Designed to improve reliability and longevity over standard mil-spec firing pins, this upgrade addresses wear and fouling issues that can cause misfires or light primer strikes in high-volume shooting environments. The NIB-X coating significantly reduces friction and carbon buildup, making post-range cleaning faster and extending maintenance intervals.\u003c\/p\u003e\u003cp\u003eConstructed from hardened steel and finished with WMD's proprietary Nickel Boron-based NIB-X coating, this firing pin offers exceptional lubricity and corrosion resistance. The self-lubricating surface means less oil retention and cleaner operation. Installation is drop-in—no fitting or gunsmithing required. Simply remove your bolt carrier group, swap the firing pin, and reassemble. Compatible with mil-spec AR-15 bolt carrier groups.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Firing Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 (5.56 NATO\/.223 Remington)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e NIB-X (Nickel Boron-Based Coating)\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 Firing Pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WMD Guns","offers":[{"title":"Default Title","offer_id":47939838968063,"sku":"WMDNIBXFP","price":13.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5584903.jpg?v=1766548374","url":"https:\/\/doublestackstore.com\/products\/wmd-nib-x-firing-pin-5-56","provider":"Double Stack Store","version":"1.0","type":"link"}
