Every component of your Leupold Mark 4 LR/T 4.5-14X50MM SF M1 Rifle Scope with Tactical Milling Reticle is working together to help you make every shot count, whether you’re at the range, hunting, or in a tactical environment.
Xtended Twilight Lens System
With the exclusive new Xtended Twilight Lens System, your hunt can reach further into the twilight than ever before possible. It goes a step further than even the Index Matched Lens System, using Leupold's index matched glass with wavelength specific lens coatings designed to optimize the transmission of low-light wavelengths. When others quote percentage of light transmission, they usually mean at 550 nm, the green wavelength where the human eye is most sensitive. The challenge is that in twilight conditions, green light disappears and blue/violet light takes over. Your eye is already handicapped when it comes to seeing the blue/violet spectrum, and if your scope is cutting too much of it out, soon you won’t be seeing anything. The Xtended Twilight Lens System places extra emphasis on matching coatings to glass indices to achieve the best possible transmission of the blue/violet spectrum, without sacrificing the color balanced light transmission across the visual spectrum of the Index Matched Lens System. Combine that with superior computer-generated optical design, lead-free lenses of unsurpassed clarity and quality, and 100 years of manufacturing excellence and you have a scope that gives you the details of low-light scenes in greater definition and luminance than any other scope in the world.
Exterior lens surfaces are treated with DiamondCoat 2, an ion-assist lens coating, for higher light transmission and the greatest level of abrasion resistance we've ever offered. DiamondCoat already exceeds military standards for hardness and durability. DiamondCoat 2 offers unsurpassed durability and will prove its worth in the wildest places on earth. DiamondCoat 2 has the additional advantage of assisting in light transmission, for greater brightness, clarity and contrast.
2nd Generation Argon/Krypton Waterproofing
While Leupold still waterproofs other optics with bone-dry nitrogen, select models feature our exclusive, proprietary Argon/Krypton gas blend. Its advantages are two fold: it nearly eliminates the effects of thermal shock, and the Argon/Krypton molecules are significantly larger than nitrogen molecules, reducing the diffusion of gases sealed inside your scope even more than our proven nitrogen technology already does. Leupold pioneered riflescope waterproofing, and now with Argon/Krypton they’re exceeding their own standards.
The generous eyebox makes it faster and easier to get your eye behind the riflescope and achieve a full, clear sight picture. Setting up for longer shots you'll appreciate the flexibility it affords, and in close up big game or dangerous game situations the quick target acquisition will be the difference maker. At high power, the longer eye relief and more generous eyebox gives you incredible head position latitude and an improved sight pictue that fills the eyepiece completely - putting you in better position to make the shot of a lifetime.
Blackened Lens Edges
Blackened lens edges reduce unwanted glare and diffusion through the lens edges to provide better resolution, improved contrast and superior optical performance.
All Leupold optics offer performance that makes them equally at home in hunting or tactical environments with outstanding accuracy, legendary ruggedness, and absolute waterproof integrity. Leupold Mark 4 Long Range/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 who shoot competitively at ranges of 600 yards or more rely on the accuracy and durability of these scopes.
