Leupold Retrofit Question - BDC
Everyone please pardon my ignorance on this as Im sure there is a very obvious reason but I cant figure it out.
I contacted Leupold to ask about getting my VX3 retro fitted to have a CDS type system installed. Apparently I would need to send the scope in and they would need to install a BDC dial which is $90 and then create the CDS cap which is $60.
It appears that the Kenton Industries TTC knob can be installed by anybody.
What exactly is the BDC dial???? Mike
