What do The X's on A Rifle Scope Mean?

The numbers on a rifle scope, such as 8x20, indicate the magnification power and objective lens diameter. The first number (8 in this example) represents the magnification power, meaning the scope magnifies the image 8 times. The second number (20) denotes the diameter of the objective lens in millimeters.

It's important to note that higher magnification isn't always better. Magnification is directly proportional to the scope's length. Higher magnification results in larger scope dimensions and weight, making it less convenient to carry. Additionally, magnifications over 15x can cause eye fatigue. Therefore, choosing the right magnification depends on your specific needs and shooting scenarios.

Lower magnification scopes are generally lighter and easier to carry, making them suitable for close-range or mobile shooting. Higher magnification scopes are better for long-range shooting, providing a more magnified target image, but they come with increased weight and bulk.

Other factors to consider when choosing a scope include objective lens diameter, lens quality, and focus range. A larger objective lens diameter provides a wider field of view but adds weight. Lens quality directly affects image clarity. The focus range determines the scope's sharpness at different distances.

In summary, when selecting a rifle scope, you should consider magnification, objective lens diameter, lens quality, focus range, and other factors based on your specific needs and shooting scenarios to ensure the best shooting experience.
