Dynamag pump action mod

Make the boomco dynamag into a pump action blaster!

Assemby:
Glue the two barrel parts together, sand the seam so the grip slides freely over it, glue or screw the barrel to your dynamag (flush with the top), drill a hole through the back of the original priming slide, feed a long bolt through it with a flat bar on either side, connect the bar ends to a bolt through the new priming grip and done. The original priming slide is a bit narrower than the widest part of the blaster so you'll need to fill that space with some rings or an extra nut.
If it doesn't slide freely loosen the nuts and bolts a bit or sand the T-rail on the barrel a bit.
