The Noveske Infidel Barrel (brand part no. 07000052) is a 13.7-inch AR-platform barrel chambered in .223 Rem/5.56 NATO, machined from 416R stainless steel for a compact build that still carries Noveske’s Match-grade standards. Noveske Rifleworks hand-polishes the proprietary Noveske Match chamber and cuts a 1:7 twist rate, pins a low-profile .750-inch gas block in place, and finishes the muzzle with 1/2×28 threads and a 60-degree crown. An M4-style barrel extension with extended feed ramps supports reliable feeding, and each barrel ships individually serialized with a gas tube matched to its gas system. Among AR barrels, this Infidel barrel favors builders who want a shorter, carbine-length Noveske barrel for a compact, maneuverable rifle.
