Faxon's Match Series of barrels takes our renowned performance and value up a notch.
Manufactured in-house from gun-barrel-quality bar-stock, the Match Series starts with 416-R in 5R rifling. 5R is a hybrid rifling, with lands opposite grooves and reduced sharp angles that reduces jacket deformation increasing velocity and easy cleaning. After rigorous testing, the barrels are Nitride treated inside and out, locking in the bore, improving barrel life, and keeping the elements at bay.

The extension is coated in a Nickel Teflon coating that maintains incredible dry lubricity, corrosion resistance, and with the coating, tightens up fit between the extension and receiver - again improving upon accuracy. Combined, the Match Series of barrels are ready for when duty calls or the buzzer beeps with unrivaled performance value.

    Love this barrel

    Posted by Chris on May 10th 2023

    After doing a lot of research, I found this company. This was the first of two barrels that I have purchased from Faxon. After all these years, I finally built my very first AR10. I wanted to build a rifle that was very accurate, and in this platform for quick follow up shots. I am shooting right at one MOA (random ammo) with this barrel and I am extremely happy! I'm currently working up my own load data for this rifle to ring out every bit of accuracy that I can. The fit and finish were fantastic. And while I love a great heavy barrel for precision work, I ordered a match series 16 inch .223 Wylde barrel in the gunner profile for a friend building her first carbine. The accuracy of that barrel is outstanding as well. While I have tried many other barrels for different firearms I have built over the years, I will now stick with Faxon for any future builds.

    What an outstanding barrel fit and finish is fantastic and price is just right with proper hand loads this barrel sheets three-quarter inch groups all day long out of my custom built Gas gun.
