The Rosco Sauce Pack bundles an in-house Rosco barrel with the parts that make it run, so a short .300 Blackout AR-15 build starts with components chosen to work together. The 10.50" heavy profile barrel runs a pistol-length gas system with a .750 gas block journal and a 1:7 twist rate.
Rosco designed this configuration for suppressed SBR and AR pistol use. The muzzle is threaded 5/8x24 for a can or muzzle device, an 11-degree crown protects accuracy, and a nitride finish adds corrosion and wear resistance. The included gas block, gas tube and bolt carrier group complete the core of the upper.
