I’m hoping someone can help please. I have a Crosman 150 pistol which I have renewed the seals in. It still leaks slowly from the barrel which I believe is the valve stem seal. I can’t find anyone who does a replacement that will post to the U.K. I emailed Mac1 Airguns who said he could ship to the U.K. but after emailing him again (twice) he’s not got back to me
I’m hoping someone on here has maybe had the same problem and can help.

Many thanks

Mark
