Well if the scope came with the rifle... sorry to say you will have to get a new one. The one that came with my benji XL stunk and would shift after a few shots. I would look at leapers scopes. They are airgun rated and have been serving me well for years. Unfortunately those guns are gonna drive you crazy with accuracy issues. They are powerful but don't shoot well. Also try loc tite on all the mounting screws to the stock. (use the right stuff not permanent)Then clean the barrel. Mine was disgusting. Then just shoot a few hundred pellets breaking it in. By the time your new scope comes in the mail hopefully your rifle will have settled down. But I don't have high hopes. Sorry to be a downer.
