Look, my crown

来吧，让我们来看看我的王冠

Last month I bought a Chinese manufacturer's sights, I bought it again this month, I plan to install it in my crown.

I don't understand what the left and right parts do.

To the left is a vertical angle indicating match dial and to the right is discovery's idea of a range-finder.
