The best pellet gun scope consists of one or more lenses or an optical system providing magnification and often serving as the sighting device. One of the most important considerations in choosing a best gun scope is to match the magnifying power and objective lens diameter to the power and type of the rifle being used.
The closer the assailant is, the greater the magnification. The further away the assailant is, the less power.
Objective lenses are either fixed or adjustable, ranging in diameter from 18 to 50 millimeters depending on the power of the scope.
