I run my Eotech on a railed handguard with my A2 upper. It co-witnesses OK with the irons, slightly less than half (a bit higher than I'd like). I haven't had any loss of zero after ~500 rounds. Maybe I'm just lucky it hasn't shifted yet but seems to work...
It makes it kinda nose heavy, but I like to wrap my hand around the front of the magwell in lieu of a forgrip, and it balances pretty nicely like that. A bonus is I can turn the sight on with my thumb without moving my hand.
