    Tuning O-ring failure, Kral Puncher Monarch

    Update: New fill probe was a success! Kicking myself for not trying it right off the bat when I ordered the o-rings. It seems like all is working well with the rifle. Filled it, shot it, and refilled it again this afternoon. Thinking I'll take it to a range tomorrow to get a little more in...

    Tuning O-ring failure, Kral Puncher Monarch

    What would be a good bet for aftermarket? I have tried sanding it, breaking the corners around the oring channels, and re inserting it. The scratches and dings there come back fairly quickly. Maybe it's the size of o-ring making it go in crooked though. Tomorrow I should be getting better...

    Poppet? Is that the valve out of the tank on the barrel side? That leak resolved when I got enough air into the tank. The tank will hold air without loss... but only up to ~100BAR. A burr had occurred to me, but I can't find it by visual inspection. What would I do to get rid of it if there...

    Tuning O-ring failure, Kral Puncher Monarch

    I have new purchased Kral Puncher Monarch from Krale.shop and have been having issues with pressure. This is my first PCP airgun, and the first time I've tried to fill it since getting it. First, it would leak through the barrel when I tried to charge it. I was told this might be an...
