A riflescope is an optical device mounted on a rifle to enhance accuracy when aiming at a target. It uses a series of lenses to magnify the view, allowing the shooter to see distant objects more clearly. Most riflescopes also feature reticles, which are crosshairs or other markings that help the shooter align their aim. Riflescopes come in various types and magnifications, catering to different shooting needs, such as hunting or target shooting. They can be adjusted for windage and elevation, enabling users to compensate for environmental factors. Popular brands include Leupold, Vortex, and Nikon.
