Scope suggestions for Walther G22 carbine?

[RoyRogers]

I just bought the Walther G22 package in black with Walther laser sight--so far, so good. But there's another G22 package that comes with a 4x20 scope, which unfortunately my dealer wasn't able to find otherwise I would have gone for that one. I'd still love to find either the 4x20 scope or another comparable model. Anyone know where to buy an "original equipment" 4x20, or have a suggestion for a comparable scope that would be a good match for the G22? Thanks in advance!
