This is a special rifle, as it comes with an integral silencer attachment, with a further option to add a muzzle break.
Their special equipment is a side-mounted optic to make it easier to aim at very short ranges. With proper special ammo however, these can, with a powerful optic, still punch with the heavyweights as long as you take your time.
This class is suited largely towards shorter range engagements, such as eliminating patrols and shorter range sniping contracts. They specialize in being adaptable, and with their special equipment being specialize barrels, you can tune them to more long range fights or for fights that are a little more personal. Medium Rifles are a Jack-of-all-trades kind of class. Their Special Equipment is the Bipod, you don’t need to deploy it, it offers a passive buff to the weapon’s stability, and when used while prone, makes for an excellent long range platform. This class excels at long range contracts, and are at times necessary to secure reliable one hit target kills, which will make your life much easier.
Each of these three classes have unique equipment available to them, differing slightly between each rifle within that class. There are 3 classes of rifles (as of two weeks post release), these being Lightweight Rifles, Medium, and Heavy Rifles.
