I just got my Aimpoint M2 a couple of days ago. The only other red-dot I've used was a BSA. I noticed that when the Aimpoint is on, depending on where the dot is in the optic, sometimes I can see a red ring around the inside perimeter of the optic. The dot stays put on the target. It's like the red light used for creating the dot is reflecting off the inside boundaries of the tube. So I have this huge red ring the size of the inside diameter of the optic, and a little dot in the middle somewhere. Sometimes, depending on head placement, I can see part of a big red ring, like I can only see the red light reflecting on the top half of the inside perimeter.
Does this sound normal for the M2? I have never noticed this on the BSA that I used. I haven't shot with the M2 yet, but it seems like it could be distracting. Just wondering. Thanks.
