So apparently Thingiverse didnt upload all the files I had selected, So I went through and uploaded any missing files.
This is a 3 Barrell Shotgun from the game Borderlands called the Bandit Room Clener
Yes that is how they spelled it.
There are a lot of parts to this prop but the assembly is not difficult.
Video of the assembly can be found here
There was an extra part added after the assembly video was made that is completely optional, and its the display in the back of the scope.
