The Rosco Sauce Pack bundles were created after direct requests from Rosco's customers to provide them with the key components needed for their carbine/pistol builds at a great combined price. The result is a hand-picked list of parts that will produce results right out of the box. All parts within these kits are designed to synchronize together and create an un-interrupted system that will bring every individual component to its peak performance level. The perfect marriage of all their available Bloodline accessories and their in-house made barrels will make for the ultimate combo in performance and cost savings. RSR -
