Our 5.56 NATO Mid Length Barrel is constructed from mil-spec 4150 chrome vanadium steel. In addition, it features 5R rifling with a 1:8 twist rate. As a result of the Patented E² extraction technology, you can expect extractor life to drastically increase. All barrels are nitride heat treated, which above all, greatly increases surface hardness and corrosion resistance.
