A versatile, all-around big-game hunting scope. Features the Circle-X reticle, which frames the crosshair with a circle for precise aiming. A good fit for muzzleloader rifles. Waterproof Construction - O-ring sealed optics stay dry inside, even when totally immersed in water. Fully Multi Coated - Multiple layers of anti-reflective coating on all air-to-glass surfaces deliver bright, high-contrast images. Side Parallax Adjustment - Adjust and align the focal plane of the reticle without removing eyes from the target.
