I use a Bushnell Legend 5-15x40 mildot on most of the legal limit rifles I have ever owned including several TX200HC's and I am delighted with them. The only thing to watch -and this applies to any rifle with a loading port or a break barrel-is that it isn't too long making access to the loading port more difficult or breaking the barrel impossible . Other than that most scopes will do so choose according to how much you are prepared to spend.
