I own both the Eotch 512 and the Aimpoint Pro.
Their price point is almost identical.
The Aimpoint pro seems to have some significant practical feaures the EOtech des not ( flip upo lens covers , 2 not 1 screwa to maint zero.. body more rugged, much longer batter life out of a lighter battery)
But the EOtech does work for me better in target aqusition especialy at ranges over 50 or70 yards the EOtechs reticle with point in the middle setup is superior performance wise and Holographics are an optically cleaner and more prcise technology to boot.
If your requirements set is essentially CQB only The Aimpoint wins hands down be cause its only 2 weaknesses realatve the Eotech mean nothing at well under a 100 yards.
if you want a CQB setup up that will perform in a pinch to 200 or more yards the Eotech is better.
And when it comes ot ruggedness its defintly not a fragile unit either and the alu armor on top is almost certainly even tougher than the body of the Aimpoint.
So if CQB is your near exclusive game, such as urban self defense, HD or urban SHTF Aimpoint PRO wins.
If you also want to go hunting and want/need a little bit better long range capability on top of the good CCQB both optics offer than the Eotech is your choice.
