Telescopic sight

A telescopic sight, commonly called a scope, is a device used to give additional accuracy using a point of aim for weapons such as firearms, airguns and crossbows. Other sighting systems are iron sights, red dot sights, and laser sights.

The UNSC uses scopes on a wide variety of its weapons, ranging from its sniper rifle variants to its battle rifles and even its rocket launchers. the Covenant also use scopes (eg; the Carbine and Beam Rifle), though the mechanics of their equipment are unknown.

There are a wide variety of scopes, each differing in type, function, and purpose. For example; the standard scope of an S2 AM Sniper Rifle is capable of 5x or 10x magnification for long range combat, and are electronically operated. The Scopes on the BR55 and BR55 HB-SR, however, are only capable of 2x magnification, intended only for short- to medium-range accuracy, using focussing lenses for magnification. The S2 AM Scope also includes a night vision function in some models for night combat.
