{"product_id":"fz-lightweight-bolt-carrier-group","title":"FailZero Lightweight Bolt Carrier Group – AR-15\/M16","description":"\u003cp\u003eThe FailZero Lightweight Bolt Carrier Group reduces reciprocating mass in your AR-15 or M16 platform, decreasing felt recoil and enabling faster cycling in competition or tactical applications. This BCG removes material from non-critical areas of the carrier while maintaining full-auto profile dimensions, making it compatible with standard AR-15 upper receivers and fire control groups. Shooters looking to reduce muzzle rise and improve split times often choose a lightweight BCG as a key component in tuned carbine builds.\u003c\/p\u003e\u003cp\u003eThe carrier and bolt are coated with FailZero's proprietary nickel boron finish, which provides permanent dry lubrication and extreme resistance to carbon fouling. This coating reduces friction and wear while simplifying cleaning—carbon wipes away with minimal solvent. The bolt is properly staked and MPI tested. Installation is drop-in for shooters familiar with AR-15 disassembly; no gunsmithing required. Gas system tuning may be necessary depending on your rifle's existing configuration, buffer weight, and ammunition.\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, M16\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 coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfile:\u003c\/strong\u003e Full-auto, lightweight design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in (gas system tuning may be required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Bolt carrier, bolt assembly, cam pin, firing pin, retaining pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FailZero","offers":[{"title":"Default Title","offer_id":47937942487295,"sku":"FZ-LW-BCG-01-NH","price":224.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1260819.jpg?v=1766499794","url":"https:\/\/doublestackstore.com\/products\/fz-lightweight-bolt-carrier-group","provider":"Double Stack Store","version":"1.0","type":"link"}
