I'm not having much luck lately, starting to pull my hair out. I have an MK4is I start to feel a bit of air coming from the breach as I understand the only thing it could be is the probe oring, so I swapped it out and I can still feel it, it's the correct oring 004 shore 90 is there something I'm missing.

May be the o-rings on the transfer port? I have had to change these on my Huntsman occasionally. How much air can you feel, I check mine with a piece of tissue over the breech, if it blows off when firing then I need to change the probe o-ring or running a few pellets over a chrony will show if you have a problem.

It doesn't blow the tissue off but it moves it a fare bit, tried another oring incase I damaged the first one still no joy.

Just changed mine yesterday. What led me to the problem was extra noise when fired and then when I single loaded it I put my hand over the breech and it definitely was felt. I had a heck of a time getting the old one off and it showed just a couple of small loose fibers but I guess that's all it takes. I thought my packet was marked with the size but it wasn't sorry.

The same problem I'm having JK. At first they gave a pack of 004 shore 70, went back had to order shore 90 in ended up costing me $33 for 12 including airbag not cheap. Replaced oring still got the same problem.

Cheers Strikey it ended up being the transfer port oring, I was a bit hesitant to pull the gun apart. Looks like it blew out on one side, thank you all for you're help.
