Sighting apparatus for use with a firearm that discharges ammunition having multiple projectiles

摘要

A weapon system comprises a firearm configured for discharging ammunition having multiple projectiles and a sighting apparatus integral with the firearm. The sighting apparatus outputs a beam of light having a generally round shape. The sighting apparatus is oriented such that a centerline longitudinal axis of a barrel of the firearm extends through the beam of light. The sighting apparatus includes a light beam size selector for allowing a cross-sectional size of the beam of light at a fixed reference location external to the sighting apparatus to be selectively adjusted by a shooter of the firearm to a plurality of different cross-sectional sizes.

主权项

1. A sighting apparatus adapted to be installed on a firearm capable of discharging shot pellet ammunition and slug ammunition, the sighting apparatus comprising:
a mounting bracket attachable to a firearm; and a light emitting unit coupled to the mounting structure, the light emitting unit comprising:
means for outputting a cone-shaped beam of light that is cone-shaped along a longitudinal axis thereof, defines a cone angle, and projects an illuminated sighting reference on a target a distance from the sighting apparatus;means for outputting a second beam of light at a central region of the cone-shaped beam, wherein the second beam has a dot-shaped cross-section and is surrounded by the cone-shaped beam; anda light generator outputting a column-shaped beam of light that is received by the outputting means of the cone-shaped beam of light to produce the cone-shaped beam of light and is also received by the outputting means of the second beam of light to produce the second beam of light so that the cone-shaped beam of light and the second beam of light are both projected onto the target and the second beam of light is at the central region of the cone-shaped beam of light.
