Kral arms shadow regulator air leaking
- Thread starter Rmils123
- Start date
The regulator is between the bottle and the rifle. You need to remove the bottle. turn clockwise to reduce or anti clockwise to increase.
Only 1/8 of a turn at a time. Re-assemble, refill and test. See page 26 of the manual.

Spilt it where the yellow arrow points. The reg adjustment screw is inside.
Mine was leaking by the small hole and I had to replace all the o-rings inside the reg.

Just loosen the pressure gauge a small amount until you can hear air escape. Leave it to drain. You may have to loosen it a bit more during the process. NEVER UNDO IT ALL THE WAY WHILE THERE IS PRESSURE IN THE SYSTEM.

Yes, I pinched the rifle between my knees and used both hands to unscrew the bottle.
When the bottle is out you must dryfire once to get the air out of the plenum before you turn the reg clockwise.

Sorry, I was offline for a bit.
I replaced the O-ring inside the reg and tried to get it back to where it was, but I think it is a little bit lower than where it was.
About 120 bar now.

I got Kral Puncher shadow locked to 15Joules , what is a maximum power I can adjust using method provided above ? I have attached picture with regulator gauge with tank filled to 230bar . I have opened that part which is supposed to be Reg , there is only one bolt in reg and nothing more , I was expecting some kind of spring valve. 2nd picture

Did you count how many turns it took to remove this regulator setting screw?
It only needs a quarter of a turn anti-clockwise to increase the pressure. then it needs to be gassed up again and the reg pressure checked on the regulator gauge. If it is still too low, repeat the whole process: degas, remove bottle, another eighth of a turn anti-clockwise. Then re-assemble and check the reg pressure again.
I would suggest turn the screw back in by hand until it just touches the tip of the regulator inside. then back off quarter of a turn and start from there.

My mistake I did not took any picture before adjustment of that reg screw :/ I had to unscrew bottle a few times ,and now I got 160 bar on regulator . Now I got about 25 Joules which is not great for this rifle , there must be some other limitation within it , any idea what is that ?
