How do I reach the air chamber?

[FlipShot]

is it possible to get the power tube off so I can clean inside the airchamber?? I remmember in that old azz automag video they used a C clip or something to hold the powertube onto the airchamber but my gun does'nt have this clip, I'm guessing cause it's a newer model.

The power tube used to screw on. Level7 on was a once piece power tube attached to the rest of the valve.

I suggest just taking the thing apart and rinse the bugger out. Good luck.
