Frequently Asked Questions

MOA stands for "Minute of Angle" and is a unit of measurement used to describe angles in shooting and weapon mounting. One MOA corresponds to an angle of 1/60 of a degree, which at a distance of 100 meters is approximately 2.91 centimeters. When we talk about MOA cant on a Picatinny rail, such as 20 MOA, it means that the rail is angled so that it cants with a rise of 20 MOA from the rear to the front. This cant helps adjust the scope in a more downward direction relative to the rifle's barrel.

The purpose of an MOA cant is primarily to allow for greater upward adjustment in the scope, which is especially important for long-range shooting. When shooting at very long distances, the scope often needs to be adjusted far upwards to compensate for bullet drop. If the rail is completely flat, you risk running out of upward adjustment in the scope before reaching the necessary distances. A 20 MOA rail thus cants the scope forward and downward, which effectively moves the zero adjustment downward and provides extra leeway to adjust the sight upwards for long shots.

It is important to choose an MOA angle that suits your needs. For general hunting and shooting at moderate distances, a flat rail without cant is often sufficient. But if you plan to shoot at distances of 300 meters or more, a rail with a 20 MOA cant can be an advantage, as it provides a better opportunity to fully utilize the scope's adjustment range. When mounting, ensure that the scope can be mounted correctly on the canted rail and that the rail fits your rifle. Overall, the MOA cant is an important technical detail that improves the precision and usability of your optical sight for long-range shooting.

The difference between 0 MOA and 20 MOA refers to the angle a Picatinny rail or mount has relative to the rifle's barrel, and it significantly impacts the scope's adjustment capabilities. MOA stands for Minute of Angle, which is a unit of angular measurement where 1 MOA equals approximately 2.9 cm at a distance of 100 meters. A 0 MOA mount is completely straight and parallel to the rifle's barrel, meaning the scope is aligned with the barrel without any tilt. A 20 MOA mount, on the other hand, is angled downwards with a tilt of 20 MOA, which means the scope points slightly downwards relative to the barrel.

The purpose of a 20 MOA mount is to provide additional upward adjustment in the scope, especially at long distances. When shooting at very long ranges, you often need to aim the scope higher to compensate for the bullet's drop. A 0 MOA mount can mean that you quickly run out of upward adjustment because the scope is already in a neutral position. With a 20 MOA mount, you practically get more upward clicks because the extra tilt means the line of sight starts a little lower relative to the barrel, allowing you to compensate for bullet drop over longer distances.

So when do you use which? If you are shooting at short to medium distances, for example under 300 meters, and do not need extreme upward adjustment, a 0 MOA mount is often sufficient and simpler to work with. If, on the other hand, you are a hunter or sport shooter who often shoots at long distances over 400-500 meters, or if you use a scope with a limited adjustment range, a 20 MOA mount can be a great advantage. It allows you to utilize the full adjustment range of your scope and thereby improve accuracy on long shots.

It is important to choose the mount that suits your needs and equipment, as an incorrect choice can limit your ability to adjust the scope correctly. In practice, you can also find mounts with other angles such as 10 MOA or 15 MOA, but 0 and 20 MOA are the most common. If in doubt, it can be a good idea to consider what distances you usually shoot at and what scope you are using, so you get the best combination for your hunting or shooting situation.

MOA, which stands for Minute of Angle, is a unit of measurement used to specify precision adjustments on rifle scopes. One MOA is approximately 2.91 centimeters at a distance of 100 meters, meaning that when you turn the adjustment turrets on your scope by 1 MOA, the reticle moves approximately 2.91 centimeters on the target at 100 meters. MOA inclination refers to how much the rifle scope can be adjusted in height (elevation) and sideways (windage) in MOA units. The maximum adjustment range on a scope indicates how many MOA the scope can collectively move from the lowest to the highest setting.

The relationship between MOA inclination and maximum adjustment range is therefore direct. If a scope has a high MOA inclination, for example 1 MOA per click, and can be adjusted 60 MOA up and 60 MOA down, it means that the total elevation adjustment range is 120 MOA. The same applies to windage adjustment. This range determines how much you can compensate for distance, wind, or other factors affecting the bullet's point of impact. A large maximum adjustment range is particularly important in long-range shooting, where the bullet can drop many centimeters over long distances, and where precise fine-tuning of the sight is necessary.

It is also important to note that MOA inclination per click determines how finely you can adjust your sight. A scope with 0.25 MOA per click provides more precise control than one with 1 MOA per click, because you can adjust in smaller increments. However, the overall maximum adjustment range depends on how many clicks the scope can be turned in both directions. Therefore, when choosing a scope for specific purposes such as hunting or sport shooting, one must consider both the total range of adjustment available and the fineness of these adjustments.

In short, MOA inclination and maximum adjustment range are related in that the inclination indicates the degree of movement per click, while the maximum adjustment range indicates the total movement you can achieve on the scope in MOA, which together determine both precision and applicability at different shooting distances.

Return to zero, often abbreviated as RTZ, is a function or feature primarily found in adjustable scope mounts and some types of rifle sights. The meaning of RTZ is that after you have made an adjustment to your sight or scope, for example, in elevation or windage, and subsequently reset the adjustment back to the starting point, the sight will return precisely to its original zero position. This means that your sight or scope is not only adjusted in one direction, but you can confidently return to the original calibrated position without losing your initial sight setting.

This is particularly important in hunting and sport shooting, where temporary adjustments often need to be made to adapt to different distances or shooting situations. Without the RTZ function, it can be difficult or impossible to return precisely to the original setting, which can lead to missed shots or the need for repeated calibrations. With RTZ, you can quickly and accurately adjust the sight, for example, to compensate for wind drift or distance, and then return to the original setting when changing targets or situations.

Technically, RTZ is achieved through mechanical stops or click systems in the mount, ensuring precise zeroing. Many modern mounts and rifle scopes offer RTZ as a standard feature, as it increases precision and makes it easier to work with adjustments under various conditions. For hunting, it also provides a great advantage, as you can quickly adapt to changing conditions without the risk of losing your baseline adjustment. Therefore, RTZ is an important feature for both hunters and sport shooters who desire reliability, precision, and flexibility in their equipment.
