All you need pay is whatever the VX-3 model you choose costs, plus $90 more. HEAD00O1 recommends one go this route.

As soon as we can box it up and mail it, we are sending Leupold a 4 power FX-II. They will convert it to the CDS dial, and engrave one dial with the ballistics i include with the scope. For this work, it will cost me $150.
