XShot Piston Pump DIY Bullpup Kit

Take any barrel shroud for your beloved MPP and make it into your own cursed bullpup! It requires two M3x10mm screws, but outside of the wiring, it re-uses the spring on the pull mag release (since you won't be using it anymore,) you can reuse or get a different microswitch, however, make sure it doesn't have a lever arm on it, and uses 18ga wire or smaller. You should probably use smaller. I used 18ga and it was pretty fiddly to get it routed internally and into the grip piece. How you get your wiring to the grip piece is entirely up to you. I'm not gonna tell you where to drill holes into your shell. That's your life decision to make. 

The greep piece is optional. Use it or not, it'll function just fine, more or less emotional devastation though. 

The lock pins can be tweaked for fit and finish.

So long as your shroud has picatinny, you can slap this kit on there. If you have other blasters that use the smaller micro switches for either revving or firing, you can slap this kit onto those blasters and MAKE EVEN MORE CRINGE BULLPUPS. 

Go forth. Create. Have Fun. Wince at your awful new ergonomics.
