Lincoln's Repeater (Fallout 3)

Lincoln's Repeater is a .44 rifle, with a 15-round magazine, found in Fallout 3. It is located, in perfect condition, inside of a display case in the top floor of the Museum of American History offices.

Upon entering the Museum of American History, make your way to the Lower Levels, which is located on the left as you enter the big room with the giant prehistoric animals. Once in there, walk up the left staircase and go into the room filled with empty (or destroyed) displays and enter the offices door on the left side of the room in the back. Make your way through the offices until you come to a large, open room with a turret on the ceiling. Walk up the staircase that is against a wall in the front of the room. Upon reaching the top, you should see a giant hole in the wall. Go in there, and in furthermost cubicle on the left you should find the rifle waiting inside a display case on a desk.

It fires .44 magnum rounds, but is repaired with Hunting Rifle parts. The rifle is devastating when used with the Commando and Sniper perks, which boost rifle accuracy in V.A.T.S.

You can also sell this to Leroy Walker who occupies Lincoln Memorial and will destroy it to erase Lincoln's legacy. Otherwise, you can also sell it to Hannibal Hamlin after completing the Head of State quest, who will enshrine it.
