Well I think eotech is tier 1 so....and no, not the 512
I've said this before that I wish I liked the Eotechs. It's grainy as hell to me and the battery life sucks. They also had the massive recall a couple years back. Anecdotally on the internet the durability is just not equal to an Aimpoint either. These factors are very important to IG so I'd give it Tier 2.
