The TAC II contains two carbon fiber tubes, offering a more compact system tailored for weapons with shorter barrels that are still in use as precision platforms. The TAC II is made with the same design/components as the TAC III. It earned the “must have accessory” tag by US Military personnel operating as Designated Marksman. The TAC II allows the shooter to move the resting point of their weapon approximately 44 inches away from the toe of the rifle*. When fully extended it measures 20 inches. When retracted it measures under 13 inches. The O.D. of its base tube is 40mm (1.575”). The TAC III weighs under 1.5 pounds.
