let me guess... you read pat roger's swat article?
pat is one of the most experienced users of ar15's that i know of... he see's very nice setup's everyday in the courses he runs... he sees a lot of gear in real use...
through his experience he has found that the rate at which eotechs fail is a lot more than that of aimpoints... not to say aimpoints never fail... but they do less than eotechs...
giffman (fr. ar15.com) and I went to the range a month ago... i was busy zeroing my aimpoint... and he was getting ready.... as soon as he turned his eotech on and fired his first shot... his eotech went out on him... i can't remember what he said acually happend but at the time we didn't know if it malfunctioned or the batteries just went out... either way... aimpoint has eotech beat on reliablity and battery life... and gifford quickly switched his optic to an aimpoint... but as i understand it he's going to give them another try on his new midlength build...
i do like eotech's reticle... its a little more smaller and i like that... but its reliablity doesn't justify it for me... i can make consistant shots with my aimpoint from 0-300m all day... and that is good enough for me... if you do just REALLY want an eotech... i'd recomend getting a fixed BUIS even if it slows you down... i have a flip up on
my aimpoint carbine and i keep it down for the most part... i trust my aimpoint enough not to worry about having a fixed BUIS... and if my aimpoint did fail within 25m's... look at the next paragraph
this last weekend at the range i decided to repeat
lumpy's ghost ring aimpoint down drill... and his experiement was repeatable... from 25's... i was able to make excellent hits... sometimes it was scarry how good it was...
... within 25m when no cover is availble for the action of flipping up my rear BUIS isn't usally allowed... you must place a round fast and accurately... this is where the aimpoint comes in nice with this ghost ring technique that pat rogers talks about... if i got enough distance/cover... the buis can be flipped up in a second...
i also don't like the errgonomics of eotechs i find it ackward to activate it... but maybe i'm just too used to my aimpoint...
