Accuracy International Barrels are available for Accuracy International rifle systems. They are interchangeable with other calibers and the most interesting part is, the interchanging can be carried out in the battlefield in as little as fifteen minutes. The barrel is clamped in a strong, precision machined and professional quality barrel vise that accepts and clamps the barrel securely. When required, the barrel is unfastened from the action and its counterpart is screwed into the action. It is then tightened in place with the help of a torque wrench. The Accuracy International barrels are mostly available with the standard length of 26 inches. They are chambered up with the help of reamers. Custom length barrels, custom cerakote colors and muzzles that can be threaded according to the user’s specs may also be available.
