THIS NERF GUN IS BANNED AT ALL MY NEIGHBORHOOD NERF WARS, NOT BECAUSE OF INJURY RISK, BUT BECAUSE IT IS CONSIDERED CHEAP AND OVERPOWERED. THE DART SPREAD IS PERFECT, IT TAKES 4-6 PUMPS TO PRIME, 4 DARTS TO RELOAD, ITS A PISTOL, AND NEAR FREAKIN IMPOSSIBLE TO DODGE.
So lets look at this sucker. First take that cool sliding breech and toss it. LIGHTLY press the black dots and slide it off.
THe pump only goes halfway down the shaft, and doesn't go all the way to the check valve, as the pumps rod is too short. It is important to replace it. Unscrew the back red thing where the pump is. Pull your pump out, and cut the plus shaped rod off of the pump head as close to the pump head as you can. Do the same to the handle. Take some 1/2"pvc, cut it to the same length as your pump, and glue it to the pump head. DO NOT GLUE THE HANDLE ON YET.
plug the pump
take the red disc with the + shaped hole, and throw it in your trash or scrap bucket. Slide the red threaded coupler and a piece of pipe that fits loosely around 1/2 pvc pipe. I found 3/4" works the best. This pipe is to stabilize the pump so it doesn't do this
it should look something like this
Now you can glue the handle onto the pipe you use as pump rod
and it should look like this
cut the end of the barrel off, about 1/2" away from the black dots. DO NOT CUT PAST THE BLACK DOTS.
Glue 4 pieces of CPVC of your desired length to the front of your blaster. make sure they are centered. Due to the high air release rates, there is almost no power lost when adding 4 barrels instead of 3, so i HIGHLY recommend using 4 barrels
seal it up with hotglue or something
Sleeve that ugly mess in a piece of pipe
And here is your finished product
Go out and own some face
Q: I wanna see internal pics! WAAAAAAAAAA!
A. The way this thing is laid out, taking internal pics is near impossible, and wouldn't show how it works. Its like trying to take internal pics of a hornet tank
Q: How does the release valve work?
A: Its a giant OPV. yes, an opv. it is opened by the air pushing on it.
Q: Are you on crack? do you even know what an overpressure valve is?
A. i refuse to answer that first question. Yes, i know what an OPV is. The opv is held shut by a vertical perpendicular pin. when the trigger is pulled, nothing is holding the valve closed, so all the air rushes out instantly
Q: My head just exploded, as i didnt understand that at all. please compare it to something
A: Your friend (air pressure) is pushing to try and open a locked door (the opv). He pushes and pushes, but the deadbolt holds it shut. you suddenly turn the key (the pin connnected to the trigger). nothing is holding the door closed, and your friend comes flying in the house, and falls on his face. That is exactly how it works
Q: how is it posible to fire 4 darts with such short barrels and few pumps?
A: the air release is almost instant. when pumped 10 times it sounds like a gunshot
Q: Im gonna single it, and put a really long cpvc barrel on it
A: dont do either, caus the seal between the release valve and the barrels has more holes than swiss cheese.
Q: if it has so many holes, why is it good?
A: the air release is INSTANT, and quick, so much that the air seal makes no difference. adding longer barrels actouly reduces range, as all the air is released the instant the trigger is pulled: even faster than backpressure tanks
Q: i have another question that isnt stated above
A: post it here
hope you like it

I get what you mean. The best way i could explain how the valve worked was comparing it to an OPRV, as the engineers told me it was a Modified OPV. However, valve is completely unique
Your explenation of a OPRV is not correct; I believe you are trying to explain the dump valve. The OPRV is what stops the tank from building up to much pressure so your tank doesn't blow up.
