Telescopic sight

Background
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.

Function
The UNSC uses scopes on a wide variety of its weapons, ranging from its sniper rifle variants, to its battle rifles, and even its handguns. 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 focusing lenses for magnification. The S2 AM Scope also includes a night vision function in some models for night combat.

The M41 Rocket Launcher and the Covenant Fuel Rod Cannon both have 2x scopes, as well, to better pinpoint targets and to extend their effective range.

Past Models
The ACOG scopes, or Advanced Combat Optical Gunsights, that were used in the pre-2000s, are not confirmed if they are still in service during the Halo Universe.
