Not sure but a quick call to their NH service center, where the work would be performed, on Monday would let you know for sure. The numbers are (800) 468-3450 or (603) 287-4830. Post back when you find out so others will know.

YES. I know that the PMII DT (Double Turn) scopes are "upgradable" to MTC, but I'm not sure about the ST (Single Turn) scopes. I liked the MTC on my Premier 5-25X 27 MIL DT MTC Gen 2 XR, but don't have any experience with the PMII MTCs'.
As <span style="font-style: italic">Rob01</span> said, call S & B on Monday. Call or email Mark Cromwell for a quote. Mark has always been very responsive whenever I called or emailed him.
