{"product_id":"bootleg-5-56-nitride-bcg-complete","title":"Bootleg 5.56 Nitride BCG Complete – AR-15\/M16 Platform","description":"\u003cp\u003eThe Bootleg 5.56 Nitride BCG is a complete bolt carrier group engineered for reliable function in AR-15 and M16 platform rifles chambered in 5.56 NATO\/.223 Remington. This BCG handles the core cycle of operation—feeding, chambering, locking, firing, extraction, and ejection—making it a direct replacement for factory or worn components. Shooters upgrade to aftermarket BCGs for improved surface hardness, easier cleaning, or as a spare to keep their rifle running.\u003c\/p\u003e\u003cp\u003eThe bolt carrier, bolt, gas key, cam pin, and firing pin are treated with a black nitride finish, which increases surface hardness and corrosion resistance while reducing friction. Nitride penetrates the metal rather than coating the surface, resulting in a finish that won't flake or chip. The gas key is properly staked per mil-spec standards. This is a drop-in component for standard AR-15 lower and upper receivers—no gunsmithing required, though basic familiarity with AR-15 disassembly is recommended for installation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Bolt Carrier Group (BCG)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, M16 (5.56 NATO\/.223 Rem)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Nitride\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 Bolt Carrier, Bolt Assembly, Cam Pin, Firing Pin, Gas Key (Staked)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bootleg","offers":[{"title":"Default Title","offer_id":47937367998719,"sku":"BOOTBP-C15-BCG","price":121.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1263261.jpg?v=1766487087","url":"https:\/\/doublestackstore.com\/products\/bootleg-5-56-nitride-bcg-complete","provider":"Double Stack Store","version":"1.0","type":"link"}
