Faxon Firearms Barrels have quality embedded in their DNA from the very beginning. Manufactured in Faxon's Greater Cincinnati facility, each barrel begins its life as raw, bar stock. Machined from 4150 CMV or 416-R Stainless Steel, all Faxon barrels are fully stress relieved, air-gauge tested, and 11-degree target crowned to ensure superior accuracy. Each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All Faxon barrels are individually checked for headspace by precision custom hardened gauges. All Faxon Barrels are backed by the Faxon Lifetime Guarantee.
