Kahles CS was handled by Swaro in years past, which was very good.
How is Kahles now handling their CS?
I have a Kahles 2-7 rimfire on a Cooper Classic .22LR. It's about as fine a squirrel rig as one could imagine.
Agree with the Z3 duplex being a bit too fine. I would also agree that the VX-3 is pretty close and may be a better value, overall, for the buck. Leupold CS is top notch and the Leupold duplex is about ideal for general use.
