Rosco Manufacturing BL-16-GVT-556-7-M Bloodline 5.56 NATO 16″ Nitride 4150 CMV Barrel

This 16″ M4 5.56 NATO Bloodline Barrel Mid-Length barrel was designed around the USASOC specs for an Improved Upper Receiver Group with a little bit of the Rosco touch as well. The longer gas system allows for a smoother gas curve which leads to managed dwell times. This combo creates a great balance of speed and performance.
