The Rosco “Sauce Pack” bundles were created after direct requests from our 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 our available Bloodline accessories and our in-house made barrels will make for the ultimate combo in performance and cost savings.

Our Purebred sauce packs feature our hard-use barrels (from the namesake category) and the accessories needed to provide the consumer with a complete ignition system for their Duty/ Defense builds. Each Purebred “Sauce Pack” features a Purebred barrel, Bloodline BCG (5.56/.300 BLK), Bloodline Gas Block (Non-Adjustable), and a Bloodline Gas Tube (Pistol, Carbine, Mid-Length, or Rifle). The parts are all designed to work perfectly when paired together and are designed to maximize the performance of each component, collectively!

    Used this as the soul for my brother-in-law’s coyote gun I built this winter. Consistently groups 10 rounds Freedom 62gr fmj 1.5-2 inches at 100yds, hand full of 3 round dime sized groupings with same. At just past 2 am the morning after zeroing and ranging out, he freehand dropped a yote with a headshot just over 75yds with Winchester 64gr xp. Needless to say we are both very impressed and I’m looking forward to making another precision build with this barrel.
