I only have a couple
Both Holosun optics

1 has a single red dot (shake awake, so no need to turn it on when needed)
1 has a chevron instead of a dot as well as a circle around it (also shake awake)

The circle helps with your presentation, ideally you only see the chevron and if you see any part of the circle, you adjust your hold until you only see the chevron (Holosun 507c-x2-acss — if I remember properly)

1 of mine is mounted on a plate you add after you remove your sight (www.outerimpact.com)

Happy shooting!
