Information on the Leupold Mark 4 Scope

Leupold Index Matched Lens System

• All Mark 4 tactical scopes are integrated with the Leupold Index Matched Lens System, a process utilizing different coating materials for each lens (depending on lens placement, function and specific light refraction). This provides the Mark 4 scopes with their legendary clear visuals.

Windage and Elevation Adjustments

• Mark 4 scopes are equipped with crosshair adjusting dials that are easily accessible and adjustable by hand (most conventional scopes require a screwdriver, although a coin will work, to adjust the crosshairs). The scopes feature ¼ minute of angle (MOA) adjustments that can be measured by audible clicks. MOA is the unit of measure, based on an inch, commonly used with rifle scopes.

Parallax Adjustment

• Parallax error is the illusion of target movement caused by a change in the shooter's line of sight through the scope. Most tactical scopes can manually compensate for parallax with an adjustment to the far end of the scope. Mark 4 scopes have conveniently placed the parallax adjustment dial on the left side of the scope (adjacent to the windage and elevation dials); allowing the shooter to quickly compensate for parallax at different ranges.

Crosshair Magnification

• The crosshairs of Mark 4 scopes magnify in conjunction with adjustments to the scope's power, giving shooters a great advantage with estimating range. Range can be estimated by counting the number of tick marks that the target takes up on the crosshairs. The Mark 4 makes this easy by keeping the size of the crosshairs relative to the size of the target.

Mark 4 Durability

• Leupold produced the Mark 4 to meet and exceed military standards. The Mark 4 is designed to perform exceptionally well regardless of the conditions. Mark 4 scopes are completely waterproof and shock resistant.
