This barrel features Faxon's Big Gunner profile—a mid-weight contour that balances accuracy with practical handling for extended range sessions and hunting applications. The 8.6 Blackout chambering delivers hard-hitting performance in a compact package, making this barrel ideal for suppressed builds or mid-range precision work where energy retention matters.\u003c\/p\u003e\u003cp\u003eMachined from 4150 steel with a QPQ nitride finish, this barrel offers corrosion resistance and extended service life. The 16\" length meets legal requirements for rifles while maintaining velocity suitable for both subsonic and supersonic ammunition. Faxon barrels are known for consistent manufacturing tolerances and compatibility with standard AR-10 upper receivers. Installation requires standard AR-10 barrel tools and headspace verification. This is a direct replacement for shooters building or upgrading AR-10 rifles chambered in 8.6 Blackout.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Rifle Barrel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 8.6 Blackout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 16\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfile:\u003c\/strong\u003e Big Gunner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 4150 Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e QPQ Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-10 Platform Rifles\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Faxon Firearms","offers":[{"title":"Default Title","offer_id":48535423516927,"sku":"FX10A863C16NGQ","price":226.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/3018950.jpg?v=1778982202","url":"https:\/\/doublestackstore.com\/products\/faxon-bbl-8-6blk-16-big-gunner","provider":"Double Stack Store","version":"1.0","type":"link"}
