I just dissasembled it and adjusted the reg. I took a video. Forgot to take pics or measurements. The Reg has 2 different thread sizes on it. Its the thing with the pressure guage on it. It screws in between the main tank and the plenum...then is the "action" part of the tank at the end. There is a 3mm allen key in one end. I gave it one full turn exactly CCW for more power. I will report how many FPS it got me. I'm at 890fps with 14.35gr now. I'll shoot it later today.
Degass the gun by loosening the air gauge once the stock is off. Then the tank section uncrew easily by hand. Remove the barrel band before removing the tanks. The thread protector needs to be unscrewed as well to slip the barrel band off.
The OD of the tank is 32mm.
