Faxon's Match Series of barrels takes our renowned performance and value up a notch.

Manufactured 100% 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.

    6.5 grendel barrel

    Posted by george laudun on Mar 2nd 2024

    This was my first Faxon purchase along with a Faxon BCG for my build and I’m thoroughly pleased. The accuracy is outstanding and quality craftsmen ship are second to none. I’ll be buying more Faxon products for my next build.

    Has served me well.

    This barrel has been great since building the rifle. It has shot every bullet I've tried in it sub MOA with typical load work up. I have since purchased a 16" 223 Wylde heavy fluted barrel that I suspect will shoot just as well.

    Absolutely love this barrel. Looks great and shoots straight. Only have been able to go out 200 yards but I’m hitting quarters! Very pleased!

    6.5 Grendel, 20", heavy fluted barrel

    Posted by rYd on Mar 3rd 2018

    Quality product, fit and finish are all top notch. Have not had a chance to shoot it yet but I expect it will be very accurate. Only complaint I have is with USPS. Priority Mail took over two weeks to be delivered.

    6.5 grendel barrel 20in. Fluted heavy

    Posted by Patrick Seiler on Feb 6th 2018

    I had an Alexander Arms 6.5 grendel years back. Faxon quality is above original. Was using Hornady match black. 2 in groupings at 100 yards. 200 2.5. That was with wind compensation. Best barrel for the money if you want to do a 6.5 grendel.

    I build custom AR platform guns & the overall craftsmanship of this barrel is excellent. Fit & finish is second to none. And it ‘shoots’; after break in it shot a 5 shot group/100 yds that we covered with a dime. Enough said.
