Product Info for Faxon Firearms 20in, Heavy Fluted, 6.5 Grendel, Rifle-Length

The Faxon Firearms 20in Rifle-Length 416-R Stainless Steel QPQ Barrel is a premium Match Series barrel that utilizes 5R rifling. The 5R rifling in these AR15 Barrels by Faxon Firearms uses opposite groves and reduced sharp angles that decrease jacket formation while increasing velocity and allowing for easy cleaning. For increased durability and reliable performance, the Faxon Firearms 20 in Heavy Fluted Barrel is Nitride treated inside and out which will deter harsh elements and preserve the longevity of the barrel. The extension on this barrel has a Nickel Teflon coating that provides further corrosion resistance and maintains a dry lubricity while also tightening the fit between the extension and the receiver which helps improve accuracy. Swap in the Faxon Firearms 6.5 Grendel Barrel to get the most out of your weapon and consistently deliver impeccable results in the field.image
