Leupold Mark 4 Long Range/Tactical riflescopes are arguably some of the most dependable, highest performing riflescopes you'll find anywhere. Their accuracy is proven in the field. Their rugged and absolute waterproof integrity is unquestionable. They are everything a long-range competitive shooter, target shooter, or hunter could ask for. Leupold's Mark 4 Extended Range/Tactical M1 and M5 Front Focal riflescopes are designed to let you take advantage of the reach and power of today's long-range rifles. The M5 scopes' mil based adjustments complement the mil based reticles to make long range shot placement quicker and easier. Like all Leupold Mark 4 Optics, the ER/T deliver superior clarity and a generous range of windage and elevation adjustment for the accuracy and precision you demand at extreme distances.

Xtended Twilight Lens System
Now your hunt can reach further into the twilight than ever before possible, with Leupold's exclusive new Xtended Twilight Lens System. 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 most scope manufacturers 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. When Leupold combined that with superior computer-generated optical design, lead-free lenses of unsurpassed clarity and quality, and 100 years of manufacturing excellence, 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.

DiamondCoat 2
Exterior lens surfaces are treated with DiamondCoat 2, an ion-assist lens coating, for higher light transmission and the greatest level of abrasion resistance Leupold has 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 - technology pioneered by Leupold - Select models feature Leupold's 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 Leupold's proven nitrogen technology already does. Leupold pioneered riflescope waterproofing, and now with Argon/Krypton Leupold is exceeding the standards they set themselves.

Generous Eyebox
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 picture 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.
