Rosco Manufacturing 8.2″ (300 BLK) Bloodline Series AR-15 barrel


In this video we highlight the capabilities of our 8.2″ 300 BLK Bloodline series barrel. As with all of our Bloodline series barrels this one is made out of 4150 CMV and then the barrel (and extension) are treated in a Salt Nitride Bath for corrosion resistance and extended performance.We have also optimized operational reliability for platforms that run suppressed/ un-suppressed by sizing the gas port diameter appropriately.
