A while back I seen these Marshmallow guns posted by Mr. BadWrench and decided to pick up a couple. It took me forever to get around to modding them, but finally… here are my results.
Start with this:
Open it up to see the internals.
First thing to do is glue this little hose down. It is weak and expands, so I super glued it down and coated it in plumber’s goop. Note: plumber’s goop does not stick to the hose plastic, so in the future I will be replacing this hose.
Next I took the front piece off and boiled it in hot water until the glue gave way, this allowed me to not have to cut the pump handle. Do not cut the pump handle as it goes all the way into the pump housing only leaving the little piece that is glued sticking out.
For my pump handle I used a piece of 3/4 PETG pipe and epoxy puttied it to the stock pump handle to extend it, then I added a foam rod butt cap (fishing rod building material) to the end to make it comfortable to pump.
For the barrels I cut off 2 inch sections of OMC PETG and then used a 5/8” brass tube as the attaching sleeve. The original barrels have a nice funnel pinch point on them that holds the darts great and gives it a popping noise when shot.
The turret uses magnets to align the rotation, but when pulling the trigger quickly these have a tendency to skip or not align up correctly. So I took some Foam sticker sheets and cut out two small pieces to create a friction point to slow down the barrel. This has cause that issue to disappear.
Next, put it all back together and go crazy with your 15 shot semi auto rear-loading pistol.
Ranges: 25-35 feet with 3/0 mod darts. I am sure I would get better range with single bb darts, but I don’t have any to test at the moment.
