If I had access to a machine shop...

[Jackson]

Oh the things I would make...









Any guesses as to what's inside?

[Riddler]

hum, let's see. 

it obviously doesn't have onboard air or run on 12ies, but that doesn't really help narrow anything down.  i assume not an electro.  the springfeed comes in from below the breech, so it has to have that lower tube, but i can't tell what else is in there (if anything), so the gun can be either 1 tube or two.  that doesn't narrow it down by much.  the lack of a pump handle narrows it down a lot, though.  i also don't see any pneus so i assume not a 'cocker.  i don't think you'd go exotic with it, so the gun has to be either a blowback or a blowforward.  tippmann, spyder, icd thundercat, icd desert fox or automag guts all seem feasible.  the window on the side of the gun seems to indicate that it's one of the blowbacks.

Very good deduction.

The lack of a pump handle could be that I just haven't modeled it yet...

But that slot in the side is not for a charging handle (blow back).  It is for easy removal of the internals since the air line enters on the side.

Picture two yields a clue that with the above info should pretty much tell you exactly what the valve train is.

[Riddler]

what, the hole in the back that could be for velocity adjustment? 

i don't see any seams for a means of disassembly, but if that side window is for an air input, it could well be showing a sneak peak of the side of an AIR valve.

Whatever it is...it looks sexy and i want one

Im guessing, perhaps, a spyder internal?

The rendering doesn't show seams since all of the parts are modeled nominally there basically is no gap between parts.
But yes, that is a velocity adjustment hole to reach an Automag reg.

Here's a cut-away (shown with an X-valve because that's the CAD file I found online):



And you can see the three pieces the receiver breaks down into: the body (top, based on the AGD Extended Sluggo Drawings), rail (bottom, based on the Automag rail, also houses the spring feed and trigger group), and the stock attachment block (rear).

aha! a couple quick thoughts:
-if you get around to making the gun, make sure to use a stainless steel washer or 7075 aluminum for the receiver, or it'll mushroom out where the bolt smacks it.
-as long as you're going crazy with the design in CAD, why not just scrap the side window, air hoses and need for awkward tank placement, and instead stick a 1/8" NPT plug in the normal air inlet of the reg, drill and tap an inlet into the bottom, and run 12ies or constant air hidden in the stock?

Yup, SS washer would be definitely used.  That's in the sluggo drawings.

I honestly don't think that the tank placement is that awkward.  It would be mounted with a bracket similar to a PPS Hurricane.  Should balance over the trigger.  Also this would ideally take Mossberg 500 stocks so the end user can choose whatever stock he wants, folding, fixed, sawed-off, etc.  Though the air-in-stock option would be cool.  Would look a bit cleaner, but then there would be the problem with drilling and tapping the valve (difficult since it is round and stainless).  Also, the new NPT hole would interfer with the thumbscrew hole on the bottom of the valve.  But I could also make a replacement end cap for the valve to replace the reg and have it tapped out the back then use a secondary reg to control pressure...  But then how would you easily access the reg to adjust velocity...  Lots of issues that need to be resolved...

[Riddler]

Mossberg-style would be good.  opens the door to other options, too, like Hogue grips.

and i'm sure constant air would be fine... i've never had a 'cane, but i had a kp2-df that was plenty comfy with a bottle.  I just prefer the more elegant hidden tank or 12ie solution when possible.  If you tapped the bottom of the valve for an air inlet and couldn't run the hose past the thumbscrew, you could always relocate the thumbscrew location (again with the drilling and tapping) to the top of the gun.

It's not the thumbscrew but rather the hole the thumbscrew threads into.  It is at nearly the same position as the air input, just 90 degree off.

[Riddler]

Are they that close? Yeah, I'm at work and don't have one in front of me...  Well, relocate it, then! 

As long as it's somebody else's project, I'm all for suggesting things that I'd like, no matter how difficult and inconvenient they may be!

LOL.  Ass.

Yeah, the thumbscrew is just slightly forawrd of being on the same plane.  If they were on the same plane it wouldn't be a big deal, just drill out that hole.  But the thumbscrews is just far enough forward that it would perfectly bisect the threads of the new NPT hole.  If you move the NPT hole forward, you might make the wall around the on/off assembly too thin.  Overall I would rather not mess around with anything that holds pressure.  TK engineered it right.  Why mess with it?  LOL.
