Description
In New Vegas there's a specific location that provides the player with a unique weapon. However the weapon you receive depends on if you have selected the Wild Wasteland trait at the character creation section at the beginning of the game.

You can either get,
The YCS/186 Unique Gauss Rifle Without Wild Wasteland.
or
The Alien Blaster With Wild Wasteland.

This is inconvenient for those who like to collect unique weapons as you can only get one, or the other, not both.

This mod aims to remedy this by making the YCS/186 spawn inside the BOS Safehouse when the player has the Wild Wasteland trait.

You could use a mod such as the Get Both Alien Blaster and YCS186 mod to use the Sink Auto Doc in the Old World Blues DLC to reset your traits in order to get both weapons. However there are mods that exist that change Wild Wasteland from being a Trait and make it it's own integrated option like
Better Character Creation and Wild Wasteland Integrated. This makes using the Sink Auto Doc ineffective as Wild Wasteland is no longer a trait.

I decided on the BOS safehouse because i didn't want to just hand the weapon to the player on top of the Alien Blaster like other mods of the same type do. I wanted to integrate this weapon in a more immersive way and also in a location that requires some work to get access to.

I also added a note next to the weapon to explain how it found it's way there. 

Now something to bare in mind. This is my very first "actual" mod that i've ever made besides my Western Ambience Overhaul. So my knowledge with the GECK is limited. I did manage to make the weapon only spawn with Wild Wasteland enabled. If you do not have it enabled, then the mod will not spawn the weapon. I may make an update that spawns the Alien Blaster without wild wasteland but i need to figure out a fitting place to spawn it.

Requirements
The Wild Wasteland Trait, obviously. No additional mods or DLC required.
