TacFire AR Barrel Features The TacFire AR Barrel is machined from steel and chambered in 5.56x45mm NATO giving AR pistol builders a direct replacement option sized specifically for pistol-length platforms. Its 10.5 inch length strikes a balance between a compact maneuverable profile and the reliable cycling that 5.56 pistol builds depend on. A 1:8 twist rate stabilizes a wide range of bullet weights from lighter varmint loads up through heavier projectiles used for longer range work. The black nitride finish on the barrel s exterior resists corrosion and holds up well to repeated range sessions and field use. Because this barrel ships with no sights installed builders have a clean canvas to mount their choice of iron sights a red dot or a magnified optic without removing factory components first. Replacing a worn or damaged barrel with this TacFire unit restores accuracy and reliability to an existing AR pistol build without the cost of a brand new upper. The steel construction and nitride finish combine to deliver a barrel that is both tough and low-maintenance over years of use. For AR pistol owners looking for a dependable properly sized replacement barrel this 10.5 inch TacFire option fits the bill.
