I've been meaning to make this guide for a while. Since modding my first of these I've picked up FOUR others for anywhere between .99c and $2.99. Cheap no? Well these things are common in thrift stores because used with marshmallows they quickly become unusable because no one cleans them. If you happen to pick one up that has marshmallow cemented all over it, just soak it in warm water and it cleans right off.

Sorry in advance for badly focused pictures.

There are several versions of this blaster, the company that makes them kept changing their design and trigger mech. They are all okay but of the five I have I think I only have one pair of the same model.



So this is your Basic blaster. Notice the screws and the back cap by the pump. Okay now forget those. They are only necessary if you need to fix a non-functional model or plug your pump. More on that later.



This is the actual part where air comes out. To get access to this press in the buttons that hold the front grip on and pull it off. For this part you will need a dremel preferably but a knife may also work if you are CAREFUL.



Cut out the center of this piece. Cut until a half inch PVC coupler fits snugly into the front of the hole pushing it halfway back. If you over cut don't worry we will be epoxying this in place. After your 1/2" PVC coupler is in place you will need a 1" OD 3/4" ID O ring (#15 where I am) this we will put over our coupler and seat against the blaster like so.



After making sure your coupler is level and straight epoxy it and the Oring to the blaster. I used clear so you can see but whatever epoxy works for you use.



After your epoxy has dried, the grip fits back on over your coupler. You are done here unless choosing to plug your pump. Add your barrel of choice, like a cpvc breach or hopper. (This will work with a hopper by the way.)



To get to your pump screw off the back cap and pull it out. The pump in the picture is unplugged because to me its not necessary to plug this blaster. The OPRV only kicks in at super high pressure when its hard to pump anyways.

You may find it easier to use a 3/4" to 1/2" bushing, which should be about the same OD, and have a nice lip on the front.

Perhaps this is a newer version than I am accustomed to using, but I was under the impression that these had no OPRV as such. Instead, they use dead space in the pump to limit the pressure which can be built. If this version does have an OPRV, does the pump stroke match the length of the tube?

Additionally, if someone chooses to install a rocket barrel, these will shoot my rockets about forty feet flat.

How hard does it shoot and how many pumps do you recommend?

That completely depends on the version you have.  All of the ones I have are rather limited to the dead-space pressure, but that takes 4-5 strokes.
