I have two Dr Optics's and an Optima.
Anyway the Dr is a 7MOA MilSpec version versus the 3.5MOA Optima (I cant tell the different)
Dr has Glass and a polarized face - battery life?
(they say a year for the Dr but its supposed to be better than the Optima and that has been running since 2002 inc two trips to Afghan one on a 870 and once as a CQB sight on a sniper rig)
I wished Mark made his iron dot as a stripped unit for a Dr...
but one is going on a TA31 and one for a 34mm S&B on my AR10
It not much of a review -- since I have not had a time to shoot the Dr's or see if they keep a zero.
