Re: Zeiss custom shop?
Not sure if it was the "custom shop", but I had Zeiss fit a 4-14x50 Conquest with target knobs. Took about 3 weeks and $120. The look and function was fine. Just look up their customer service number. If you are looking for a reticle swap or target knobs, ask if all parts are in stock before you send it off otherwise you may be in for a long wait.
