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.
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.
Three lobotomites will spawn to the north once you take the rifle. However, they are all facing away from you, and can easily be killed from where you are.
If you read Elijah's notes in the watchtower across the Yangtze Camp, he mentions "something glinting, as if someone was watching him" from the building where Christine's rifle is found. He suspects this may have been the courier he met earlier, but then discounts this suspicion as the courier would have been more direct. It can be inferred that this was Christine's scope reflecting sunlight.
It is also one of few unique weapons to share the same model and color as its original counter-part (silencer aside).
