The Rosco Sauce Pack + Upper Receiver Group (part no. SP-PB-20-223-BCG-GTR) bundles a matched barrel, bolt carrier group, and gas tube with an upper receiver group, giving builders the core of a .223-chambered carbine or pistol build in one purchase. ROSCO MANUFACTURING threads the barrel 1/2×28 and synchronizes every included part to work together rather than requiring separate part-matching.
