7. A sight comprising:
a light source that projects a circle around a chevron on a single optical element,
wherein the chevron is visible to a user within a field of view of the user, but the circle is not visible to the user, within the field of view of the user, when the sight is in an aligned mode,
wherein the circle is visible to the user within the field of view of the user, when the sight is in a misaligned mode, so as to provide instruction to the user to realign the sight relative to the field of view of the user,
wherein the chevron and the circle are simultaneously projected by the light source for selective display on the single optical element in both the aligned mode and the misaligned mode.
