Manufacturing Excellence

Each barrel is manufactured in-house and subjected to rigorous quality control. The barrel is fully stress relieved to ensure dimensional stability and accuracy. Air-gauge testing verifies bore concentricity, while precision custom hardened gauges individually check headspace on every barrel.

Faxon's engineering carefully tapers the barrel profile to shed weight while maintaining structural integrity and thermal stability. The result is a barrel that performs like a full-profile design while weighing significantly less—ideal for shooters who value both accuracy and handling.

The 1:10 twist provides the versatility to stabilize the full spectrum of .308 Winchester ammunition, from lighter target loads to heavy magnum offerings.
