The Rosco K9 Sauce Pack (brand part number SP-K9-1395-556-BCG-GTM-NGB-001) bundles a 13.95-inch barrel chambered in 5.56x45mm NATO/.223 Remington with a matched bolt carrier group, gas tube, and gas block, created after customers repeatedly asked Rosco to package the key parts needed for a project at one combined price. Rosco hand-picks every part in the kit so the pieces synchronize together as a matched system, and the barrel ships threaded 1/2-28 for a compensator or thread protector.
