Due to the rifle's decent rate of fire, any target that survives the first shot can be killed quickly with a second shot before alerting any nearby non-player-characters. With the added bonus of sneak attack criticals, most targets are easily eliminated with a single shot.

The sniper rifle is a semi-automatic rifle, designed primarily as a long-range weapon, it deals reasonable damage, has a scope with 3.5x magnification and very little weapons spread.
