DPMS AR-10 Bolt Catch Assembly

The DPMS AR-10 Bolt Catch Assembly (DPMS part no. DP51655128291) is a direct-fit replacement for the bolt catch on AR-10 pattern rifles, the part responsible for locking the bolt carrier group to the rear once the magazine runs dry. Keeping this part in good working order matters for both function and safety checks, since a worn or damaged bolt catch can fail to hold the bolt open or make it harder to confirm the rifle is clear. DPMS builds this assembly to factory specifications, making it a reliable choice for repairing or maintaining an AR-10 pattern rifle.
