Product Info for Faxon Firearms Match Series AR-15 338 ARC Threaded Barrel

The Gunner profile is a blend of two of the best performing profiles of all time, Gov't and Pencil. Faxon's Gunner profile combines the durability of the Gov't profile with the weight savings and maneuverability of the Pencil profile. The Gunner profile brings the balance of the rifle back towards the shooter's body, limiting fatigue, and allowing for shooting, training, or hunting all day long. Faxon Firearms barrels are the pinnacle of value. Manufactured in-house in Cincinnati, Ohio, Faxon barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy. Quality is imbued into our barrels from the beginning of the manufacturing process.. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel goes through a battery of tests at each operation until finished and final inspected. All barrels are individually checked for headspace with precision PTG gauges.image

Important Product Note: Faxon Match Series 338 ARC AR15 Barrels: Faxon Firearms strives to deliver high-quality products designed for optimal performance. Please note that some customers may need to adjust their upper receiver feed ramps to ensure proper function, particularly when using Hornady Sub-X ammunition. For best feeding reliability, Faxon recommends pairing this barrel with Duramag magazines designed for 400 Legend. Always ensure compatibility with your specific firearm setup and consult a qualified gunsmith if needed. Faxon Firearms is not liable for damage or performance issues resulting from improper installation or use.
