15 fire control groups without fitting or modification, providing a true drop-in replacement that installs in minutes. High-quality spring steel construction provides the durability and consistent spring rate required at a component that cycles with every trigger pull across the service life of the firearm — a spring that loses rate over time degrades trigger feel and disconnector function. The disconnector spring is among the most commonly replaced small parts in an AR-15 fire control group and one of the most logical items to keep in a spare parts kit, particularly for high-volume shooters and armorers who maintain multiple rifles.
