MAR1071 1-4.5 x 24mm was specifically designed for the Service Rifle match shooter who shoots at various distances up to 600 yards. New rules went into effect in October 2015 that allow scopes with magnification up to 4.5x. This scope also makes a great optic for SWAT work as well as for a sporting rifle. Oversized tactical turrets allow for easy windage and elevation adjustments. The high-quality ED lenses provide exceptional image resolution that make March the best in its class, according to the company.
