Choosing a tactical optical sights depends on a number of factors including your needs, weapon type, preferences and budget. Consider the type of weapon you have. Some scopes are designed for carbines, others for rifles, and there are models that can be mounted on different types of weapons. Consider different types of scopes, such as variable magnification scopes (variable magnification scopes allow the user to adjust the magnification for different situations) and fixed magnification scopes. Also consider that some rifle scopes are illuminated for low light conditions.

I have already found where you can buy such high-quality equipment, but it is also very important to have a good overview https://www.atneu.uk/thermal-monoculars.
