See the link below and click on each rifle that you can afford to check the FPS also read the review under each rifle and make a selection that fits your needs and budget.

This question is a bit vague to be answered. What purpose do you want it for is the big question here. A Ruger 10/22 and a Mosin Nagant could both be had for under $500 (actually, you could have both for under $500), but each rifle serves a very different purpose.
