Outstanding Optic

I bought my first FF3 several years ago for use on my 3" 12 ga. O/U turkey shotgun. It has performed perfectly and I bought another for use on an 870 SuperMag. This optic weighs next to nothing and performs way out of its weight class. It handles the recoil with impunity battery life is outstanding (still using the original battery after several years use) and the zero has remained rock solid. Its adjustments are precise FOV is unlimited since you can shoot with both eyes open it is quick on target and the 2 MOA dot allows for precise shooting and it is parallax free. The dot is clear and sharp as well as being easily viewable even on the brightest day. My only criticism is the Mickey mouse cover. One fits tightly but the other one will fall off if brushed up against anything and goes flying if left on while taking a shot. Even though the one fits more tightly I don't have any faith that it would stay put while shooting a 3.5 inch turkey load or if walking through heavy brush.
