I have a Gamo Tac with the whisper barrel - pretty good. However, the rating is 1200 fps but that's with a very lightweight pellet that will get pushed from a mosquito flying around from the next block. The 10.5 grain pellet I use brings it down to just under 700 fps.
But most scopes that come with them are crap. For under $70 you can get a Hammers 3-9x40mm scope with an AO. The rings should have a base with a pin that gets trapped in the rail slot to keep it from moving. And you must use a scope that's a springer specific or the pounding will ruin a traditional scope. Good luck.
