AR-15 Magazine Catch Spring
The United Defense AR-15 Magazine Catch Spring is a mil-spec replacement spring for the magazine catch assembly on AR-15, M4, and M16 pattern rifles and pistols. Made from hardened spring steel, it delivers the correct tension to keep magazines locked in place and drop free cleanly on release. Drops straight into any standard AR-15 lower receiver with no fitting required. A smart pickup for anyone building a lower from a parts kit, refreshing a high-round-count rifle, or stocking an armorer's spares box.
