Rosco AR-15 Bloodline Upper Receiver Assembly without BCG 5.56x45mm 16″ Barrel 15″ M-LOK Handguard Black

The Rosco AR-15 Bloodline Upper Receiver Assembly is a culmination of the performance and synchronization of Rosco barrels and accessories. The original goal was to supply folks with well-made barrels to improve their current platforms. After Rosco reached that marker, they then sought out the best accessories and tuned them to work perfectly with the barrels in a cohesive system. Ultimately, Rosco decided to bring their talents as shooters and gunsmiths to provide non-builders with a product that was a drop-in option.

Rosco URGs have every bit of Rosco 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 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 road map on which Rosco Manufacturing will never compromise.
