Noveske Rifleworks is well know for state of the art manufacturing processes. These barrels maintain accuracy and reliability. The chamber is slightly modified from the NATO-Spec to improve bullet hook-up in the throat, while keeping to reliable properties of the NATO body dimensions. The result is Noveske proprietary chambering. The steel used is a type of 416R and hardened to about 30 HRC prior to any machining. These barrels are button rifled with Noveske proprietary 7 PT button.
