powermaster 760

I have a older 760 with the brass probe. I get a lot of blow by. Is there a modded probe with a oring?  Or should I cut one in?    Thanks  Den

Yup, they all do that. No one is making a modified probe that I'm aware of. You can turn a groove in the bolt and o-ring it. It's been done. Or shoot it as it is and call it the personality of an old airgun.
