I did a quick search on site and I didnt find any threads that answered my question so Im going to start this thread to hopefully get it figured out. Im not trying to start a war between the aimpoint guys and the eotech guys or anything, just trying to get answers. I have owned eotech 512's in the past and never had any issues with them. Although I never used one in combat or anything, just casual range shooting. I have an aimpoint micro h-1 right now and absolutely love it. It is a fantastic optic. Now im looking to get another optic for a different AR i have and here is where my question comes in. I was thinkin about doing a SOPMOD Block II clone build (so itll be an eotech 553 tan) but ive heard alot of horror stories about the eotechs. Ive heard they have issues with the battery compartment poping loose and the sight shuts off. And ive heard the sight will pop off the gun or loose zero. If the sight has this many problems and it this unreliable, why would the Military choose it for the SOPMOD program? You would think that the military would have the same issues with theirs as all the guys posting these threads about this happening to theirs right? I just dont want to buy an optic, an expensive optic at that, if it is going to be a pile of crap. Does anyone have any first had experience with the eotech 553? Any military guys on here that have used this optic in battle? Before I shell out $700 I would love some input. Thanks
