Bloodline 14.5” M4 5.56 NATO (Mid-Length)

14.5” M4 5.56 NATO Bloodline Barrel (Mid-Length): This 14.5” M4 5.56 NATO 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. ALL NFA RULES APPLY!
