Size Chart

Medium profile for maximum heat resistance during spirited firing. 4150 QPQ coated inside and out for amazing corrosion resistance and durability. 

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.

    If you're looking for a top-notch, excellent, barrel, look no further. Go ahead and buy this. Barrel came absolutely perfect. Inside and out. Shoots sub MOA. I'll never buy another barrel from another company again.

    Excellent barrel, although a bit pricey. QPQ finish is outstanding, and very snug to the gas block (although I had to debur the gas port a bit).

    1" shot groups at 100 yards, even after barrel heats up.

    I have used ESS in the past, but as they have scaled back production on what I need, I will use Faxon instead.

    Would easily purchase again.

    Very nicely milled barrel. The m4 profile is sharp looking and the qpq finshe is beautifully done. I cant beleive how inexpensive this barrel is for what you get. It's high end without the price. The barrel went into my upper without issue. Had a chance to rattle off a few round on my new build and everything function properly. Did not have a chance to site it in and see what it can do for accuracy though. Would recomend to a friend. Don't hesitate to by this barrel you won't be disappointed.

  • Amazing barrel.

    This is my first Faxon barrel and I was very impressed with not only the look and quality but how well it's performed. My rounds are hitting the targets every time. I appreciate how Faxon gives a military discount. To all my fellow service members out there make sure you take advantage of that. I would definitely recommend this Brand/product to anyone looking to build/replace a weapon system.

  • Great looking product.

    This is my first try with Faxon Firearms and am well pleased with it so far. I only have about 200 rounds through it so far but am loading up another 400 for it now. So for the accuracy at 100 yards is as good as I can shoot without a scope, including the break in... The fit and finish is just as it looked in the pictures and it went right in. I would likely buy another !
