The Magpul MIAD/MOE Bolt & Firing Pin Core is an Internal core unit for the MIAD®, MOE®, and MOE-K2® Grips*. Designed to hold one (1) standard AR15 / M4 complete bolt and firing pin (not included). Core provides water resistant storage. Magpul grip cores allow you to keep mission critical components with your primary at all times. From spare bolts and firing pins, to batteries (CR123, AA or AAA), lube, grease, hot sauce or Jack, your mission can dictate your core. Firing pin and bolt not included. For CR123 Core, check here. For AA/AAA Core, check here. Platform: AR10, AR15, M4, M16, M110, SR25 *NOTE: The Bolt & Firing Pin Storage Core is not recommended for use with the MOE ® or MOE-K2 Grips due to its slightly smaller internal dimensions required by the rubber overmolding.
