CraigH, welcome to the campfire. You can order scopes from Leupold's custom shop is the scope is not a standard over the counter scope. You can order a 3x9x40 with the #4 or any other Leupold scope with the #4. You save some on shipping since you don't pay for the shipping to the custom shop and the scope is built for you. I have done this several times for non-standard reticles. .
