At the range today, Guy next to me has a 'Black' rifle with what I noticed to be a Holosun sight,

I've heard of a few positive reviews of this sight but never saw one before,

Asked if I could peek through it,

There was a wow factor here for me, Green reticle really stood out, crisp and clear, extremely wide field of view..

Anyone here using one, your thoughts? Durability and so forth?

Auto dimming and auto shutoff?

At distance likely not has accurate has a traditional variable power scope, but for a fun gun, could be interesting.
