This small but critical component prevents firing pin migration during the cycling process. Shooters replace this pin when the original is lost during cleaning, damaged, or as part of a routine BCG maintenance overhaul. KNS Precision manufactures this pin to MIL-SPEC dimensions for reliable function in all AR-15 and M16 bolt carrier groups.\u003c\/p\u003e\u003cp\u003eMachined from heat-treated steel with a corrosion-resistant finish, this retaining pin installs in seconds without tools or modification. Simply insert through the bolt carrier cross-hole to capture the firing pin. This is a drop-in component that requires no gunsmithing. Keep spares on hand—losing this pin during field maintenance renders the rifle inoperable until replaced.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Firing Pin Retaining Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, M16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-Treated Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Corrosion-Resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e (1) Firing Pin Retaining Pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KNS Precision, Inc.","offers":[{"title":"Default Title","offer_id":47943822835967,"sku":"KNSPERMA","price":10.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1275394.jpg?v=1766602286","url":"https:\/\/doublestackstore.com\/products\/kns-ar15-firing-pin-retaining-pin","provider":"Double Stack Store","version":"1.0","type":"link"}
