La Longue Carabine

The  is a unique weapon in Fallout: New Vegas.

Characteristics
It has a scope mounted on the rifle. This rifle also reloads significantly faster than a regular cowboy repeater, and does not load through the loading gate (it lacks one) but through the front of the magazine tube, somewhat similar to Lincoln's repeater. La Longue Carabine cannot be modified using cowboy repeater mods. It already has one mod attached, the extended feeder magazine, although judging by the appearance of the rifle the magazine tube on La Longue Carabine is smaller than a Cowboy Repeater with an extended magazine.

It is a unique variant of the cowboy repeater. It is carried by Corporal Sterling in Camp McCarran.

Locations
Can be found in Camp McCarran near New vegas, it is carried by an old Ranger by the name of Corporal Sterling. He is part of the quest I Don't Hurt Anymore and killing him for the rifle will forfeit the quest.

After killing Driver Nephi and returning to Major Dhatri as part of the quest Three-Card Bounty, the 1st recon unit will move to Camp Forlorn Hope. You can find them all together next to the Jailhouse in the northwestern part of the camp.

Behind the scenes
"La Longue Carabine" is a French phrase meaning "The Long Rifle"; it is a reference to the James Fenimore Cooper novel "The Last of the Mohicans," in which the main character, Hawkeye, is nicknamed La Longue Carabine by the Delaware tribe for his famed marksmanship.

Bugs

 * Though perhaps not limited to the La Longue Carabine, there seems to be a bug associated with this weapon that will sometime cause the player to be unable to switch ammo types, even when a particular ammo type has been exhausted. This is resolvable by dropping, or storing the weapon on a companion, and then requipping it. Though it may still not be possible to switch ammo types while equipped.
