what do you want to have behind your eotech?
troy- love their flip sights
lmt- nice looking solid buis
larue- solid with throw lever, have one and like it very much
arms- flip sight used in the past without a single problem
depending on what you want all of these are good sights that i have used.
some things you might want to think about is the controls of the eotech and if the buis will interfere with them.
a flip sight would fold out of the way but will need to be deployed in a time of need.
the solid buis will always be in the ready position and if they slow you down when you need to turn on you eotech it would be ok cause you have buis'!
again personal preference
