Weaver makes a ton of them, under 100$ mostly, but if it's a harder kicking caliber, I'd spend the few extra bucks and get the Leupold. for light stuff, a 50$ Leapers will do. the harder the kick, the better quality you'll need.
Has anybody but me noticed that the lower the quality of the scope, the higher the quality of the mount is supplied? Freaking Leaper's rings are built like tanks!
