Rosco Manufacturing 11.5″ (5.56) Bloodline Series AR-15 barrel
In this video we highlight the capabilities of our 11.5″ 5.56 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.
I have ordered the bloodline in 11.5 and I am looking at putting a riflespeed adjustable gas block on it, I can’t seem to find specs on the barrel besides .750 gas journal… how long is the barrel from the gas block to the threads? I would like to order my gas block now so I don’t have to wait but I need to know how long of an adjustment knob to get. Any help would be great! Will a 3.3” riflespeed work?
