Heres some pics for anyone interested in the guts of this thing.

Sorry I was an idiot and didnt take pictures of the actual guts guts...



http://www.takiweb.com/~killtippy/shi/c3/c3_1.jpg - KInda trying to show how it fits in your hand. Or something.


http://www.takiweb.com/~killtippy/shi/c3/c3_2.jpg - Size comparison to the 98


http://www.takiweb.com/~killtippy/shi/c3/c3_3.jpg - Looking iniside the weird bore-drop barrel. The back end is rough, but the actual bore of the barrel is very very smooth. You can also see the not-quite-adequete anti double feed.


http://www.takiweb.com/~killtippy/shi/c3/c3_4.jpg - The fuel injector valve, manual says its one of the main things to keep clean of gunk.


http://www.takiweb.com/~killtippy/shi/c3/c3_5.jpg - After opening the halves.


http://www.takiweb.com/~killtippy/shi/c3/c3_6.jpg - Its pretty idiot-proof. All the actual guts of the thing are locked up in the practically bulletproof chamber. The chamber is solid milled aluminum, very well made.

Now for info and stuff, copy/paste from my post on Tinkers Guild

Ahoy guys,

Just got my C3 today from Tippmann, and of course the first thing I did was dissasemble it. I dont have any propane laying around, Ill have to hit up Meijer tommorow for a canister and a 200rd thing of paint.

Anyway, First impressions:

Its heavy. Not super unwieldly heavy, but definately a chunker. Theres a ton of composites used on this thing, but in my opinion the only part of it that feels "cheap" is the pump handle. Its really cruddy chinese-toy quality plastic. All the other plastics on the gun are very solid composites.

The only actual solid metal part of the gun is the combustion assembly. Its extremely well made, solid machined aluminum. Thats where 90% of the weight on the gun comes from, this thing is literally bomb-proof (no pun intended).

As for maintenance and such, it seems pretty well thought out. There is a fuel injector valve underneath the barrel that comes out with the removal of one snap ring. Basically a big cocker switch, the manual reccomends checking the o-rings for gunk and damage every so often. The guts of the firing chamber are fairly easy to get at as well. Removing the gigantic velocity screw from the back end allows you to slide the guts out the back. Again well machined aluminum.



Now functionality. I was figuring it used the combustion incidentally to compress a gas piston, and using that to fire the ball. Well, I was wrong. The propane combustion itself drives the ball. As I can tell the firing process is

User pulls the pump back, this clears the chamber of the gas from the previous shot. The pump stroke is about 1.5-2". On the final quarter inch or so, the pump arm buts up against the fuel injector valve (brass cylinder under the barrel, you can see it in the pictures). This allows a small burst of propane into the firing chamber.

When the user pushes the pump back, I believe (not 100% at all, the front end of the chamber is rather difficult to get apart) the fuel/air is mixed as it passes through the giant piston that the pump moves.

Trigger pull activates an electronic igniter, combustion. This is where it gets interesting, there is a spring-loaded plunger on the back end of the chamber that gets pushed back by the combustion, exposing the barrel pass-through. The velocity screw adjusts spring tension on this plunger, acting something like a mechanical dwell. The gasses from the combustion then directly propell the ball out of the barrel.

Dag on that thing looks bulky and heavy.  I wonder just how hot it gets when firing.  I saw the manual and it warns that it will get very warm when firing.

so l33t. and let's just state this right now. Enos > Rambino

and i quote "<Enos> He got serial number 386, mine is 382"

we tossed a few ideas around in chat while enos was quoting the user manual. this might be a nice winter gun.

Even though I don't like the idea of propane usage for a paintball marker, the combustion is so fast, there's little to no time for the aluminum to get hot enough to release any gas.  Even at high rates of fire (remember this is a pump), I very seriously doubt it'd get that hot, extremely warm, yes, hot NO.  They'd never be allowed to market it, if it did.  Even my spudguns, which have a lot bigger combustion than the C3, barely get warm to the touch.  It's barely enough to burn a potato.  It singes plastic bags (I use these for testing), but that's about it.

I personally have no desire to get this gun.  I think it'd be cool that you'll get more shots per tank with the Propane, but the size and look of the gun throws me off.  I'm actually getting ahn SL-68 II at the moment.  Can't wait, and I'll get pics posted when I get it.  Custom Painted and Modded by Tigman.  Great guy.  Sorry I haven't been around as much guys.  I've discovered that I actually do have a life!

For 50,000 shots, I could care less what it looked like.

I'm still a little confused on the point about how combustion actaully fires the paintball. Nevertheless, nice work Enos.

I believe the combustion fires a piston, which in turn pushes the ball.  I could be wrong.  Do a search, there has been a lengthy discussion and educational session on the workings of the C3.

Uhh, actually it's right in Enos' article there...

Man that thing is a beast!
I want to at least shoot it some time though, to see what it's like.
That's sweet that you got one early. Never sell it!
