|Sniper Rifle, or Sniper’s Rifle?

This is a picture of a Sniper’s Rifle.

Is there even such a thing as a sniper rifle? Or is it a sniper’s rifle? Whenever you see the title of a rifle it never says: “Remington T96 Bolt Action Sniper Rifle”. So, there is really no such thing as a sniper rifle. A sniper is the person who shoots the rifle. So that would make it the sniper’s rifle, meaning: a rifle belonging to a sniper.  Please Comment.
