16" GUNNER, 5.56 NATO, Mid-Length, 4150 QPQ

  • Product Description

    Just what is the GUNNER profile?

    The GUNNER (all caps, as it is that awesome) is the pinnacle of performance, weight, balance, and value. Designed by our competition shooting staff for those who value performance and versatility, the GUNNER profile is a blend of two of the best performing profiles of all time, Gov't and Pencil. 

    Proving that every once and awhile, the Government can do something right, the GUNNER's profile from the extension to the gas block mimics that delicious taper. From there, common sense takes over and the GUNNER moves to a .625" gas block journal and our famed pencil profile out front.

    Removing the weight from the front of the barrel ensures maximum versatility and keeps material to the rear to maximize heat resistance and mitigate whip.

    Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle-to-grave, these 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 start. 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 by precision custom hardened gauges. 

    Faxon manufactures all our barrels in Cincinnati, Ohio under our ISO:9001 and AS:9100  quality certifications.

    1. I'm starting to repeat myslef

      This Barrel is performed as good or better than I expected. I have quite a few barrels from Faxon firearms and I have come to trust in their accuracy, the craftsmanship, reliability, as well as their customer service.

      Feed ramps and extension are very clean and nicely done. Fit to my various upper receivers have been very consistent and borderline tight (this is a great thing).

      Great profile offers weight savings without jeopardizing function and longevity. With the right ammunition combination I am experiencing sub MOA groups.

      Highly recommend this barrel and many others offered by Faxon Firearms.

    2. 16" Gunner Barrel is Perfect

      I have used the 16: Faxon Gunner barrel in a few applications and find superb accuracy, combined with great fit, finish, contour look and attractive over all weight package for the complete rifle.

      Great barrel and reasonably priced... I recommend this barrel for your next 16" AR platform build!

    4. Buy this barrel if you want the best!

      After having one of my customers ask me to build them a lightweight AR I started to research what would be the best barrel I could find that would fit his requirements. After some time we settled on Faxon’s 16” Gunner barrel. This is one of the best barrels out there.
      The Gunner barrel is top shelf, very accurate, the contour and weight is perfect and you can’t beat the price.
      We have use this barrel in over 20 builds and will never look back.
