I have a Vortex Crossfire 2 in 6×18×44 AO on my CZ Precision and .17HMR have no complaints . The Muellers Jackalope has are also great scopes for the $.
Nikon just released today a P-Tactical Rimfire scope.Pretty cool. 2-7x32 and either a hash marked MOA or BDC 150 reticle. I also a fan of the Target EFR because of the parallax adjustment and 3-9 magnification.
