Nerf LMG (Light Machine Gun) (unfinished)

*NOTE*
This is a project that I am currently unable to finish, as I simply don't have enough time or money. I wanted to post this here in case anyone likes it or is interested in it.

Here's a brief rundown of what this beast of a nerf gun is all about:
-Nearly 1.1 meters long
-Belt fed loading system (inspired by the Nerf Vulcan)
-Chambers both Mega darts and normal sized Nerf darts
-Unsure on rate of fire as of right now
-Fully automatic
-Powered by a 7Ah 12V sealed lead acid battery
