The 3x Backlit Scope is a sight type attachment introduced to BATTLEGROUNDS in Update 12.The 3x scope represents a compromise between the 2x and 4x scopes. The reticle can be used as a rangefinder for targets between 100 meters out to 400 meters by using the shoulder width of a target and matching it up with the horizontal lines. The reticle brightness can also be adjusted to current lighting conditions.
