I use a trijicon reflex, but that's just me. No batteries required, window shooting and not tube shooting, and I haven't been able to break the one issued to me for 2 years now. I like it so good that I bought one for my personal rifle.
It's not the newest and sexiest, but it works quite well and is truly parallax free as far as you can effectively shoot with it. Not great past around 200m, cause the dot masks the target. That's why I co-witness with my irons, though.
