Yep, thats my thread on my G&P brand Eotech 552 clone. There are MANY various clones,and I can only speak for the model that I personaly own, If what Im reading is true then the G&P clone was "TOO" close, and they were actually sued by Eotech themslves.( lawsuit pending) My Eotech 552(G&P version) has been fired for 2 more bulk packs of Federal since that last post, one pack was a 375 bulk pack, the other was a 550 bulk.
Add that to "around" 400 and some odd rounds I ran through it when/after I sighted it in originally, and you get 400+375+550 for a total of 1325 rounds in the past 3 days and it has held a PERFECT zero so far. Im shooting at distances between 60-125 yards and its the same now, as when I first sighted it in a few days ago. BUT I am not sure if all clones are this way but my version has the markings( up/down- left/right) are reversed as in up/down is left or right. If you want pics of the sight, then here are a few of my rifle( old pictures, but the only differnces is I have replaced the iron sights for Magpul flip up MBUS)
