This Machine

 is a weapon in Fallout: New Vegas.

Characteristics
is chambered in .308 and holds eight rounds at a time. This Machine is in excellent condition when found.

As this weapon is unique, there is no other weapon that can repair it. The only way to repair this rifle is with weapon repair kits or using the Jury Rigging perk with other weapons in its class. The player can also see Major Knight in the Mojave Outpost or Raul in his shack, paying in caps to repair the weapon. This rifle is effective in mid-to-long range combat. However, long range combat is somewhat difficult due the gun's spread.

Locations

 * is given to the player at the end of the unmarked quest Dealing with Contreras, by Contreras if he isn't turned in, or by Carrie Boyd if he is.
 * Alternatively, you can get the quest to discover if Contreras is stealing weapons, then you can simply hack Contreras's computer (50 Science) on the second floor of the supply shack, read the Weapon Manifest, and then turn him in to Lt. Boyd.
 * This weapon can also be obtained by selecting the option to turn Contreras in after having delivered his medical supplies. Be warned though, as he will attack you if you choose this option. After having killed him, go to the Terminal Building, and tell Lt. Boyd that you have proof Contreras was involved in illegal activities. She will give you the weapon, claiming she had taken it from Contreras, simply because he was annoying.

Behind the Scenes
is a reference to the slogan "This Machine Kills Fascists," which American musician Woody Guthrie had written on his guitar. On the rifle, the slogan is changed to the response "Well This Machine Kills Commies," written on the left side of the weapon.

Bugs

 * One can also obtain the weapon in the following way: on the mission to meet Price, talk to Keller, and use the passphrase. When he replies, choose the option to say that is not the correct password. Attack him afterward (dialog option), and then return to Contreras. The dialog will be bugged and you can choose the option that says you've convinced the ranger to work with him (in death), and he'll give you the gun.
 * In some games, This Machine will never degrade below 80%.
