Actually, Vintage, the SS2 uses a pressure-driven firing mechanism, sacrificing a little bit of pressure to release a second pressure store. There's a big difference between an SS2 valve and a linear valve, such as on a Supermaxx gun, in the same way there is a difference between Metalstorm and a traditional mechanical pistol.
I wasn't trying to get into details about how the gun works. I was just explaining how that just because a basic homemade has a tank, pump, trigger, and barrel, it isn't just a copy of another gun.
I guess the analogy could be made better with a homemade and a supermaxx.
Also, you're operating with a pressure-actuated breech in mind, right? Otherwise those darts aren't going anywhere. I'm pretty sure you know this, though, given your RF20 debate.
I actually didn't have a breech in mind for the pistol. I figured that if what Bobert says is true (that the gun has fairly slow ROF if the trigger is held) you would have enough time to pull-and-release the trigger before two air bursts escape.
So, Zero, you would pump the gun, load a dart, squeeze off a shot, load a dart, sqeeze off a shot, etc... until the tank is out of pressure.
By the way, by "pressure actuated breech," you mean a magazine that force-feeds the darts into the chamber with (for example) springs? If so, yes, that's what I have in mind for my other project.

Nice job Formerly Sane. It looks very nice. However, I dislike the tube coming out of the rear of the gun. Other than that, if you could possibly find the parts for it, it would be awesome.
