Sniper Rifle (Fallout 3)

The .308 DKS-501 is a Small Guns weapon in Fallout 3.

This sniper rifle is an older model of the famed DKS-501. Still chambered for .308 ammunition, it's also extremely fragile and requires regular repair and maintenance to keep it in working condition.

Characteristics
The sniper rifle is much more effective when fired outside V.A.T.S. mode, as V.A.T.S. does not take into account accuracy bonuses of the weapon's scope.

Outside V.A.T.S., with 100 Small Guns, the weapon can shoot as far as the game will draw NPCs (Playing at high resolutions will greatly improve NPC visibility). However, the point of impact is higher than where the center of the scope is aimed. After the fire button is pressed, the scope aim will very rapidly jump up and shift slightly to the right almost at the same time the shot is actually fired. This is to simulate how the amount of force required to pull the trigger impacts the user's aim as it is pulled. See the images below to determine how to compensate for this.

The sniper rifle has very noticeable sway to it when manually aimed. The sway can be reduced with either a higher skill level in small guns, or when in sneak mode. At 100 points in Small Guns, the scope has no sway at all, though even at 100 points in Small Guns, having either of your arms crippled will result in severe sway while using the scope.

The first two images below, taken from the southwest guard platform at Fort Bannister, will be a 1-shot kill. The color of the first shot has been inverted to improve clarity. The third picture shows how much aim compensation is needed for a head shot at very long ranges.

It can be noted that the point of impact is always at the same length up along the vertical crosshair line above the center of the scope and slightly to the right.

A fully-repaired sniper rifle can fire 83 .308 rounds, or about 17 magazines, before breaking.

Variants

 * Victory rifle - While identical in strength to the Sniper Rifle, the Victory Rifle has an additional 200 item HP, and knocks down targets with critical hits. However, it pays for this ability with a reduced critical chance of 3.
 * Reservist's rifle - Also identical to the Sniper Rifle in strength, the Reservist's Rifle uses less AP to fire, but only holds 3 rounds in a magazine. It also fires slightly faster, and has slightly less recoil when using the scope.

Locations

 * In the Bethesda Ruins, there is a raider with a sniper rifle west of the Offices West building very close to the spawn point. Every 72 in-game hours the raiders respawn. There is also a raider on the catwalk between the Offices East and Offices West buildings who carries a sniper rifle and has some ammo nearby. He doesn't respawn.
 * On the bridge/overpass exactly north of Vault 101, South of Big Town, on the fourth or fifth raider from the beginning of the bridge. This raider too respawns every 72 hours.
 * The Hollowed-Out Rock south of Megaton is easy to reach very early in the game.
 * Behind Arlington Library, in Talon Company Outpost; respawns with merc.
 * If you accept the quest You Gotta Shoot 'Em in the Head from Mister Crowley in the Underworld he will supply you with one.
 * Arkansas, found in the town of Minefield.
 * Allistair Tenpenny of Tenpenny Tower. You can kill him while he's on the balcony of the top floor of his building or once he goes inside (you gain karma for killing him but you are heavily advised to kill him outside, and if you kill the guard and the other people upstairs, no one downstairs will know you murdered them).
 * Knight Captain Dusk of the Brotherhood of Steel.
 * The second floor of a ruined house near Hubris Comics along with some ammo and a skill book. (When facing the park in front of Hubris, it is the last building to the right.)
 * In the elevated shack to the south of Warrington Trainyard, along with some .308 ammo.
 * In Mama Dolce's you can find one or two on Chinese Remnant soldiers on the balconies overlooking the shipping yard.
 * Wheaton Armory has two sniper rifles in the missile silo behind a Very Hard Door.
 * In the Point Lookout add-on almost every smuggler group has at least one smuggler carrying a sniper rifle.
 * In the Point Lookout add-on after exiting the Underground Lab there is a smuggler carrying a sniper rifle and frag grenades on a small island south of where the Lone Wanderer climbs the ladder out of the lab. This smuggler respawns every 73 in-game hours.
 * Sold by the following merchants:
 * Gustavo or Michael Masters, occasionally.
 * Flak 'N Shrapnel's, occasionally.
 * Moira, rarely.
 * Knight Captain Durga, occasionally.
 * Sydney in Underworld after Stealing Independence, occasionally.
 * Lucky Harith after fully investing, occasionally.
 * Pronto after completing the Economics of Violence, occasionally.
 * Seagrave Holmes, rarely.
