This BCG delivers reliable cycling and extraction with a two-tone finish that combines a dark earth carrier with a black bolt for visual distinction during maintenance and inspection. It's built to meet or exceed military specifications for shooters who demand consistent performance without unnecessary frills.\u003c\/p\u003e\u003cp\u003eThe carrier is coated in a durable dark earth finish, while the bolt features a black nitride or phosphate coating for corrosion resistance and ease of cleaning. The KSPEC BCG is machined from 8620 steel (carrier) and 9310 steel (bolt), both standard materials for mil-spec carriers. Gas key is properly staked. This is a drop-in replacement for standard AR-15 platforms—no fitting or gunsmithing required.\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, 5.56 NATO, .223 Remington\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 Dark Earth Carrier, Black Bolt\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 Bolt Carrier Group (Carrier, Bolt, Cam Pin, Firing Pin, Retaining Pin)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KAK Industry","offers":[{"title":"Default Title","offer_id":47938714927359,"sku":"KAK425-0512-003","price":179.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/4479429.jpg?v=1766526327","url":"https:\/\/doublestackstore.com\/products\/kak-kspec-ar15-bcg-556-de-clp-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
