Micromag troubles

Ive read the stickies regarding everything I needed to check on my gun and I still can't get it fixed. As soon as I air it up it's leaking air down the barrel. When I apply any pressure to the trigger it instantly leaks out the back of the reg. I checked my sear and it's still got a nice sharp edge. I ordered a parts kit and replaced every o-ring in the gun, the reg seat, and even the bolt spring! I triple checked my sear pin and there is a slight gap between it and the trigger just like there is supposed to be. Also when I pull the trigger it doesn't attempt to fire. It just transfers air out the back of the reg instead. I need some serious help here guys! Any other info you guys need? I'm using a high output compressed air tank as well so that's not the issue. Any help would be greatly appreciated as when I bought this gun it was supposed to be in working condition and came to me like this instead.

how far in do you have the velocity? what (exact) input pressure are you feeding it?

I have adjusted the velocity to every possible position in an attempt to figure if that was the problem as well. The standard output on my my tank is 800psi. I double checked it and I have the on/off pin put in correctly with the end that has the groove down.

That sounds like the reg piston is bad. I had one do this as well, there is no rebuilding the piston. They are available though from agd for around $20.

Or did you mean this part? I think this is the one you are referring to after I read the description of what this parts purpose was in the gun.

Are you trying to run a L-10 kit on it? If you're not, and you're on an L-7 bolt, PM me your shipping info and I'll give you a reg piston. I'm pretty sure I have a couple extra.

If it is a lvl 10 upgrade, you might have the older reg that can't handle the pressure. I had one do the exact same thing to me and the new part cleared it right up.

How's the reg adjustment working? Is it a stock reg adjuster? If you back it off does the leak stop?
