{"product_id":"fz-6-8spc-bcg-no-hammer-nib","title":"FailZero 6.8 SPC Bolt Carrier Group (No Hammer) – NiB Coated","description":"\u003cp\u003eThe FailZero 6.8 SPC Bolt Carrier Group delivers a drop-in replacement or upgrade for AR-15 pattern rifles chambered in 6.8 SPC. Built with proprietary Nickel Boron (NiB) coating, this BCG reduces friction and carbon fouling compared to standard phosphate finishes, making post-range cleaning faster and easier. Designed for shooters who need reliable cycling in a harder-hitting intermediate caliber, this bolt carrier group is built to handle the increased chamber pressures of 6.8 SPC.\u003c\/p\u003e\u003cp\u003eThe carrier and bolt are machined from mil-spec materials and feature FailZero's NiB finish inside and out, including the gas key. Installation is straightforward for anyone familiar with AR-15 maintenance—no gunsmithing required. This version does not include a firing pin, cam pin, or retaining pin, allowing you to reuse existing components or select aftermarket parts. The permanently staked gas key and proper headspacing ensure reliable function across a wide range of ammunition types.\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 AR-15 pattern rifles in 6.8 SPC\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 Nickel Boron (NiB) 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 Carrier, bolt, and gas key (no firing pin, cam pin, or retaining pin)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FailZero","offers":[{"title":"Default Title","offer_id":47937893990655,"sku":"FZ-68SPC-01-NH","price":171.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1260768.jpg?v=1766499460","url":"https:\/\/doublestackstore.com\/products\/fz-6-8spc-bcg-no-hammer-nib","provider":"Double Stack Store","version":"1.0","type":"link"}
