Leupold Mark 4 ER/T 4.5-14x50mm (30mm) M1 Front Focal TMR Review


They are generally known as The Leupold and Stevens Incorporative. It is an American company that produces telescopic sights, red-dot sights, binoculars, and riflescopes. Headquartered in Beaverton at Oregon in the United States. The company, founded in 1907, continues to operate even today after five generations of a healthy business.

The company was set up by people who were German by descent and immigrated then to the US. The founders were Markus Freidrich Leupold and his brother-in-law Adam Voelpel, who started this initiated by producing surveying equipment. After a while, the company got contacted by a person named John Cyprian Stevens to provide a water level recording device that he had patented. After a glaring success of the product, he became a partner of the firm in 1914

Apart from the water level recorder, the company also came up with other important innovations such as the Telemark water recorder which got its patent in 1939. The spectacular thing about the device was that it could transmit water level information over telephones, allowing remote sensing as a technology to flourish.

However, since 1942, the name of the company took its present form. Equipment for surveying and riflescopes got manufactured with the Leupold branding. And the monitoring equipment started to conduct its business under the Stevens parentage. By the end of the 70s, Leupold riflescopes started generating almost twice the amount of revenue generated by Stevens equipment.

Today the scopes manufactured by the company are used in diverse places. The US army, the NAVY seals, and the secret service are loyalists of their products. The NAVY and the Marine Corps also take a keen interest in using their product. The Israeli troops have been a fan of the Mark 4 and Mark 6 Leupold scopes. They are also known for creating binoculars for game hunting for civilians.

How to use a riflescope?

Making use of a riflescope is an integral part of learning to hunt. Traditionally, iron sights got used with rifles. But it is essential to remember, that the rifles fire bullets at an extreme velocity. So iron sights couldnt track the shots fired, thereby making it less accurate. Here is where riflescopes come in handy, where accuracy gets maximized along with speed. Here are different steps to use riflescopes:

  • Make sure that your position is at the opposite end of your spotted target- the optimum distance between the target and the shooter should be 150 yards for testing out the quality of the scope. Any target located beyond that number is going to hamper the accuracy, and you might eventually miss your mark. For people who are starting in this field, a hundred yards should be the starting point
  • There should be no one in the vicinity of your shooting practice, that is between you and the target- your line of fire should be spotless. The edges of the range of fire should also be kept clear of people, and they shouldnt be allowed to trespass. The only safe place to be at is probably behind the person shooting
  • Choose your shooting stance wisely from a wide array of positions- the different area available to marksmen is the standing position, the kneeling position, and Prone. The standing position entails holding the gun. You can, however, use the scope when you are kneeling or in the prone. The prone position is appealing to most shooters. It implies, lying down prostrate on your belly while aiming. Calibrate the scope only when you are set nicely in your position
  • Take a trial run of your shot by looking through the scope first before shooting- when you have your first glance through your scope, your eyes will hit a set of cross-hairs. The crosshair is nothing but the coincidence of a vertical and horizontal line that will help you focus on the target entirely. The point where the two lines meet is where one should aim with the rifle. With perfect calibration of the scope, the impact of the bullet will be precisely at the midpoint of the crosshairs
  • For a precise shot, the crosshairs should get placed at the center of the target- take a test shot always to get a proper understanding of the impact of the shot fired. If the bullet hits the goal too high or too low, then the elevation adjustment should be used for better calibration. However, the bullet hitting left, or right of the target should make you realize that the windage should be tweaked or not. The windage adjustment is usually on the right of the rifle.
  • All initial modifications should get tested. At the first test run, the calibration should be done correctly, before you zero in on your target. Make sure that every time you shift your mark, there is a proper calibration following the distance. Anytime you see your shot miss by a couple of inches go ahead and calibrate the scope. Recalibration to the subtlest of degrees can give you a precision hit.

On what basis should you choose a reticle?

In modern terminology, we refer to reticle as crosshairs. Game hunting crosshairs get mostly made out of wires; however, to enhance accuracy, most marksmen have opted for crosshairs which get etched on glass. Reticles offer you nothing but an excellent aiming point which is difficult to comprehend with naked vision. Apart from giving you an aiming standard, it helps you to hunt in shallow light conditions. Leupold today have over seventy reticles available; however, with their reticle viewing program, you can have a comprehensive view of them through their website. Here are the most basic kinds of reticles:

  • Original reticle- one vertical and one horizontal line meeting to form the aiming point of the reticle
  • Dot- the most simplistic reticle which is composed of a dot surrounded by a concentric circle
  • German- the sides and the bottom of the reticle are thicker than the center, and they taper towards the center. Sometimes, however, even the top part is thick
  • Duplex Reticle- when all four sides are more packed with a tapering center
  • BDC- for extreme long-range shooting

To fulfill all these expectations, you will probably need a Leupold riflescope. By the grace of Leupold and Stevens, you will find the Leupold Mark 4 ER/T 4.5-14x50mm (30mm) M1 Front Focal TMR, and Mark 6 in the market.

Features of Mark 4

Mil-dot reticle

It is a feature that makes handling of the Leupold Mark 4 ER/T 4.5-14x50mm (30mm) M1 Front Focal TMR this easy is a mil-dot reticle, which is one of the advanced features of this device. A mil-dot reticle is best known for its versatility and its long-range operability. This feature makes sure that the shooter can easily make an approximation of the distance between the target and the shooter. It, in turn, enriches their shooting expertise. The estimate gets done by making use of the dots on the reticle.

Blackened reticle

Most lenses in scopes have edges that produce a lot of glaring effects that create a diluted version of the image. The Leupold has a lens which has got its sides blackened, that efficiently mitigates the glare, further the cause of high-resolution image formation and ensure a better sighting experience.

Enhanced eye relief mechanism and eye box are spacious

The eye box of the Leupold Mark 4 ER/T 4.5-14x50mm (30mm) M1 Front Focal TMR is spacious enough for your eye to see things. However, it is also compact at the same time, to make sure that the ambient lighting doesnt interfere, and distort the image of the target.

Second generation argon/krypton in the insides

The producers of the device went all out by filling the insides of the Leupold Mark 4 ER/T 4.5-14x50mm (30mm) M1 Front Focal TMR by argon gas. Because of its inert nature is not going to catalyze the formation of fog and help it accumulate to paralyze ones vision. It is a significant improvement from the nitrogen-filled scopes of the same branding. The superiority of the argon lies in the fact that its molecules are larger than of nitrogen, which makes it possible for reducing the diffusion of different gases inside the main tube, which in turn makes it an efficient fog proofed and waterproofed machinery. This add-on also enables the machine to stand firm against thermal shock.

Lens coating

Diamond Coat 2 is the official lens coating partner of Leupold Mark 4 ER/T 4.5-14x50mm (30mm) M1 Front Focal TMR and is categorically an ion-assist lens coating. This coating enhances entry of light into the scope, and brings a lot of crispness, and contrast to the pictures. The coating also enables the lens to stand against shocks and falls while you are at the field shooting away to glory.

Twilight lens system

Few scopes have been successful under the twilight sky as the concentration of the deeper shades of color in the lens in place of the greens make it difficult for our eyes to gauge. The scope here is fitted with the extended twilight lens system, that makes use of index glass, and opens up a range of blue/purple light during low ambient lighting. To make sure that the images formed are of an optimum resolution. With this feature, one is expected to have a flexible shooting spree irrespective of time. Not many scopes will enable you to see as nicely as this does during twilight.

Multicoated Lens

It is the second type of coating made for the Leupold Mark 4, which allows entry of more light than usual through the body of the scope. Along with light entry, the coating also prevents redundant reflections of the sky and the ambient objects which provides you with an undisturbed viewing experience.

Up to 25x Magnification

With magnification ranging from 8.5x to 25x, now you can view your target in a different light with much more attention to detail. Detailed imaging can be afforded up to 1500 yards, which implies long-range shooting.
