Northtech Defense starts with the hardest 416R stainless steel that has been through both heat treating and stress relief processes. The rifling is made by their unique five-cut method that has been shown to facilitate exceptional accuracy. The 1:8 twist and M4-style feed ramps are machined in for both accuracy and dependability. The barrel is fluted with precision to minimize the weight. Before any barrel is shipped out, it must pass a quality check with a master bolt face to ensure proper headspacing.
