PY Air's website says this is an adjustable regulator, but there is nothing in the manual about it. Can anyone tell me how to safely adjust the reg? I'm guessing I take the stock off.

Thanks!

No pics but it's easy to do. Remove the stock, degas with the degas screw, unscrew the airctube from the plenum, remove the reg and adjust ccw to increase, cw to decrease pressure.

Yeah. Can you get measurements also?
I'd like to know if the Huma regulator tester could be used to test/set them.
I'd also like the measurements as Huma will build custom regs if you provide those.
Or Buy the unfinished Huma and turn them down yourself.

I'll see if my spare G2 reg fits the air tube as well.

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.

Is there a way to adjust the HST? (Hammer Spring Tension). I got the reg maxed out to the point if I turn it anymore the velocity goes down. I'm at 852 FPS with 18gr JSB and 895 FPS with 15.89gr. I think thats as good as it gets. Unless I can adjust the HST and squeeze some more FPS out of it.

There is a allen key right here. Could turning this be my HTS?
