Rosco Bloodline Sauce Pack Features The Rosco Manufacturing Bloodline Sauce Pack was developed directly from customer requests for a curated set of key components needed to complete a carbine or pistol build without sourcing each part separately. Every part included in the pack is selected to synchronize with the others creating an uninterrupted system where each individual component performs at its intended peak level rather than being mismatched. This approach saves builders the time and guesswork of researching compatible parts from multiple sources. The 14.5 inch barrel at the heart of the pack is chambered in 5.56 NATO a widely used caliber for AR pattern builds. Constructed from chrome moly steel with a black nitride finish the barrel offers strong durability and corrosion resistance for repeated firing. A 1 in 7 inch twist rate is well suited to stabilizing a wide range of 5.56 bullet weights giving builders flexibility in ammunition choice. The barrel is threaded 1/2x28 the standard pattern for 5.56 muzzle devices and weighs 26.34 oz on its own. For builders looking for a hand-picked set of parts designed to work together out of the box the Rosco Manufacturing Bloodline Sauce Pack is available for sale at GrabAGun.
