A high precision sniper rifle. It is great for long range attack and usually kills in one shot to the head. it fires 7.62mm SLAP (Sabted Light Armor Percing) rounds and features an adjustible power scope. It appears to be based in a visually modified PSG-1 style rifle.
The SR-125 Sniper Rifle is a long-ranged weapon that can be encountered rarely in Area 51. It is wielded by Black Ops forces on occasion, but is usually found in proximity to dead human military forces.
With a well-aimed shot, it is a one-hit kill on both mutants and Black Ops forces, and can be invaluable when in the caverns. The Sniper Rifle does not carry a high amount of ammunition (6 Cartridges, or 24 shots) for it's maximum capacity, but can be useful regardless of that, if used well.
The SR-125 Wraith is an incredibly efficient weapon, but can be limited in effectiveness by the close quarters nature of many spaces in Area 51. As such, there are only a few spots in which it is useful.
It can also be used at close range if you need to dispatch an enemy quickly and easily, as it should be fairly easy to get a headshot on a Black Ops soldier, and not too tough to land one on a mutant, either.
Enemies wielding the SR-125 are generally easy to locate, and thus do not tend to pose much of a threat, but if one cannot be found quickly it is recommended to find cover and look for the source of the bullets being fired from a safe distance.
