Guys the gun can be borken down into basic parts.

Regulator / On/Off / PowerTube

There are very very few things that will cross across the areas to cause issues.

If the gun is getting a solid shots, good pop on the ball then there should never be a need to turn up the regulator ( the velocity adjustment ) to get the gun to reset.

Bolt stick is a function of residual air chamber pressure and the spring not being able to over come that. So I would check the hight of the spring to see if it is overly compressed. Next would be tuning using the Spacer kits. Outside of that you could have a tweaked Rail or Main body, I saw a lot of rental guns with slight bends to them from getting run into the ground.

height is fine. in fact all the previous problems appear to be gone now, but a new problem arrived.

this is a gun i'm running off 12 grams. occasionally, the trigger became impossibly hard to pull. is this a problem of liquid going past the reg and into the on/off area and then boiling? it was a really hot day, like 100 fahrenheit hot. this happens occasionally, and with both working shots before and after. the gun still appeared to work but i had to pull the trigger really hard and i'm not sure if it was because i waited long enough or if i finally pulled the trigger hard enough.

If the regulator is working correctly the CO2 shouldn't care anything odd in how it feels. So if you are loading the valve up with liquid i could cause a stiff trigger from over pressure but it should also vent if it gets over 650 psi in the valve chamber.

How is your 12g set up ?

horizontally above the reg. i know, i know.... it's a bad place.

venting seems to be what happened though, although i didn't hear anything through my mask.

Well it's not a little leak when it vents off.

And that is a horrible way to run a 12g set up, you are getting liquid spikes.

Well that may not but all of it. I would put N2 on it to trouble shoot the gun. Once it is working on N2 then put the 12g back on and see if anything changes.

in that case the problem is more confirmed then, i originally tested the gun with an hpa tank before using a 12g, and the problem only occured with the 12g. i guess i inadvertently tested it. thanks for your expertise!
