{"product_id":"fz-ar15-bcg-no-hammer-blk","title":"FailZero AR-15 Bolt Carrier Group (No Hammer) – Black EXO Coating","description":"\u003cp\u003eThe FailZero AR-15 Bolt Carrier Group delivers reduced friction and enhanced reliability through its proprietary EXO nickel-boron coating. This BCG is designed for shooters who want extended time between cleanings and smoother cycling without wet lubrication. The \"no hammer\" designation means this carrier does not include a firing pin, cam pin, or gas key screws—ideal for builders who already have these components or prefer to source them separately.\u003c\/p\u003e\u003cp\u003eMachined from mil-spec 8620 steel (carrier) and 9310 steel (bolt), the entire BCG receives a uniform black EXO coating that penetrates the metal surface for self-lubricating properties and corrosion resistance. The coating reduces carbon buildup and allows for dry operation in dusty or sandy environments. Installation is drop-in for any mil-spec AR-15 upper receiver. This BCG is intended for experienced builders familiar with AR-15 assembly and headspace verification.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Bolt Carrier Group (No Firing Pin\/Cam Pin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e Mil-Spec AR-15\/M16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 8620 Steel Carrier, 9310 Steel Bolt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black EXO Nickel-Boron Coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (Gunsmithing Knowledge Recommended)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Bolt Carrier, Bolt, Extractor, Ejector (No Firing Pin, Cam Pin, or Gas Key Hardware)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FailZero","offers":[{"title":"Default Title","offer_id":47937920827647,"sku":"FZ-AR15-01-NH-BLACK","price":156.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1260785.jpg?v=1766499722","url":"https:\/\/doublestackstore.com\/products\/fz-ar15-bcg-no-hammer-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
