This 16″ M4 5.56 NATO Mid-Length barrel was built to meet the USASOC specs for an Improved Upper Receiver Group, with a touch of the Rosco style as well. The longer gas system ensures a smoother gas flow, resulting in controlled dwell times. This combination provides a good balance of speed and performance.
