This Machine

 is a weapon in Fallout: New Vegas.

Characteristics
is chambered in .308 and holds eight rounds at a time. It is in excellent condition when found. The gun is modeled after an M1 Garand, and even the infamous 'ping' of the empty clip ejection is heard when reloading.

Aside from the rare copies of the same weapon, there is no other weapon that can repair this one. Since there is no "regular" version of this gun, the only way to repair this weapon is with the Weapon repair kit or using the Jury Rigging perk with other weapons in its class (Rifles, such as the Hunting Rifle). You can also see Major Knight in the Mojave Outpost, or Raul in his shack, and pay the caps to fix it.

Locations
There are several ways to obtain this weapon.

is given to you either by Contreras if you don't turn him in at the end of the unmarked quest Dealing with Contreras, or by Carrie Boyd if you do.

Alternatively, you can get the quest to discover if Contreras is stealing weapons, then you can simply hack Contreras's computer 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.

It can also be found on one of the Praetorians in Caesar's Tent in the Fort.

Appearances
only appears in Fallout: New Vegas.

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 "Well This Machine Kills Commies", written on the left side of the weapon. (personally, This Machine Kills Legionaries)

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%.
