An adjustable objective lens allows for parallax-free shooting, without moving the scope's point of impact. Our Micro-Trac 4 point adjustment system is simply the best in the industry. T-Series lenses are fully multi-coated to reduce glare, increase image brightness and give you unparalleled clarity. T-Series scopes come standard with an extra pair of oversized benchrest adjustment knobs, a sunshade and screw-in metal lens caps.
