Exactly what I originally thought, Justified.

Perhaps something simple. Each time you pull the trigger, the number goes down. If it's set to full auto (3-Round Burst), it goes down by three. Wiring onto the contacts? Mag reloading could reset the counter, via some magical device that can tell when something is inserted, and when something is removed.

I thought about this, but what happens if a partially loaded mag gets inserted? I think a sensor is the only good way to do it, building the mag more like a pistol mag than a rifle mag and having the gas supply for a Fusion Engine in there to use the rest of the space. The mag'll need to be custom made for looks, anyways, so why not?

For the ammo screen, I was thinking to have a proper 36 shot clip, and have the spring feeder like most gas pistols have, and attach a linear potentiometer hooked to that small pusher-plate. Have a connector on the mag and another inside the meg reservoir, going to a small microprocessor (arduino lillypad?). since it then knows how far the feed assist spring is compressed, some simple programming lets it know how many BB's are left! this way I can half-load it and not screw it up, as well as not needing to have a reset switch. Yes, I know that this probably means designing a custom mag, but that's kinda the point of the project; do as much custom work as possible to learn (not to mention making a wicked cool rifle)! For the mechbox, this is where I have very little experience... can someone please explain the difference from a v2 to a v6? and the only thought I had was to use a PolarStar Fusion Engine, or some custom pneumatic circuit, for both increased reliability and better sound/response time (while still having semi-full auto, to my knowledge lore wise the gun has both). But please tell me if this is a bad idea or not, like I said I have little experience in this area Lastly, lore wise the upper receiver seems to be a titanium alloy from what I can info I can find (cost may force a strong aluminum alloy, but we'll see ), while the bottom looks to be a plastic composite of some sort (glass fiber reinforced pollycarb?). I intend for this to be a 1-2 year project, and over that timeframe can MAYBE afford to put up to 2 grand into it (SPREAD OUT!!!!! no one $1,500 part I have nothing else to say), so lets' talk in the idea of "if it's worth doing, it's worth overdoing" These guys are totally right P* is the way to go if it fit's into the budget. They are new enough that I didn't even think about it. der... I don't know about that potentiometer idea. The mag would have to be single stack for sure. Most AR mags the tube in the mag is wider than a bb. This would give you inconsistent readings. With a properly sized tube it would be more do-able. Even then though I'm not sure as to what sort of accuracy you could get. I'm not an electronics guy really (more into software) so take what I say with a grain of salt. It sounds like a cool idea though. The other thing is when the resistance is on a border line your ammo count would flip back and forth. This could be dampened with some hysteresis but then you might lose accuracy. Maybe instead you would wait for a new mag to be inserted and do a best guess based on a look up table. From there you would wait for a drop in resistance by X amount for a round to go through. Or the ammo could still be hooked up to semi/burst/auto switch and it could use that to count down rounds. If it didn't work I would have a reset switch that get's closed when the mag is inserted. Then you just have to look for a open/close event to reset the ammo count, no manual button press. Not sure if the "real" thing is suppose to have a bolt release, that could be used also. I read the books, but I can't remember squat. I think that a linear pot should be accurate enough, at least the one's I've used in the past seemed good enough for the job (just gotta get the good ones). And yeah, good point on the tube, I'll have to keep that in mind when I design the mag! and while I think I can design it to not need a reset button, your right and having the bolt release (or ejection port with the hop wheel if it doesn't have a bolt release?) hide one is probably a good idea. and thanks all for the great ideas! So, it looks like fusion engine is the way to go. So... anyone know much about them? Like how hard it would be to put a decent air supply in a rifle mag, like if it replaced the ammo reservoir that's usually on high-caps? Or what the dimensions on the thing is, so I can try to design the body to fit it once I get that far? Thanks again! ;D

You probably won't be able to fit the air inside of a standard mag. Chances are, unless you make custom mags, very hard on air in the riffle mag. As far as I know, the tanks for the things are pretty damn huge, and they use an outdoor system unlike a GBB rifle. Think, 5x coleman tank size. +/2

Just keep the air supply in the tanks. They aren't that big at all. The larger ones can easily fit inside hydration carriers, and the smaller ones I have seen fit into utility pouches. Since it's bull-pup, just have a hole in your stock somewhere convenient and run the hose through there.

Maybe you could put in the stock of the gun. How wide is the gun going to be?
EDIT: A 13ci tank is about 2" in diameter.

EDIT: A 13ci tank is about 2" in diameter. not sure how wide the gun will be, that's the only demminsion I don't have and the stock is where the gearbox will need to go, it's a bull-pup and I don't know if I could easily have the gearbox away from the mag well. maybe a small bottle could fit in the foregrip? it looks kinda rounded and large... Here's the first CAD drawing, btw, just 2d but it is to perfect scale (entire gun is 89.9cm long, to give an idea of size). I still have a long wat to go before I have functional 3D designs! edit: thin maybe a dumb question... but why does the forum change any common social acronyms into weird phrases? I've had to fix that a few times now

What we're saying though, is that with the P* you only need the cylinder which will go in the upper part of the stock. There should still be a good amount of room in the lower part, since you said you would be using smaller mags, too.

Oh, okay. That makes more sense, I'm still thinking in terms of fitting an entire v2 shell in there... well, I like this idea, but how hard would it be to structurally mount the guts of the P*? would I have to buy it first to be able to look at it and design the internal spaces around it or is there an easier way? yeah, this is the kinda stuff that I need help with, and I greatly appreciate it! ;D

Quick little idea, not terribly relevant to the current subject.
Carry-Handle Mount on the top (/carry handle) for the optic.
Seems like a nice rubberized hand hold would be nice as well. Any thoughts on how you're going to do the mag-well/feeding? Maybe modify some standard mags, or build your own.

On the topic of random stuff, anyone know a small, strong flashlight (120+ lumen LED?) that I'd be able to take apart and fit the bulb assembly into the tube under the barrel? I think that'd be really cool to have, and I don't know what else that tube is for

You know, if you have the space, why not jury rig a light/laser combo? I mean, usually, you probably won't ever use a laser, but it'd still look amazing.
