Thinking about something like this. https://www.opticsplanet.com/holosun-hs510c-circle-dot-open-reflex-sight.html This is for a PSA Freedom Magpul edition, so it has the FSB, so optic needs to either cowitness or lower 1/3 (preferred). This is for a person who will likely never actually shoot it, but it needs to be ready and can't require monthly/weekly battery changes. Considering MRO, primary arms, Holosun (don't know much about them but they get good press overall, plus the owner is a geek for solar panels and gadgets and stuff). A shake-awake optic would be cool, as long as battery life is measured in months or years. Also an Aimpont PRO would probably be fine or something like it. Input, ideas, suggestions, and mocking welcome.
