AR-15 Bolt Catch Plunger

Features

1. Mil-Spec Dimensions — Manufactured to military specifications for a drop-in fit in any standard AR-15, M4, or M16 lower receiver.
2. Hardened Steel Construction — Built from heat-treated steel to resist wear from repeated bolt catch engagement and release cycles.
3. Bolt Catch Assembly Component — Seats inside the bolt catch and rides against the detent spring to provide proper tension on the bolt catch lever.

5. Direct Factory Replacement — Ideal for repairing worn or lost plungers, completing a parts kit, or finishing a stripped lower receiver build.
6. Compatible With Standard Bolt Catch Springs — Works with any mil-spec bolt catch spring and roll pin, no fitting or modification required.
7. Compact Spare-Part Footprint — Small enough to keep several on hand in your range bag, armorer's kit, or spare-parts box.
8. AR-15 / M4 / M16 Platform — Fits the full family of mil-spec AR-pattern lowers from major manufacturers.
