When choosing the optics of a weapon, it must be clear what is planned to be done with it. How quickly and accurately do you need to aim? Red dot sights and cylindrical (higher magnification) are the two main types of optical sights.

First, ask yourself the questions – what are you placing the sight on?

Pistol or rifle?
Do you want to shoot short or long range targets?
What is the target size?
Will the actual gun get the optics it deserves?
