A scope is a tactical rail or accessory rail accessory that is advertised to help users improve their accuracy.
Despite the function of a scope being to improve one's accuracy, scopes are often not accurate by themselves; this is usually due to their positioning on the blaster.
Unlike their real world counterparts, most scopes do not feature magnification; with the exception of the Day/Night Zoom Scope, none of the scopes have any sort of magnifying abilities. Many features small plastic inserts with crosshairs printed onto them that act as if they would function as lenses, although these do not serve any purpose other than for aesthetics. A few accessories labelled as "scopes" seem to draw more design inspiration from modern reflex sights rather than telescopic sights, such as the Ninja Commando Blaster scope or the Heatseeking Scope.
