Rosco Bloodline Sauce Pack Bundle, 11.5in 5.56, Barrel/BCG/Gas Tube/Gas Block

The Rosco Manufacturing Bloodline Sauce Pack Barrel (brand part no. SP-BL-115-556-BCG-GTC-NGB-001) bundles an 11.5-inch 5.56 NATO Bloodline barrel with a matched bolt carrier group, gas tube, and gas block, threaded 1/2×28 at the muzzle for a compensator or other muzzle device. At 11.5 inches, this barrel falls below the 16-inch minimum for a rifle-configured build, meaning it’s intended for a pistol-configured AR (no shoulder stock) or for use on a properly NFA-registered short-barreled rifle. Rosco applies the same Bloodline manufacturing standard to this shorter length as its longer barrels, aimed at close-quarters builds that need compact handling.
