{"product_id":"santan-ar15-enhncd-bcg-6mm-arc-blk","title":"San Tan Tactical Enhanced BCG 6mm ARC – AR-15 Platform","description":"\u003cp\u003eThe San Tan Tactical Enhanced Bolt Carrier Group is engineered specifically for 6mm ARC chamberings in AR-15 platform rifles. This BCG addresses the unique pressure curve and case dimensions of the 6mm ARC cartridge, providing reliable extraction and feeding that standard 5.56 bolt carrier groups may not consistently deliver. Shooters building or converting to 6mm ARC for precision or hunting applications will find this a purpose-built solution that supports consistent cycling across varied loads.\u003c\/p\u003e\u003cp\u003eConstructed from high-grade steel with a black finish, this enhanced BCG features proper headspacing geometry for 6mm ARC and strengthened components where needed. Installation is drop-in for AR-15 uppers chambered in 6mm ARC—no gunsmithing required. The enhanced design focuses on durability and extraction reliability rather than decorative features.\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 platform rifles chambered in 6mm ARC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-grade steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black\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":"San Tan Tactical","offers":[{"title":"Default Title","offer_id":47939761864959,"sku":"STTENHANCEDBCG6ARC","price":181.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1338395.jpg?v=1766546462","url":"https:\/\/doublestackstore.com\/products\/santan-ar15-enhncd-bcg-6mm-arc-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
