A sniper rifle is a rifle that is used for precise engagement of targets at extended ranges. They typically are able to hold 1 minute of angle (MOA) or less at range, and are chambered in either an intermediate rifle cartridge (if intended for law enforcement usage) or a full-size rifle cartridge. Sniper rifles, due to their intended usage, almost always have a telescopic sight mounted. Some military sniper rifles also have back-up iron sights in case of telescopic sight breakage. Sniper rifles can either be a semi-automatic rifle, or more often, a bolt-action rifle.
Sniper rifles generally use camouflage while some are simply painted with olive drab.
