I think Leupold charges $149 for the M1 dials.
I bought a set of the Stoney Points and wasn't happy with them so I took them off and sent my scope to Leupold and had the M1 dials installed.
If you like the dials you buy from Dave Wilson and want a second set, let me know.
Thanks for the back up. You will also have to add shipping.
If you have any questions, call Gabe Lang in customer service. Gabe will take good care of you.
Here is a pic of my VXIII 2.5x8 with the M1 dials.
