Vendortron

Vendortron is a Protectron manning the Gun Runners kiosk outside of Freeside $$

Background
Vendortron sells weapons and ammo for the Gun Runners. According to the Vendortron, the kiosk was built around it in order to deter theft and assault. As such, the Vendortron and its stock are invulnerable.

Weapons
The store has five inventory tiers (the inventory is random and may not include all weapons listed below): Finishing the Honest Hearts add-on will also make the .45 Auto pistol, .45 Auto submachine gun, war club, yao guai gauntlet, tomahawk, and fire bomb available for purchase. Similarly, after completing Lonesome Road, rockets and nails will be sold. Sometimes, however, rockets and nails can be purchased before even starting Lonesome Road.
 * Tier 1 (player level 1): silenced .22 pistol, varmint rifle, 9mm pistol, .357 Magnum revolver, single shotgun.
 * Tier 2 (player level 1): 10mm pistol, 9mm SMG, cowboy repeater, service rifle, caravan shotgun.
 * Tier 3 (player level 6): .44 Magnum revolver, lever-action shotgun, silenced .22 SMG, 10mm SMG, hunting rifle, sawed-off shotgun.
 * Tier 4 (player level 11): trail carbine, hunting revolver, assault carbine, sniper rifle, hunting shotgun, 12.7mm pistol
 * Tier 5 (player level 16): riot shotgun, 12.7mm submachine gun, marksman carbine, minigun, light machine gun, brush gun, anti-materiel rifle.

Weapon mods

 * Vendortron can carry most weapon mods available in the game, even while purchasing with a level 1 character.
 * It will always have all Honest Hearts and Lonesome Road mods once the player finishes the add-ons.

Ammunition

 * If Vendortron sells a gun, it will also have a chance of stocking the appropriate ammunition. If the ammunition appears for purchase, it will be in a large quantity (usually in a stack of 100+ of non-rare ammunition types).

Misc

 * Vendortron sells all of the components needed to make weapon repair kits: duct tape, scrap electronics, scrap metal, wonderglue, and wrenches. It also sells various ammunition crafting components, such as primers, gunpowder, and empty casings, all in bulk containers.

Aid

 * Vendortron never stocks aid items, apart from the occasional weapon repair kit.

Appearances
Vendortron appears only in Fallout: New Vegas.

Behind the scenes
On a terminal inside the Gun Runners factory, it is suggested that the Vendortron's name be changed from Vendortron to an actual name "like Bob. We're not calling it Bob" which is a reference to the 2000 post-apocalyptic science fiction film Titan A.E.
