{"product_id":"fz-6-5gren-bcg-no-hammer-nib","title":"FailZero 6.5 Grendel Bolt Carrier Group (No Hammer) – Nickel Boron Coated","description":"\u003cp\u003eThe FailZero 6.5 Grendel Bolt Carrier Group delivers enhanced reliability and reduced maintenance for AR-15 platform rifles chambered in 6.5 Grendel. Designed for the higher bolt thrust of the 6.5 Grendel cartridge, this BCG features proper headspacing and bolt face dimensions to ensure safe, consistent cycling with match-grade ammunition. This version does not include a hammer, making it ideal for replacement or custom builds where you're retaining your existing fire control group.\u003c\/p\u003e\u003cp\u003eThe entire BCG is treated with FailZero's proprietary nickel boron (NiB) coating, which creates an extremely hard, self-lubricating surface that reduces friction and resists fouling. This finish improves bolt cycling smoothness, simplifies cleaning, and extends service intervals—particularly valuable during high-volume shooting sessions. Installation is drop-in for any mil-spec AR-15 upper receiver, though headspace verification is recommended when installing any new bolt. The nickel boron coating provides excellent corrosion resistance and maintains its low-friction properties even under adverse conditions.\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 chambered in 6.5 Grendel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel carrier and bolt\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 (headspace verification recommended)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Bolt carrier, bolt assembly, cam pin, firing pin, firing pin retaining pin (no hammer included)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FailZero","offers":[{"title":"Default Title","offer_id":47937892286719,"sku":"FZ-65-GRENDEL-01-NH","price":171.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2863556.jpg?v=1766499428","url":"https:\/\/doublestackstore.com\/products\/fz-6-5gren-bcg-no-hammer-nib","provider":"Double Stack Store","version":"1.0","type":"link"}
