1. A light dot sight (100), attached to a surface of a breech (200) of a firearm, and comprising:
a light source (120) emitting divergent light;
a partially transparent reflector element (110), which reflects the light of the light source wherein reflected light is focused to a point on a retina of an eye of a shooter,
wherein:
the reflector element (110) is formed by a lens having:
a convex front surface; and
a partially reflective concave rear surface;
the concave rear surface of the lens acts as a collimator for the divergent light of the light source (120); and
an undersurface (111) of the partially transparent reflector element (110) is anchored to the surface of the breech (200) by means of a fastener formed by an adhesive (150).
