Recently I purchased a red dot sight to run on pistols. It's a Swampfox Liberty and the only pistol sight I've tried. I noticed that while using the optic outdoors there seems to be a red semi-circle under the dot. Almost life a reflection maybe from the emmiter. Indoors I just see the dot. So my question is if it's normal to experience this while using these types of sights on pistols? I've reached out to Swampfox as well and am waiting on a reply.
