I am attempting to find a set of iron sights to compensate for a loss of vision. I have tried Big Dots, and Tru-Glo TFOs. Both systems work to a degree. Both systems are far from ideal. I am familiar with the Ameri-Glo Hackathorn sights. I have ordered a set of Speed Sights. Are there any other sights that I should be looking at? I am not yet sold on the RMR setup and would prefer to try and find a iron sight solution.
