This YHM 14.5″ M4 5.56 NATO Mid-Length barrel was designed around the USASOC specs for an Improved Upper Receiver Group. The longer, mid-length 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!
