Mil-dot Reticle Makes Calculation of Range Easier

One of the most outstanding features of the Leupold Mark 4LR/T scope comes with a none-illuminated mil-dot reticle, which comes with a number of advantages such as excellent versatility and easy range estimations.  This feature enables skilled shooters to calculate the distance between them and their targets very easily, thereby significantly enhancing their shooting experience. The calculation is done using dots along the crosshairs of the scope.

Blackened Lens Edges Reduce Unwanted Glare

Unlike most scopes whose edges produce unwanted glare that might distort the quality of your image, The Leupold Mark 4 8.5-25×50 mm MR/T M1 has blackened edges that greatly reduce reflective glare, enable high resolution, and ensure optimal viewing experience.

Spacious Eyebox and Eye-relief Enhance Flexibility and Prevent Scope Bites

The scope’s spacious eye box prevents ambient light from interfering with light from the scope, and, thus, preventing the annoying situation of your view being interrupted.  Also, the adequate eye relief of 3.7 to 5.3 inches that the scope proudly features not only keeps you comfortable when looking through the scope but also protects your eyes against heavy recoils.

 2nd Generation Argon/Krypton Filling Prevents Damage From Water

The makers of the Mark 4 8.5-25×50 MR/T M1 have taken things a step further by filling the scope with special argon gas, whose sole aim is to prevent  water from forming fog inside the scope’s lens and impairing your vision. Indeed, the argon gas filling is a massive improvement on the company’s signature nitrogen gas filling (bone-dry nitrogen technology). But really, what makes the Argon/Krypton more superior than the bone-dry nitrogen technology? The simple answer is because the molecules of argon gas are significantly larger than that of nitrogen, and as a result of that they are more effective in mitigating the diffusion of the gasses contained inside the scope, thereby making waterproofing and fogproofing more effective. It is worth noting that this impressive feature also gives the scope the ability to resist the effects of thermal shock.

DiamondCoat 2 Lens Coating Ensures Quality Viewing Experience

The scope’s lens is coated with the renowned ion-assist lens coating known as DiamondCoat 2™. This coating provides an amazing viewing experience by allowing a lot of light into the scope and improving contrast and clarity. The coating also makes the lens resistant to different types of shocks and abrasions that it may be subjected to while you are in the field.

Xtended Twilight Lens System makes it Possible to Hunt at Twilight

Certain scopes do not come pre-designed for viewing under twilight conditions, where there’s less green light and more blue/violet, which the eyes are naturally unable to see very well. But the Leupold Mark 4LR/T isn’t like that! The manufacturers of this scope engineered it with the Xtended Twilight Lens System™ which makes use of index matched glass and proprietary lens coatings to open up blue/violet light during low-light conditions to provide you with images that are brighter and sharper. With this feature, you enjoy more flexibility in the timing of your hunting/tactical operations!  Not too many scopes allow you to see as effectively as the Mark 4 8.5-25×50 MR/T M1 allows you to in twilight conditions or low-light conditions. This simply means that you can use the scope anytime you like – whether day or night.

Multicoat 4 Lens Coat Provides Amazing Viewing Experience

Multicoat 4 is yet another coating that the scope’s lens has been treated with in order to maximize the amount of light that flows through the scope. In addition to massively enhancing light transmission, this coating also prevents unnecessary reflections of the sky and other light in your surroundings, ultimately providing a unique viewing experience.

8.5-25x Magnification Enables Detailed Viewing of Target and Assures Safety

With the scope’s 8.5-25x magnification, you can now view several minute details of your target than ever before. Furthermore, your safety is assured because such detailed viewing can be done over long distances, up to 1500 yards.
