Here are pictures, as promised.
(I thought the gun looked absolutely hideous with a black stock, so I painted it. In tan, its absolutely sexy.)
Here is a pic of the gun with the mag in and gas rig attached.
Here is the gas rig (assembled, missing the magazine) attached to the CO2 canister.
The regulator and dovetail mount assembly for the gas tank by itself.

I tried to get a good shot of the gauge I'm using right now (going to replace it with a more precise one as soon as I have enough money to be able to justify spending on something I don't *need* to replace, but would make things easier - this one's junk for our purposes and came with the regulator).
Really, not too much goin' on here. By far, the simplest thing I've done to the gun was install the gas rig (best $100 I have spent on any one gun, lol). FPS is 522 with .20g's; I expect some Madbull .36g's tomorrow (been using .28/.30g's (TSD/KSC Perfects, respectively)), and I have a chance to screw around with this thing this weekend. What brand .40's are you using?
