The Rosco Purebred URGs are a culmination of the performance and synchronization of our barrels and accessories. Our original goal was to supply folks with well-made barrels to improve their current platforms. After we reached that marker, we then sought out the best accessories and tuned them to work perfectly with our barrels in a cohesive system. Ultimately, we decided to bring our talents as shooters and gunsmiths to provide non-builders with a product that was a drop-in option.
Our URGs have every bit of our DNA in them- from the years of turning barrels (OEM & Commercial), to the hand-picked support components, and the many hours of working over a bench. All the details that are often disregarded by other manufacturers are the starting points to these upper receiver groups. Headspace, correct torques, gas port/ gas block alignment, and lapped surfaces are the bricks that create a path to cornerstone performance. Those items are not just a hit-list of tasks for these URGs, it’s a roadmap we will never compromise on.
