A rifle scope is an optical sighting device mounted on a rifle to magnify the target and improve shooting accuracy. It consists of a tube containing a series of lenses and a reticle, a pattern of fine lines or markings in the eyepiece that helps the shooter aim precisely at the target. The magnification level of a rifle scope can vary, with some offering variable magnification to suit different shooting distances and conditions.

Rifle scopes offer several advantages over other sighting systems, such as iron sights and reflex sights:

Enhanced target visibility: A rifle scope makes it easier for the shooter to see and identify the target at longer distances by magnifying the target.
Improved accuracy: The reticle in the scope helps the shooter maintain consistent sight alignment, contributing to better shot placement.
Adjustable magnification: Many rifle scopes have variable magnification, allowing the shooter to adapt to different shooting distances and conditions.
Customizable settings: Rifle scopes often come with adjustable settings for windage, elevation, and parallax, allowing the shooter to compensate for external factors.
