I have a .22 avenger that’s a bit beat up and has a small leak. I replaced all the orings on the air tubes, but nothing else. I have the remaining oring kit that will go with the gun. Comes will the DonnyFL adapter, 2 mags and a sst. There is marring on the air tubes from the barrel band set screws and from using channel locks to remove the air tube components. Nothing too deep, so it’s still safe. The gun shoots fine, I just don’t want to deal with it anymore. $175 shipped.
