I'm not really into milsim-type stuff, generally speaking, but I recently bought a box o' B2K3 and while I try to acquire the necessary replacement parts (wiring harness, misc. screws, etc), I've been thinking that this might be an ideal candidate for a project. Being that the "trigger" is nothing more than a microswitch which can be fairly easily relocated, it opens up a bunch of options. One of the front runners right now is modding an airsoft P90 replica shell to accept the Bushie's body. Something like this:

(NOTE: this is from a thread on the Tippmann forums, not my gun or even one I've seen in person)
So, the question is, does anyone have one of these P90s or know where I could get one cheap? Or, better yet, does anyone know where I could get some pics of the stock innards of the airsoft gun so I can get a vague idea of what would be involved in gutting it for this project.
