[Revise]Q. Will anyone here make me a proton pack for (any amount of money)?

A. No. GBFans and its members will not make a proton pack for you. It is in fact illegal to produce and sell complete replicas of proton packs but you are encouraged to attempt to build one yourself. Plans can be found in the Equipment section, and many parts are for sale in both the GBFans Shop and in the For Sale/Wanted section in the community boards. For anyone looking to purchase a complete proton pack please go to

[Revise]Q. Is it legal to Sell and make a profit from a Proton Pack?

A. No...well, that depends, if you have one that's already made and you want to sell it, that's ok, but if you mass-produce them for the sole purpose of selling them to make a living, that's a different story. The design of the proton pack is the sole property(copyright) of the designer/studio that created the movies, which in this case is Dan Aykroyd/Sony Pictures, if you were to make them to sell as replicas for any profit and got caught, that could constitute design/copyright infingement.

[Revise]Q. When the ghostbusters get ready to bust Zuul, Venkman readies them by saying?

A. The barrel extends via a mechanism built into the gun box, activated by a green lever that sticks out from between the gun body and the trigger box, seen here:


The exact mechanism isn't known, but "Playskool", one of our very skilled builders, devised a mechanism that most would assume the original worked very similarly.

Another member here, PeteVenkmanJedi, copied this mechanism, as seen in pictures here:

Many believe the twisting of the front barrel is what extended the wand. This is incorrect. The twisting of the front handle was for comforts sake, for the actors, and apparently nothing more.

A. "Let's show this prehistoric b**** how we do things downtown"

A: "Alright, this chick is toast!"..closely followed by:
"Grab your stick!"
"Holding it"
"Heat 'em up!"
"Make 'em hard!" (This has been controversial as some forms of the script have this or written as "Bang 'em hard"
"Let's show this prehistoric bitch how we do things downtown."

[Revise]Q. What are the tubing sizes on the Proton Pack?

A. 4mm (or 5/32") red on the gun tip from banjo to banjo
1/4" green on rear instrument bar of the gun from clippard barb to barb

1/4" blue from PPD to RH-50 resistor and from RH-50 resistor to top of Ion arm
4mm (or 5/32") yellow from small resistor on ion arm to Legris elbow on ion arm (some people use 1/8" yellow here)

1/4" Blue and 1/4" red on injectors to cyclotron base

4mm (or 5/32") red from Legris elbow on Cyclotron to Straight fitting on side of PPD (some people use 1/8" Red here )
4mm (or 5/32") red from PPD to HGA Legris elbow (some people use 1/8" Red here)

[Revise]Q. Where can I purchase a Hero or Stunt Proton Pack?

A. You can't really purchase a hero or stunt pack, because they aren't "on the market", a few of them are on display at Planet Hollywood an some other places.

As with most "where can I buy a proton pack" questions, the best, and only answer, really is continue to check the For Sale sections of this and any other possible GB's-related sites, such as proptopia, for packs that are for sale. Otherwise, build your own.

A few rules when checking boards for proton packs for sale:

Out of respect, do not approach a board "demanding" a pack, or anything in general. Be respectful and courteous and ASK about things.

Don't expect to pay less than $1500 for a fully built proton pack. These are big, detailed, difficult-to-build prop replicas, EXPECT to PAY.

Finally, the absolute BEST way to go about procuring your own proton pack:

Build One.

You can do it, it's really not that hard, especially with the given resources the world now has between this site and...well...this site. Everything you absolutely need is here and in your head.

Buy some materials, sit down, and get to work!! :D
