{"product_id":"spikes-m16-bolt-carrier-group-blk","title":"Spike's Tactical M16 Bolt Carrier Group – Black Phosphate","description":"\u003cp\u003eThe Spike's Tactical M16 Bolt Carrier Group is a mil-spec replacement BCG designed for AR-15 and M16 platform rifles. The full-auto M16 profile carrier provides increased mass over semi-auto BCGs, which helps improve reliability and reduces felt recoil in semi-automatic fire. This BCG is a direct replacement for worn or damaged carriers and serves as a quality spare for shooters who maintain multiple rifles or log high round counts.\u003c\/p\u003e\u003cp\u003eMachined from 8620 steel with a black phosphate finish, this carrier group is treated with a properly staked gas key and includes a complete bolt assembly with extractor and ejector. The black phosphate coating provides corrosion resistance and reduces friction for smoother cycling. Installation is drop-in for anyone familiar with AR-15 field stripping—no gunsmithing required.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e M16 Profile Bolt Carrier Group\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, M16, M4 (5.56\/.223)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 8620 Steel Carrier, Carpenter 158 Steel Bolt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Phosphate\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 Complete BCG with gas key, bolt, cam pin, firing pin, retaining pin, extractor, ejector, and springs\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Spike's Tactical","offers":[{"title":"Default Title","offer_id":47938905047295,"sku":"SPKST5BG01","price":139.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1336344.jpg?v=1766536210","url":"https:\/\/doublestackstore.com\/products\/spikes-m16-bolt-carrier-group-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
