A rifle scope is an optical device attached to a firearm that helps improve accuracy when aiming at a target. It magnifies the view of the target, allowing the shooter to see details more clearly. Most scopes have crosshairs or reticles that assist in aligning the shot. Rifle scopes come in various magnification levels and sizes, catering to different shooting needs, such as hunting or target shooting. They are typically mounted on the rifle using rings or bases, and many modern scopes are designed to be waterproof and fog-proof for reliable performance in various weather conditions.
