To put it simply, a red dot magnifier is a red dot sight with a magnifying positioned behind or in front of it. Since it does not give magnification, the red dot is appropriate for close-range shots. It may be put onto the gun for all activities to avoid emergencies when it must be fastened on right away, which might cause your lens to become misaligned.
