A riflescope is an optical device mounted on a rifle to enhance aiming accuracy. It magnifies distant targets, allowing shooters to see them more clearly. Typically, a riflescope consists of a series of lenses, a reticle (crosshair), and adjustment knobs for windage and elevation. Riflescopes come in various magnification levels and sizes, catering to different shooting needs, such as hunting or target shooting. They are designed to withstand harsh conditions and often feature waterproof and fog-proof construction. Properly using a riflescope can significantly improve shooting precision and overall performance.
