The Ruger Impact Max Elite is a great budget priced air rifle IF you smooth out the trigger and replace the junk scope that comes with the rifle from the factory.
I purchased mine about six years ago, I modded the trigger with a lighter spring and pot a UTG Bug Buster variable scope on it, it shot great from the get go, never gave me any problems, I gifted it to one of my adult sons about three months ago to make room for a new Diana two fifty .177 cal. air rifle (another budget friendly air rifle).
I have about a dozen or so air rifles, of those a little over half are lower priced models and all have been reliable and accurate with a bit of attention.
In my opinion and in my experience when you purchase a budget priced air rifle it's unrealistic to expect it to be perfect in fit and finish, but most of them have the potential to be good shooters, you just have to bring out that potential in them, my advice is to just shoot it (be sure to clean the gore good before shooting it to get the rust inhibitor that they put in them at the factory (it will spoil the accuracy if not removed), it may take a full tin of pellets to break in, but if it's shooting OK I wouldn't spend the money on a gunsmith, it'll get better with use and your learning how to shoot it.
