The magnifiers reduce your field of vision plus also manify the size of the red dot. I am planing on getting a separate Nikon 4x scope for $99. There are mounts that allow you to have the telescopic sight on top and your red dot off to the side so for close shots you just rotate your rifle a little bit and now have your red dot in front of your eye. However, since this is a .22 I see no tactical or defense use for it unless you have nothing else to use so swapping scopes makes more sense and would be cheaper.
