Unlike standard 5.56\/.223 BCGs, this carrier group features a bolt machined specifically for the 6.5 Grendel case head diameter, ensuring reliable extraction and ejection with proper brass support.\u003c\/p\u003e\u003cp\u003eThe bolt is manufactured from 9310 steel, a high-strength alloy known for superior fatigue resistance compared to standard Carpenter 158 steel. The entire assembly features a black nitride finish for corrosion resistance and reduced friction. This is a drop-in component for mil-spec AR-15 upper receivers chambered in 6.5 Grendel—no gunsmithing required. Carrier includes staked gas key and extractor spring.\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 6.5 Grendel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Material:\u003c\/strong\u003e 9310 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 Complete bolt carrier group with gas key, extractor, ejector, cam pin, and firing pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Aero Precision","offers":[{"title":"Default Title","offer_id":47944019673343,"sku":"APRH100725C","price":172.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2960756.jpg?v=1766612751","url":"https:\/\/doublestackstore.com\/products\/aero-ar15-6-5gren-bcg-w-9310-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
