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.

When you enter the museum, go into the Lincoln exhibit hall, on the left as you enter. Once you clear out the mutants, poke around until you find a door for the museum offices. The rifle is in a display case, next to a desk. It is on the same floor as the photo of Lincoln Memorial, if you are doing the Head of State quest.

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.
