Works well but no lens cover - Aimpoint Micro T-2/H-2 & Comp 3X-C Red Dot Sight Magnifier

I got the Aimpoint 3X-C Magnifier with the flip to side mount for my AR-15 and I am pretty happy with it. The unit is pretty compact, the windage and height knobs work well, the lens is clear and crisp and the flip to side mount makes it super flexible when paired with a red dot. The height is just about perfect for co-witnessing with the Magpul Mbus Pro LR iron sight. The flip to side mount requires a little getting used to, since you need to pull it back and then flip it to the side, but not a big deal. The only criticism is that this unit comes without any type of lens cover. Time will tell if that will become an issue.
