Auto on/off red dot

[44fred]

I'm putting together an AR pistol and need some recommendations on a red dot sight. As the title says, I'd prefer something automatic.
I've looked at the Sig Romeo series but haven't seen many reviews.
Trying to keep the price in the $400 price range.

I have a Holosun 403c, with the Solar power. Though I will likely NEVER need it in a closed door situation, I find that it sometimes has issues auto on in a lower (indoor) light situation. If I turn it on manually, no big deal.

If you look hard enough, you will find a 4moa Aimpoint H1 used for around that price.

You will not need an on/off anymore since its 1 battery for 5 years of continuous use.

An Aimpoint Pro is another option. It's also in that price range and is "auto on" (you just leave the optic on the medium setting and it will run for 5 years continuously).

Eotechs are auto-off all on their own, even when you dont want them to.

Not automatic: I have a primary arms micro dot that has been on .308, .223, 7.62x39, and it is still spot on. The dot is 2MOA. I have vortex, bushnell, and many others I have used and the PA micro dot is by far the most reliable.

Auto off: Vortex strikefire 2 with 2x but it is 4 MOA IIRC. If you have more to spend then by all means spend it, but get a 1-4x with a proper illuminated reticle for the money your willing to spend.

just my opinion.
