Hatsan 95 Vortex QE in .22 cal. Will be replacing the scope quick, fast and in a hurry as soon as I find one springer rated!
The included scopes are usually junk and don't last long. If all else fails, have a look at something like a UTG Bugbuster. Short, air gun rated, have a good warranty and many shooters like them and a lot. They're also usually under $100.
Like Bear mentioned, clean the barrel as well as you can, check the stock screws, shoot it a bunch and enjoy.
