Physical Properties of Leica Magnus 1.8-12×50 i

There is no denying the amazing physical properties of the Leica Magnus 1.8-12×50 i. To begin with, the finish on this riflescope is exceptional. The magnification ring turns smoothly and effortlessly. Additionally, the diopter adjustment ring can be easily adjusted to your preference. Lastly, the illumination knob is also very user-friendly and easy to use.

The length of the riflescope is approximately 340 millimeters, making it very compact and elegant. It weighs around 700 grams.

The parallax on Magnus 1.8-12×50 i scope is not adjustable. It’s fixed on 100 meters or 109 yards.

Because of its 12x magnification, the scope is best used for hunting at close to medium range. It’s also perfect for hunting in various lighting conditions, from low light to full bright daylight. This riflescope has a magnification range of 1.8-12 and a 6x zoom factor with an objective lens diameter of 50 millimeters.

Mounting of Magnus i scope

Magnus 1.8-12×50 i riflescope has a tube diameter of 30 millimeters, but the buyer also has the option to buy this product with a Zeiss ZM/VM rail. If the user wants to add more robustness to their rifle scope, we advise ordering the riflescope with a rail, which will ultimately make the riflescope more sturdy.

Leica Magnus 1.8-12×50 i Reticle

The reticle on the Magnus 1.8-12×50 i riflescope is in the second focal plane and designed for hunting. This scope has an L4A reticle that is illuminated. In the past, this scope was also available with an L-Ballistic reticle, but it has been discontinued.

Illumination System

The illumination system on the Magnus i series of riflescopes is worth noting. It’s designed with a large illumination knob that can easily be adjusted, even while wearing gloves or with just bare hands.

This highly intelligent illumination system is usable in both daytime and low light conditions. It has a setting for day and night use, with 60 steps of adjustable brightness levels. This allows you to set your illumination down to the finest detail.

To adjust the illumination, press down on the illumination knob. The minus and plus symbols on either side of the knob indicate whether you want to increase or decrease brightness. Simply press down on the appropriate side of the knob to make your selection.

The Magnus 1.8-12×50 scope has a position sensor that auto- shuts off illumination when placed on its side or vertically, saving the battery in the process.

Like we said before, you can use the scope even in the brightest daytime conditions. Another improvement from the first series to the second one is that the dot size is more defined and covers a smaller area than on the first generation of Magnus scopes. Also, the intensity of illumination is just as strong. This might be the most ergonomic rifle scope available for purchase.

How to replace the battery?

Replacing, removing, or installing the battery is a breeze. Just remove the illumination knob and place a CR 2032 battery inside before screwing it back on.

This riflescope has an improved battery holder mechanism that is easy to use. Simply turn the knob, insert the battery, and close it up. The battery will stay put and not move around, so you don’t have to worry about it coming loose.

So, this is an improvement from the first series of this rifle scopes. With the earlier version, the battery holder didn’t have this notch which caused problems – for example, if you were hunting in low light and needed to replace your batteries when you opened up the knob they would just fly away. This problem was elegantly solved.

Turrets and clicks

When we get to the turrets, this 1.8-12×50 model comes with capped hunting turrets. This scope is also available with a BDC turret, which is without a doubt one of the finest turrets on the market. We’ve already put it to the test, and we think it’s great.

Clicks are adjusted in one centimeter on 100 meters or in 0.1 MIL increments. Turrets have no turn indicator, which is not necessary on a hunting rifle scope. 

The elevation per turn is 10 milliradians. The turrets are resetable in a very unique and unusual way: by pressing them down. This is something new. You press the turret down and it can be effortlessly reset. This is an easy and clever solution by Leica.

Turrets have no locking function. They don’t require it since, these are hunting turrets, not tactical or target turrets. Turrets are just about right audible. The clicks are extremely crisp and well-defined. Turrets are incredibly easy to use, and there is no need to divert your attention from what you’re doing. Overall, turrets are excellent.
