Why does everyone give this sight low reviews? Its an $80 sight, if you want a perfect piece of equipment go spend $1500 on one. This sight has worked very well for me, mounted on a RRA M4 it has a perfect co witness with magpull flip up rear and A2 front. Its a good entry-level sight, in the future I might replace it, but I will still use it on another weapon. Sure some may have trouble with it, everything is like that, now be honest have you ever really bought a perfect anything? My experience with the sight has been positive, it holds a good zero (not hard to do on a quality M4) all the reticles all work fine, the circle with dot is my favorite. Just remember it cost $80 with tax, most professional level sights start in the $400 to $500 range up to $2000!
Pros: Very good for the price
