Was gonna go that Leupold route last year when I got my CZ-455 but the shop where I got it had me check out some Vortex stuff they had although they had some Leupolds in stock also. Took a Vortex outside to play with it under real world conditions and it impressed me enough to buy it. So now the CZ has a 2-7x Vortex on it and I'm real happy with it. 2-7x is what I have on my 10-22 and it's a good fit for what I do with a rimfire, ( small game and informal plinking, mostly). It's a lot more "budget friendly" than the Leupold and while I'm basically a Leupold guy I gotta admit that the Vortex is a real good deal for the money.
