I would recommend a Zeiss Conquest, there are likely the best bang for the buck going and superb clarity and optics.
The price won't break the bank either.
They have a fixed 4x , a 1.8x to 5.5x , and a 2.5x to 8x , which would be the ones I would look at getting for that rifle.If you want to put a scope on it, by all means do. It's your rifle and it never hurts to want to improve your confidence.
There are others that are cheaper but you buy good optics at the start and be done, or buy poor optics and which you had the better optics later on.
