The Leupold Index Matched Lens System delivers superior resolution from edge to edge of the visual field - even at 14x - along with peak image brightness and optimal contrast. Leupold engineers specify different coating materials for each lens surface in the riflescope, based on the lens' index of refraction, placement and function, layering each coating to eliminate reflections and maximize light transmission.
Every feature was put in place for one purpose: to help you get the maximum advantage from your rifle, whether you're hunting or in competition. Outstanding accuracy, legendary ruggedness, and absolute waterproof integrity. All Leupold optics offer performance that makes them equally at home in hunting or tactical environments.
Leupold Mark-4 Extended Range/Leupold tactical riflescopes are excellent choices for both long-range hunting and varminting. Likewise long-range competitive shooters and members of the Fifty Caliber Shooters Association - men and women who shoot competitively at ranges of 600 yards or more - rely on the accuracy and durability of these scopes.
The Mil Dot reticle provides accuracy of range estimation for hunters and target shooters. With practice, the Mil Dot system is simple to use. Dots are spaced in one mil (milliradian) increments on the crosshair. Using the mil formula, the shooter can create a table based on the known size of the object targeted. Just look through the Leupold scope, bracket the object between dots, and refer to the table for an estimated distance to the target.
With the reticle in the front focal plane of the ER/T, the reticle magnifies with the image so you can estimate range using Leupold's Mil Dot reticle at any magnification setting.
Other features for the Mark-4 ER/T M5 FFP Rifle Scope include: 30mm maintube; tall adjustment dials; 1Mil Elevation, and 1Mil Windage adjustments; 60-MOA of both windage and elevation adjustment. Side focus parallax adjustment for fast, easy parallax focusing from 50 yards to infinity, from any shooting position. Flip-open lens covers are standard issue with each Mark-4 ER/T riflescope.
The Mark-4 ER/T 4.5-14x50 M5 Rifle Scope is backed by Leupold's Tactical Optical Products Warranty.
