Abstract
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.
Claims7
A sighting apparatus installed on a firearm that discharges ammunition having multiple projectiles, the sighting apparatus comprising:
- a mounting structure having a firearm engaging portion attachable to a firearm;
- and
- a laser light emitting unit coupled to the mounting structure, the laser light emitting unit comprising:
- means for outputting a cone-shaped beam of laser 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;
- a cone angle adjuster operable to adjust the cone angle of the cone-shaped beam, wherein the cone-shaped beam passes through the cone angle adjuster, wherein the cone angle adjuster is movable to a plurality of cone angle adjustment settings, wherein the cone angle of the cone-shaped beam at a first of the cone angle adjustment settings is different than the cone angle of the cone-shaped beam at a second of the cone angle adjustment settings, whereby at a fixed reference distance from the sighting apparatus a diameter of the illuminated sighting reference projected by the cone-shaped beam on the target at the first cone angle adjustment settings is different than the diameter of the illuminated sighting reference projected by the cone-shaped beam on the target at the second cone angle adjustment setting;
- and
- means for correlating the cone angle adjustment settings to different multi-projectile ammunitions capable of being discharged from the firearm.
