ALL NFA RULES APPLY! Rosco 5.56 (NATO) barrels are made to meet the needs of modern carbine shooters. Rosco is a long way from your daddy's Sporter AR, and those specs simply won't suffice anymore. From properly managing dwell times for SBRs, to running suppressed, or setting up a balanced patrol carbine, Rosco has incorporated your needs into its engineering. Rosco has achieved this by selecting the right twist rates, gas port diameters, and barrel materials appropriate for each barrel type.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul class=\"list-group css-columns-2 with-bullets\"\u003e\n\u003cli class=\"list-group-item\"\u003eBarrel Length: 11.5\"\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eBarrel Weight: 20.82 Oz\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eBarrel Material: 4150 CMV\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eBarrel Caliber: 5.56\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eBarrel Profile: M4\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eTwist: 1:7\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eBarrel Thread: 1\/2X28\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eGas Block Size: .750\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eGas System Length: Carbine\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eBarrel Crown: 11 Degree\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eBarrel Finish: Nitride\u003c\/li\u003e\n\u003cli class=\"list-group-item\"\u003eBarrel Extension Finish: Nitride\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Elias Defense Group","offers":[{"title":"Default Title","offer_id":43873247199341,"sku":"ROSBL-115-M4-556-7-C","price":137.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2023\/0765\/files\/C0262040-E3F4-476B-8250-A230F7E628B5.jpg?v=1768324926","url":"https:\/\/eliasdefensegroup.com\/products\/rosco-bloodline-11-5-barrel","provider":"Elias Defense Group","version":"1.0","type":"link"}
