Mueller's Tactical Rifle Scope is designed to allow for simple calculation for bullet trajectory with its true mil dot reticle. The Mil-Dot reticle features multiple aiming points to compensate for bullet drop or windage compensation with the dots covering only 1/4" of the target at 100 yards. Lenses are fully multi-coated camera quality crystal which provide a bright image that has lots of contrast. Finger adjustable turrets allow for easy windage and elevation adjustments while the fast focus eyepiece provides quick reticle clarity adjustments. This scope is terrific for long range varmint hunting. Lifetime factory warranty.
