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 Nickel Teflon which 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.

    6mm ARC 20inch heavy fluted barrel

    Posted by Adam on Oct 15th 2023

    This is the second upper I've built for an AR and my first Faxon product, and the fit and finish on this barrel is very nice. I don't have a ton of rounds through this barrel yet but so far I am very happy with the results out to 300yards with factory ammo. Will be a fun target gun and will be great for white tail this year. This won't be my last Faxon purchase.

    Absolutely GREAT! Probably the most accurate AR15 that I have ever built. And that's with factory ammo.

    This barrel is extremely accurate, I have no problem grouping 0.5 moa at 100 yards. And its much more light weight than the ballistic advantage barrel. I highly recommend it

    The barrel does the work for accuracy. High end parts for support--3.5# aftermarket trigger, matched upper and lower, Aero bolt etc, etc... Shot Hornady 103 gr ELD-X; stacked one upon another fresh from the start; am looking only to get better with further break-in. Get you some venison--out to about 300 yds with full confidence, still has 1100+ ft-lbs energy. Light weight build even with Eliminator lll ballistic calculator scope--would hike anywhere with the combo.
