The Mueller Multi-Shot is a highly versatile scope. The multi-use circle dot reticle works great for turkey hunting with a shotgun as the circle covers 14" at 40 yards, and the illuminated dot is ideal for big game hunting with a rifle as the dot covers 1" at 100 yards. Lenses are fully multi-coated camera quality crystal which provides exceptional brightness and contrast, and the low profile finger adjustable turrets allow for quick adjustments in the field. Lifetime factory warranty.
