- Usually ships in 1-2 business days
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.

I spent quite a bit of time researching barrels before making my purchase. This is a lot of barrel for the money. I was very pleased with the quality and overall finish. I really liked the fact that the threads are 1/2x28 since I already have a suppressor mount in that size. The lightweight profile is a big plus also. While I haven't had a chance to shoot it a lot, I can say that function has been 100% and it has been plenty accurate for ringing steel plates with no trouble. I would highly recommend it for anyone building an AR based 9mm pistol or SBR.
