Questions & Answers
Do the barrel come with Barrel Nut and Shims? Manufacturer Answer

No, barrels do not ship with barrel nuts. These most often are shipped with the handguard you choose.

by Faxon Firearms, Manufacturer, April 30, 2026
Based on this UPC/Code for the 12.5” barrel, it’s the “combat” series not “duty”. I checked in Faxon’s website. Can someone confirm? Thank you! Manufacturer Answer

Yes, the 12.5" barrel listed here is part of our Combat line of barrels.

Product Info for Faxon Firearms Duty 5.56 NATO Rifle Barrel

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 in Nitride and final inspected. All barrels are individually checked for headspace with precision PTG gauges.image
