RE: Leupold,New or Old
The vari x III line didnt change it' s name. the vari x II' s did.
They are referred to as vx1' s and vx II' s.
I have a vari x II and vxII 3x9x50 and the differences are that the vxII has click adjustments.
I wouldnt worry about getting the newer version they are great scopes old and new.
