Faxon Firearms Duty Series Gunner 16in .300 Blackout AR-15 Barrel, Nitride 15A38C16NGQ

Product Description

The Faxon Firearms Duty Series 16" Gunner .300 Blackout (300 BLK) AR-15 barrel is engineered to deliver an ideal balance of strength, weight savings, and handling. Faxons Gunner profile blends the durability of a Government contour near the chamber with Pencil-like agility toward the muzzle, helping keep the rifle balanced and reducing fatigue during long training days, range sessions, or hunts. Built from 4150 CMV steel and finished with a salt bath nitride treatment inside and out, this barrel is designed for long service life, corrosion resistance, and easier cleaning. Each barrel is manufactured in-house in Cincinnati, Ohio, then stress relieved, air-gauge tested, and individually headspace checked for consistent reliability and accuracy.
