The Faxon Firearms Match Series .308 Win Barrel (Faxon part number 10B810R20NTMHL5RNP3) is a 20-inch AR-10-platform barrel manufactured in-house from gun-barrel-quality bar stock, starting with 416-R stainless steel and Faxon’s 5R hybrid rifling for improved accuracy and easier cleaning versus conventional rifling. After machining, the barrel is nitride treated inside and out to lock in the bore, extend service life, and resist corrosion, and the extension carries a Nickel Teflon coating that keeps dry lubricity high while tightening the fit between barrel extension and receiver. It is built to fit AR-10-pattern rifles specifically.
