The Faxon Match 16-Inch .338 ARC AR15 Barrel (brand part no. 15B338A8C16NGQ-5R-NP3) is a 16-inch barrel chambered in .338 ARC, part of Faxon Firearms’ Match series built for accuracy-focused AR15 uppers. The .338 ARC cartridge is designed to deliver heavy-for-caliber performance out of standard AR15-length platforms, and Faxon’s Match series barrels are built to let that performance show on target. At 16 inches, this barrel keeps an AR15 upper compact and maneuverable while still giving the .338 ARC round room to develop velocity. It is a direct option for shooters building a dedicated .338 ARC upper for hunting or precision work.
