My buddies new kral puncher mega is leaking air out off the barrel/ breach,the gun came with o rings but I don't know which one to replace,took the gun apart and can't see anything visibly wrong,any ideas guys?
The fact that the air is coming out of the barrel and breech means it has to have something with the main valve, the first thing I would check would be the valve seating and if there is debris blocking its closure or bent.
The main valve is the piece that's threaded into the air cylinder that threads into the breech block,correct? Never took an air gun apart before,but it does not seem that complicated.
If you've never taken an airgun apart before, I wouldn't advise it without understanding the ramifications. The most important one is making sure the gun has been FULLY degassed. If it isn't, you're in for a dangerous surprise!
Yes ,I understand your concern ,but I have already taken it apart and reassembled the gun,should have said never taken one apart before this one,I have understood the degassing procedure ever since my marauder came with a degassing tool years ago.
