  • The second number, 32 refers to the diameter of the lens on the outer side of the scope, close to the muzzle. These numbers can vary significantly.

It is important to add that these days, most scopes come with variable magnification that can go anywhere between 3.5X up to 20X. This allows you to adjust the magnification according to your needs.
