This is a really basic mod and could be achieved by a beginner with the right tools.
Parts.
Magstrike shell
Mega missile tank
Pump of your choice (I used a repco dual action)
5mm vinyl tube (I used the tubing left over from a Shotblast mod)
RSCB (I make them from 20mm pressure pipe. look up RSCB in the search box)
Tools.
Rotary tool (dremel)
Hot glue gun
Screw driver
The first thing to do is make a RSCB I won't go into detail about this as there are already write ups detailing how to build them.
Take your megamissile and cut the pump shaft down like so. It should be cut to a size that fits neatly into the magstrike clip space.
Next cut the end of the pump off and carefully glue it into the cut down pump shaft. Ensure you get a neat finish with a total seal. You must have a clean cavity in the pump shaft free of glue after this or your mod will not work.
Drill a hole into the cavity of the pump shaft to take the new pump hose. In this case I've reused some hose from a shotblast but a sturdy vinyl hose like 5mm pressure pipe will work just as well. The pressure pipe can be sourced from a home brew store as keg line.
Place the RSCB and tank into position then mark and grind the shell as required to fit the RSCB neatly.
The vinyl hose is pushed into the pump. I then sealed with a little hot glue to hold firmly.
The tubing is then pushed in the hole in the pump shaft cavity and sealed with hot glue. Be very careful to not melt your tubing with your hot glue (my gun gets really hot). Now place the whole assembly into the magstrike shell. I have trimmed the pump a little to fit.
I have hooked the trigger straight over with a couple of cable ties but neglected to take a photo, sorry. Wire or something similar would have been better.
The end result is a seriously comfortable blaster with good range, but not to OP, so good for general warring. I would put the power on par with a ShotBlast. Ranges are around the 120ft mark and the accuracy is good. The RSCB holds six darts and to achieve this I have moved the barrel quite forward of the T coupler. This dose create some dead space but I don't think it's noticeable in the scheme of things.
