Today, we'll be modding a Buzz Bee Big Blast, commonly referred to as a BBBB.

Materials:
A Buzz Bee Big Blast
At most a foot of 1/2 in. cpvc
The barrel extension from a Nerf Longsot front gun
Hot Glue gun
Hot Glue
Electrical Tape

Tools:
Hack/Band saw
Hot Glue gun(listed above)

Step 1: Disassembly/Minimization

On the front of the BBBB, there will be an orange ring connecting the two halves together. Pry it off by any means necessary. Once you get that off you can unscrew the gun. Take out the internals. Now this step may be a little confusing. Cut where I did. Actually, cut a little before where I did, then sand it down so it looks like the pictures.

Step 2: New Barrel

Cut the stock black barrel don so there is about a centimeter left. Then, sand it down on the outside so the orange barrel extension fits over snugly but not to snug or you could crack it. If it's too lose for you, stick it on and glue or tape it but, that would make this mod semi-irreversible. Cut your orange barrel extension to about 5 inches and stick it on. Now, get your cpvc and cut it to your desired barrel length 9-10 inches works well. Wrap your electrical tape around the end and where the barrel comes up to for an airtight seal.

Step 3: Plugging the Pump

Get your hot glue gun ready and fill in the hole on the pump head like the picture. Now you can only pump it 15 times or YOUR TANK WILL EXPLODE!!!!!!!! You plugged the over-pressure valve. I recommend 10 pumps.
