This hammerless design is compatible with firearms that do not require a traditional hammer interface, streamlining the BCG profile for reliable cycling in dedicated 9mm platforms. FailZero's proprietary EXO coating over black nitride ensures consistent performance with reduced friction and fouling buildup.\u003c\/p\u003e\u003cp\u003eConstructed from mil-spec steel with black nitride treatment, this BCG features FailZero's nickel boron EXO coating on critical wear surfaces. The coating provides self-lubricating properties and corrosion resistance. This is a drop-in component for compatible 9mm AR lowers, though proper headspacing and function testing are required after installation. Includes bolt, carrier, cam pin, and firing pin.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Bolt Carrier Group\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e 9mm AR-pattern pistols and carbines (hammerless systems)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Mil-spec steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black nitride with EXO nickel boron coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in (headspacing verification and function testing required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Bolt, carrier, cam pin, firing pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FailZero","offers":[{"title":"Default Title","offer_id":47937899856127,"sku":"FZ-9MM-NITRIDE-BCG","price":164.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2139034.jpg?v=1766499626","url":"https:\/\/doublestackstore.com\/products\/fz-9mm-bcg-no-hammer-blk-nitride","provider":"Double Stack Store","version":"1.0","type":"link"}
