eli5 How are guns accurate if their sights are so high?

Question

Take the ak for exemple, the front sight is like 4 centimeters above the barrel, how is that accurate? Do you just have to compensate for that? Also aplies to scopes, some of the sight quite high on the gun

Edit: i already know they make arcs because of gravity and the angle of the barrel

Answer 1

It’s a known offset and then you are zeroing the optic to the point of impact at a known distance. Depending on the scope and ammo you can very precisely determine the bullet drop compensation needed. The trijicon acog for instance has versions for specific calibers and the hashes are marked for specific distances so you can very easily shoot at different distances without having to re-zero the optic.
