The \u003cstrong\u003eBig Gunner\u003c\/strong\u003e contour is engineered to dampen barrel harmonics and support long, heavy projectiles, while still keeping the overall weight manageable on a precision \u003cstrong\u003eAR-10\u003c\/strong\u003e build.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe bore is cut with \u003cstrong\u003e5R button rifling\u003c\/strong\u003e at a \u003cstrong\u003e1:8\u003c\/strong\u003e rate of twist, a combination chosen for the \u003cstrong\u003e6.5 Creedmoor\u003c\/strong\u003e cartridge.

The barrel is finished in \u003cstrong\u003eNP3\u003c\/strong\u003e, a nickel-PTFE coating that resists corrosion, sheds fouling, and makes routine cleaning noticeably easier.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eAt \u003cstrong\u003e18 inches\u003c\/strong\u003e in length, this \u003cstrong\u003eMatch Series\u003c\/strong\u003e barrel is set up for a \u003cstrong\u003erifle-length gas system\u003c\/strong\u003e on the standard \u003cstrong\u003eAR-10 \/ LR-308\u003c\/strong\u003e pattern, making it a straightforward drop-in component for a precision target rifle, a long-range hunting platform, or a custom big-bore AR-10 build.\u003c\/span\u003e\u003c\/p\u003e","brand":"Faxon Firearms","offers":[{"title":"Default Title","offer_id":55324402024770,"sku":"FF22065","price":302.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/alt_32a58844-2e89-43c3-a8dc-9ef8d450071b.jpg?v=1785151493","url":"https:\/\/centerfiresystems.com\/products\/faxon-firearms-match-series-6-5-creedmoor-18-1-8-5r-big-gunner-ar-10-barrel-np3","provider":"Centerfire Systems","version":"1.0","type":"link"}
