I have no idea what this means...

Don't worry, knowing him I think he can make it work, ghetto style .

I may turn this into my senior project. After talking to my tech teacher, i will have to create each peice of my gun in Inventor (like down to ever screw) and THEN create the body to go around it. Dont expect to see this any time soon.

If you wanted to simplify it here is what I would do. 

1. Figure out the internals you want to put in it.  You will have to buy them, or use them from your stock.
2. Measure the internals with as much detail as you can,  draw everything down on graph paper in as much detail as you can.  If INVENTOR does this that is fine.
3. Find a local machine shop to cut the housing for your internals.  I would use two pieces of aluminum, one cut thinner than the other.  That way all your internals will be housed in one side, and the other piece would just be a cover.  The going rate (and I use the term loosely) at machine shop's I've dealt with is $85 an hour.
4. Take your internals with you, to give the machinist the clearest picture of what you want done.  I would drill and tap the holes for screws myself.
5.  After it's done, the chances of everything going in perfect is pretty slim.  You may need a few tools to help make your parts fit. 
6. The only major problem I can think of off hand is where your trigger will go.  To keep things simple I would keep all the external surfaces flat.  No curvatures except for the internal housing. 
7.  The rear stock will probably take some time for you to shape the way you want using a hand grinder.
8.  If you use AEG components, you might be able to wire the trigger to a button system.  If you use a springer style, sniper rifle components, I think it would be harder to do.

These are just a few quick thoughts.  There are so many more little details swirling around in my head, but I feel this post is enough for now.  If you like the ideas, and what to chat a bit about it, we'll swap #'s and I'll offer you a  little more insight.

Thank you man, but the last thing has me confused. I thought that with the simplicity of the bolt action design, it would be easier to create a body to house it in. An AEG would have to have all of the wiring (not hard but that means space inside the body) as well as a place to store the battery. Also with this gun the gearbox and motor may not fit inside of the grip like its supposed to.

by any chance Dom do you have some spare parts i can haz? if not I need to buy some.

If you use a bolt action trigger, you'll have to create a mechanical trigger to pull the actual trigger in the original parts. If you use an AEG, all you need is a switch and two wires. Technically, an AEG might be easier to work with. All you'd have to do is mount the gearbox, hopup, and barrel. You could feed BBs using a shotgun shell and 6mm tube, and you could use a V3 or V6 gearbox so the motor would be attached.

So for that build, what parts should i look for to buy?

[SteevoLS]

I'd start with the aluminum blocks as mentioned above. You'll also need a gearbox, hopup unit, and barrel. A trigger could be easily made from a microswitch or an existing AEG trigger. The shotgun shell idea is lifted from some other custom builds I've read about. They are small, easy to mount in a custom gun, and very reliable.

You really need to draw everything down on paper, from the scale that you want the housing to be, to the internals, to how you want it mounted.  If you can do a springer setup, and are not worried about fps to begin with, there are a lot of VSR internals out there that you could pickup cheap.  Like Steevol's said though, just thinking out loud here, it seems like the AEG would be the way to go simply because you can move a few parts around. 

I can't stress it enough though, you need to sit down and draw this out, and do some research.  If you're not familiar with the internals of an AEG or a springer, then researching that should be your first step.

Good insight so far, I just want to point out that the simplest option would be to, rather than build from the internals themselves outward, instead build from an actual receiver outwards, trimmed however you want as long as it still structurally sound. This would require less precision and you would not even have to have it fit in perfectly, it could be suspended by bolts in a very simple rectangular prism shaped cavity in the outer receiver you create.
