The full-auto carrier provides increased mass for reliable cycling with a wider range of ammunition and suppressor use, even in semi-auto-only firearms. This lightweight variant reduces reciprocating mass compared to standard BCGs, potentially improving felt recoil and cycling speed while maintaining durability for high round counts.\u003c\/p\u003e\u003cp\u003eMachined from 8620 steel with a carpenter 158 steel bolt, this BCG features a phosphate finish for corrosion resistance and proper lubricity. The gas key is properly staked per mil-spec standards. Installation is drop-in for any mil-spec AR-15 upper receiver—no fitting or gunsmithing required. Includes bolt, carrier, cam pin, and firing pin.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e M16 Full-Auto Bolt Carrier Group\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, M16, M4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarrier Material:\u003c\/strong\u003e 8620 Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Material:\u003c\/strong\u003e Carpenter 158 Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e 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 Bolt, Carrier, Cam Pin, Firing Pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Spike's Tactical","offers":[{"title":"Default Title","offer_id":47938905440511,"sku":"SPKST5BG05","price":232.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1336349.jpg?v=1766536282","url":"https:\/\/doublestackstore.com\/products\/spikes-m16-bolt-carrier-group-lw","provider":"Double Stack Store","version":"1.0","type":"link"}
