Canadian Airgun Forum

Finally finished the cz200 regulator mod that I started during the Christmas break.

Regulator is just a regular paintball one. Machined the adaptor and plenum out of 6061 aluminum bar stock. Did some calculations for burst pressure and the plenum should withstand around 8000 psi, just in case the regulator fails. Adaptor on the cylinder has significantly higher margin.

Set the regulator pressure to 80 bars to get more shots. Because the pressure is so much lower the hammer preload has to be reduced considerably. I had to use 0.8mm wire spring for the hammer spring. One side benefit is that the bolt is much easier to cook.

Since this is a paper puncher I tuned the gun to 500 fps and consistently getting 495 +- 5 fps. Didn't had a chance to do a proper shot string yet but I estimate the shot count to be at least 150 - 200 shots from 230 bar to 100 bar at 500fps.

GOOD job!

That looks very nice~ very special and performs as what you expected, right?

And refilling the air tube from the back now?
