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.

    Opens up w/ heat

    Posted by Sheldon Lee on Feb 16th 2022

    I like to accuracy test my semi-auto barrels after warming them up a little as well as starting with a cold gun. While this barrel performs well for me when cold (1.2 MOA 5 round groups, acceptable for my purposes), I get poor performance when warm (slowly fire 1 20 round magazine, reload with 5 rounds of match ammunition and group), opening up to about 2.4 MOA in a lateral string pattern - still good from a military standpoint but a little disappointing. I wonder if this isn't partly due to the stresses introduced by machining out the flutes and if a barrel with less external work done might be better. This barrel strongly prefers heavier ammo, with best performance so far coming from 175 gr. Nosler and SIG loads.

    Faxon 20" match 308. Good shooting barrel.

    Posted by Andrew on Jan 4th 2020

    When it showed up there was a bad ding on the shoulder side were the barrel nut makes contact and applies torque to upper reciver. I had to file that away. Fitment to the upper was super tight and I loved that. So as for aesthetics would have been 5 out of 5 easy if not for the dent/ding. Why not ship your match barrels in something better then a bag? That's seriously my only issue as this barrel shoots really well and the bore is seriously nice. FAXON PLEASE UPDATE YOUR PACKAGKING!

    Extremely impressed

    Posted by Christopher on Jul 10th 2018

    I purchased this barrel based on several weeks of research and more research, trying to find the best quality I could afford for my build. The packaging and shipping were excellent. The nitride finish is very robust. After following the break-in process, this barrel will certainly out-perform me. From Hornady match ammo to bargain bulk ammo this barrel takes it all and still delivers superb accuracy and very easy cleaning. I will definitely recommend this barrel and Faxon Firearms to anyone. High quality without the ultra-elite price.

    Another great barrel

    Posted by Kyle Hayden on Nov 27th 2017

    I purchased this barrel several months ago and have been able to put approx 300 rds of match ammo through it.After following Faxon's break in procedure I have been able to consistently shoot 1/2 - 5/8 inch groups at 100 yards and ring 8" and 10" plates at 600 yards with no problem. This is the second barrel I have purchased from Faxon and could'nt be any happier. The other barrel is a 20" 308 pencil on a light weight hunter build. This barrel is sitting on a JD Machine matched upper & lower, Faxon match bolt carrier, SLR adjustable gas block, SLR ultra light handguard, Gamma VG6 break, CNC 3.5 trigger, Magpul PRS Gen3 stock, Vortex Razor HD 5x20. Atlas bipod. My son in law is an active duty Marine Corps Sount Sniper and instructor at Sniper School. He loves this rigle and says it will out shoot their Knights M110 SASS all day long. I'm shooting Hornady 168 BTHP Match and Federal 168 BTHP Sierra Match King.
