Welcome to Optics Trade debates. In each episode, we talk about a different topic and try to answer the most common questions we receive about it. Today we are going to talk about the adjustment per click or click value.
This topic is for beginners, someone who is entering the world of shooting, hunting, and all other shooting sports.
The click value tells you how much the impact of the bullet moves on the target when you turn the knob for one click.
For more information watch our video about Click value below
Click values in different scopes
1/2 MOA click value
Scopes are produced with different click values. If we start with wide-angle riflescopes, they commonly have a click value of ½ MOA, which means approximately 15mm per 100m. In the USA they usually use different methods of measurement implementing the imperial measurement system and they say that ½ of MOA will move ½ of an inch in 100 yards.
1/4 MOA click value
The most common click value on the American market is ¼ of MOA. That means that the point of impact moves for 7mm at 100m on the target or ¼ inch at 100 yards. This click value is the most common with producers from the USA, Japan, China, Philipines, and Korea.
0.1 MIL click value
Europeans usually use 1cm on 100m. This is used on hunting scopes, BDC turrets, and modern hunting scopes. This is used on about 99% of all tactical scopes. They are marked with 0.1 MRAD or 0.1 MIL.
1/8 MOA click value
With target scopes, for precision shooting the click values are really small because all the adjustments are fine. They are most common at 0.125 or 1/8 of an MOA. That means that the point of impact shifts for 3.5mm at 100 m.
Some European producers of target scopes also produce 2.5 mm click which are the finest on the market. Schmidt&Bender has a scope like this, the 12–50x56 can be ordered with the click value of 2.5mm per 100m.
- Generally, the most used click value in target scopes and precision shooting is 1/8 of MOA, 3.5mm per 100m.
- The most common value for wide-angle scopes is 1cm per 100m or ½ MOA per 100 m.
- Hunting scopes from the USA, Japan, China, and Korea most commonly use ¼ MOA, 7 mm of shift on 100 m.
- With tactical scopes, the value is 0.8 MRAD or MIL and it is the gold standard that all tactical scopes use.
- The gold standard for target scopes is 1/8 of MOA which means 3.5 mm of adjustment per click.

Explanation of Adjustment per click on our website:
Adjustment per click is, how many centimeters/millimeters will move on the target at 100m when you make one click on the turrets for elevation or a point of impact windage on the rifle scope. Clicks are usually specified in MRAD (1mrad is 10cm / 100m) or MOA (1MOA is 2.9 m / 100m). Some manufacturers designate MRADs with the acronym MIL.
Practically all newer rifle scopes have the possibility to adjust reticle left or right (windage) and up or down (elevation). This process is known as zeroing. The upper turret on the riflescope is for elevation adjustment of the reticle and the side turret on the riflescope is for windage adjustment of the reticle. Hunting rifle scopes have the mechanism of both turrets protected with caps that protect the turrets from water, damage or any other outside impacts. Turrets are in other words rotatable buttons which you can spin left or right.
Every single movement made with the turret produces a 'click' sound. Usually, 1 click on European rifle scopes moves hit on a target for 1 cm at 100 m range (0.1 MRAD / MIL). On American, Japanese, and Chinese scopes 1 click moves the hit on the target for ¼ MOA (minute of angle) which is 7 mm at 100 m range. On Benchrest rifle scopes, where corrections have to be very small, the clicks are either 1/8 MOA (3,5mm / 100m) or 0,05 MRAD (5mm / 100m).
At last, soemnoe who comes to the heart of it all
Yes! someone has at last explained if written in a few words that we all understand, all that is needed to know to put theory into practice. Great stuff guys in one area Britain still rules the waves and long may we do so. Thank you.
