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.

    Perfect for my lightweight AR15 complete upper assembly. With other lightweight components, this new build upper weights 3.14lbs including an Aimpoint ML3 and Larue QR mount.

  • Lightweight and well made

    If you are looking at this barrel, you probably know what it is and why you want to buy it. It is 100% worth the money, especially at this price. This barrel was purchased for my wife's rifle, and now I want one for my rifle. The barrel is surprising lightweight, especially coming from the ubiquitous government profile. The finish is excellent, and her rifle points fast and easy. So far, only one range session with 90 rounds of Tula, 150 rounds of Federal XM193, and 525 rounds of 22lr put down the barrel. No problems, and I don't expect there to be any.

    Aerospace Arms processed my order same day, and shipped the next. I had the barrel in my hand two days later. I could not be happier with their service and I would recommend buying from them.

  • VERY LIGHT!

    I have not finished building so I can't speak to the accuracy of this barrel, but the fit, finish, packaging, and delivery time is incredible with this. Delivery was fast (2 days from when I ordered it). It came in a sturdy tube with plenty of padding. It fits my upper incredibly tightly and holds straight even without the barrel nut on yet. The Nitride is a nice deep black completely devoid of blemish or whirl. I'm looking forward to finishing this build and testing the performance of this barrel.
