Sankaku Channel/sniper rifle

In military and law enforcement terminology, a sniper rifle is a rifle used to ensure accurate placement of bullets at longer ranges than small arms. A typical sniper rifle is built for optimal levels of accuracy, fitted with a telescopic sight and chambered for a military centerfire cartridge. The term is often used in the media to describe any type of accurizing firearm fitted with a telescopic sight that is employed against human targets, although "sniping rifle" or "sniper's rifle" is the technically correct fashion to refer to such a rifle.

Not to be confused with the anti-materiel rifle, the sniper rifle's big brother; although they operate in a similar fashion and serve similar purposes.
