I am thinking about putting one of these on my Mini-14. Maybe a Holosun. The Mini only shoots to around 2moa on a good day, 3-4 moa on a bad day so it seems like a waste using a traditional optic. Thing is, my eyes need a side focus/side parallax adjustment. I haven't seen one of these red dot scopes with a parallax adjustment and am wondering why not? I can't be the only guy with older eyes.
