Drill or dremel
Saw or dremel
Adhesive strong enough to hold pressure (epoxy, pvc cement, gorilla glue? etc)
Secret strike pocket blast $0.25 from a thrift store, 2.99 full retail new.
Tank: Vinyl tube or tube or some kind ~6-8in salvaged from fish tank, estimated cost ~$0.25
Barrel: CPVC with clearance for a dart ~17/32 ID ~1.5in $1 / 10 ft lets say ~$0.10
Remove the four screws and open the shell
Drill a hole big enough for the tube on both sides of the tank. The tank is the first cilyndrical section after the trigger section (the one with the hole in it).
When doing this be careful not to drill too far or you may damage part the triggering mechanism which is the plastic cylinder inside the pressure chamber you seen in the picture.
Insert tube and glue into place on both sides of the tank.
-When doing this make sure you the tube isn't touching the triggering mechanism inside the pressure chamber. This can cause friction which makes it harder for the valve to close when pumping and hard for the trigger to open the valve when firing.
-Make sure when gluing that you don't accidentally have any glue that will dry connecting the tube to the triggering mechanism.
-Make sure to allow glue to set before you pump it up
-The tube has now extended the volume of the tank
Get a piece of CPVC you can jam into the end of the stock barrel. Pretty much anything with around 1/2in can be muscled in.
You want to get something that is as snug as possible around a dart, but still allows a dart to move freely though it. I try to look for something that will hold a dart unless I shake the tube.
-Cut a piece off at roughly a 45 degree angle so the longest part is about 1.5in. The length and the angle don't have to be precise at all.
-Jam the piece in the end of the barrel so that the angled end of the cpvc matches up with the angle of the front part of the barrel.
**I've seen some write up on over pressure valve plugging on the sspb but the one that I had I actually broke this stock because it had no OPV. I'm not sure what the situation is for this but this one didn't need plugging**
Stock range ~15-20ft? /w streamline (mine was used, not sure if this is the range of a new one)
Modded range ~70-75ft /w streamline (Conservative estimate. Can't test outside now)
I know people have done tank expansions and barrels for this thing before but Ive never seen it done quite this way. I tried to keep it as simple, cheap and easy as possible.
