The Noveske Infidel Barrel (brand part no. 07000071) is a 13.7-inch 5.56mm stainless barrel from one of the most respected names in AR accuracy. Noveske Rifleworks machines the Infidel from 416R stainless steel with a 1:7 twist and a hand-polished proprietary Noveske Match chamber, then fits a pinned .750-inch low-profile gas block, an M4-style barrel extension with extended feed ramps, 1/2×28 muzzle threads, and a 60-degree crown. Each barrel is individually serialized and includes a gas tube matched to its gas system. Among rifle barrels, the Infidel favors builders who want match-grade accuracy in a compact configuration.
