Christine's COS silencer rifle

Christine's COS silencer rifle is a unique weapon in the Fallout: New Vegas add-on Old World Blues.

Background
Christine Royce of the Brotherhood of Steel splinter cell, the Circle of Steel, left her rifle near Little Yangtze as she hunted for the estranged Father Elijah, similar to her recon armor inside the Y-17 medical facility. Before she could apprehend Elijah, he sent the ghoul prisoners of Little Yangtze after her, detonating their collars as they got close as a distraction. He made his escape soon after to Elijah's Watch.

Characteristics
The rifle is visually identical to the generic sniper rifle common to the Mojave Wasteland, but comes with a suppressor pre-attached to the muzzle. Like the other sniper rifles, the scope of this weapon has a 3.5x magnification. It also has higher damage than the regular sniper rifle or any other .308 caliber weapon in the game, outclassing even This Machine. However, it fires slightly slower than its normal counterpart, but due to its increased damage per shot still maintains a slightly higher damage per second value.

In addition it has a slightly higher AP cost in VATS, weights 2.5 lbs less, has a higher critical damage, a higher critical multiplier, and is slightly more durable than the sniper rifle.

Like most unique weapons, it cannot be modified. Due to its low weapon health of 85, only 5 points higher than a regular sniper rifle, it degrades almost as quickly as the standard variant.

Variants

 * Sniper rifle, the common variant.
 * Gobi Campaign scout rifle, a unique and more powerful variant of the sniper rifle.

Location
The rifle is found leaning against the wall in a corner right next to an ammunition box on the top floor of the crumbling building outside the north wall of Little Yangtze. It is hard to see as it blends in with the wall.
