I used a UTG Bugbuster 3-12x32 for a short time when I had it set up as a carbine, but took it off because the scope interfered with with loading the pellets. It checks all your boxes and would be perfect for the pp700 IF it could be mounted far enough forward to clear the loading port. Alas, it can't. I just mention it as a warning for any scope you might consider.
If needing magnification, I've found the best option is a pistol scope. The magnification range is small enough that you don't need to fiddle with focus and it can see just fine at short ranges.
