Re: cqb optics
The effective range can exceed 1K against paper or steel.
Build two ARs, one with a reddot for defense, plinking, carbine courses, etc, the other with a variable, for range work, hunting, whatever needs longer range or more precision. Asking one to fill both roles will require compromise.
I like EOTechs, they're real fast and simple out to 200. I have a magnifier, I don't like it, it adds weight, eats rail space, made me relocate my optic, the eye relief sucks, and it magnifies the dirt and debris on the EOTech glass, but it does increase effective range, I think it may be the worst compromise.
I haven't decided on a low power variable for my second AR yet but I'm not a whole lot slower with a 4X so it seems a 1 or 1.5X with proper reticle should be really close to reddot speed, but they do require a proper cheekweld. I'm thinking this is the best compromise. If you QD mount it you can pull it off and use your BUIS for household duty, they're more than adequate for engagements under 50'.
I don't like offset sights, tried them on a buddy's, tilting to acquire sight picture is not instinctive for me (a training issue I know), its also more weight (though minimal), more to snag, and something else to worry about dropping the rifle on.
Also I'm not terribly fond of the Vortex reddots but they come with a nifty screw on 2X magnifier.
Its really personal preference and what you're willing to give up, if you can try a few setups, even if all you can do is look thru them in the gunshop atleast you'll have some feel for it.
