Frequently Asked Questions: Accuracy & Guarantees

Faxon didn’t get to and continue to build bomb cases, parts for NASA, or deep-sea exploration parts without a commitment to quality.

It’s easy to understand how confident we are in our barrels and products when one sees the manufacturing and inspections that we build into each offering. Individual barrels each go through multiple checks individually well before final inspection. All our products are subject to tight controls of our world-class Quality and Engineering teams.

For example, we air-gauge all our barrels to ensure that each of them has less than .0002” deviation in concentricity (about 10x smaller than the width of a piece of paper) from chamber to muzzle. Anything else is rejected.

What your thoughts on accuracy guarantees?

The accuracy of a weapon system depends on many variables including, but not limtied to:

  • Barrel
  • Receiver to barrel fitment
  • Headspace
  • Ammo
  • Optics
  • Trigger
  • Shooter Ability
  • Muzzle device quality
  • Etc.

While the barrel does make a significant portion of the mechanical accuracy of the weapon system, if even one of the other variables is off, accuracy can be significantly degraded. Since Faxon as the barrel OEM does not control, measure, and account for the other variables, we cannot “guarantee” accuracy. We believe to do so is disingenuous for just the barrel.*

*We do believe one can guarantee accuracy from a full rifle, where it is measured, controlled and tested.

This does not mean that we are not confident in the performance of the barrel. There is a reason Faxon barrels have gone to win 3-Gun, IDPA, USPSA, and other rigorous competitions. Customers repeatedly report fantastic groupings and we fully encourage those interested to explore reviews, testimonials and forums where customers report their real-world results.

To us, those results speak far louder than any “guarantee”.
