Re: IOR OR LEUPOLD MARK4
I recently acquired a IOR SH edition, glass was flawless and an excellent scope. Only reason I parted with it was due to the magnification (needed more than 18x as it was gonna ride on a 338LM)and eye relief was a little iffy.
I sold it to a fellow Hide member here a purchased a new Leupold MK4 in 8.5x25 w/the illum. TMR reticle and never looked back. I had heard some warranty issues on the IOR's and never had that problem with Leupold.
In short, I went with the Leupy and couldn't be happier. Customer service has always been great with them and I couldn't say more. FWIW, that my two cents worth on the matter.
