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.

    Great barrel, fast shipping

  • No compromise

    Posted by Tyler on Mar 29th 2016

    I waited until I had a chance to shoot this barrel before reviewing it. I'll start at the beginning... before I ordered a barrel, folks at Faxon were very responsive to all of my inquiries about different products, and availability timelines nothing worse than asking about a product and getting an answer 3 days later, Faxon answered any question I had within minutes, or hours. Shipping was fast, barrel arrived in very nice, protective packaging, finish was flawless. I instantly told a family member about this barrel and they went and bought a 300 blackout from faxon (have not shot that one yet, but everything said above is the same with that barrel). Installation was very easy, I put this barrel on an aero precision enhanced upper... finished the build and finally got to shoot it. Could not have asked for better performance from this barrel, it's very accurate (more than I am). I was also concerned that maybe the gas port would be too big, or my gun would end up being over gassed, or some sort of issue, since this was my first rifle build, but perfect ejection patterns, not a single stoppage. I have to agree with the many customers of Faxon and say that this has to be one of the best quality barrels for much less money. Zero compromises using a faxon barrel.

  • High quality price is right

    Very high quality. I would like to see a pre-dimple or pin option for the barrels. The Faxon gas blocks use three set screws spaced differently from other manufacturers.

  • excellent barrel, reasonable price

    I have built four AR's around this Faxon barrel after the first build provided everything I was attempting to obtain in a light, easy handling and accurate carbine. Most of my shooting is at steel, rocks, dirt clods and cans of every size and shape.
    The Faxon barrels are beautifully machined and surface prepared with a nitride process resulting in long wear. My first rifle has in excess of 5000 rounds of ammunition with no suggestion of a loss of accuracy. Installed the AR balances well this barrel aiding in quick movement on targets.

  • Fantastic

  • best barrel!

    If Faxon keeps making these barrels the way they are, and same price range then all my builds will bee with this barrel no question. Two thumbs way up!!

  • Very nice barrel

    Posted by Braden on Feb 12th 2016

    This was my first barrel from Faxon. I have heard great things, and I must say that the barrels lived up to my expectations. It arrived in perfect condition and was very nice to look at as well. The finish is glossy, and adds a great look to my build. The threads were precision reamed and the chamber was very accurate. The rifling was also immaculate. The gas block that I ordered with the barrel was a precise fit as well. Overall, great barrel, good shipping times, no complaints here!

  • nice quality for the money

    Posted by Matt on Feb 10th 2016

    I havent gotten to the range to shoot yet so i cant comment on accuracy, but fit and finish on the barrel is superb, the barrel balences well under my geissele mk8 rail, and the geissele gas block i used fit snug, and was easy to dimple the set screws, overall i am pleased with faxon, shipping was fast and i heard good things so i figured for the price why not, and im glad i did!
