Despite my feelings about the Retay 135 in .22, I'm going to keep using it and maybe replace that horribly crunchy spring, maybe a spring that is intended for a 30mm tube.I chose to go down this path because Retay airguns are often really cheap on amazon, it was eating me inside not to buy one, I mean two, curiousity has been satisfied.My replacement should be here on friday, it will be interesting to see in what ways the second airgun differs from the one I just worked on.
