Abstract
Abstract A method of aligning the boresight of a weapon in which the method comprises mounting an aiming light on a boresight mechanism that is attached to the weapon. A canister, which has the same diameter and general shape of a cartridge that the weapon fires and has a light emitting source and beam width narrowing projecting lens therein, is inserted in the breech of the weapon to provide a narrow beam boresight light along the true boresight of the weapon. Battery leads are connected to the light emitting source with the ground lead secured to an end cap of the canister and the hot lead connected to the light emitting source. The battery is located in the aiming light housing. The operator aligns the aiming light with the boresight of the weapon appropriately adjusting the aiming light beam with respect to the boresight light beam, and observing the position of the reflected lights from a target through a viewing scope. The canister may be pulled out of the breech by pulling on the battery leads.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
156 words
A method of aligning the boresight of a weapon, the steps comprising: inserting a canister into the breech of said weapon, said canister containing a light emitting source for providing a boresight light beam along the boresight of said weapon; mounting an aiming light on said weapon, said aiming light containing a light emitting source for providing an aiming light beam in a general parallel relationship with said boresigHt light beam; providing an aiming light aligning means wherein said aligning means appropriately positions said aiming light beam with respect to the said boresight light beam when reflected from a target at a median firing distance; providing a viewing scope that is head worn by an operator for observing the relative positions of said aiming light beam and said boresight light beam; and removing said canister from the breech of said weapon leaving said aiming light mounted on said weapon for providing boresight alignment of said weapon.
Claim 2
Independent Claim
156 words
A method of aligning the boresight of a weapon, the steps comprising: inserting a canister into the breech of said weapon, said canister containing a light emitting source for providing a boresight light beam along the boresight of said weapon; mounting an aiming light on said weapon, said aiming light containing a light emitting source for providing an aiming light beam in a general parallel relationship with said boresigHt light beam; providing an aiming light aligning means wherein said aligning means appropriately positions said aiming light beam with respect to the said boresight light beam when reflected from a target at a median firing distance; providing a viewing scope that is head worn by an operator for observing the relative positions of said aiming light beam and said boresight light beam; and removing said canister from the breech of said weapon leaving said aiming light mounted on said weapon for providing boresight alignment of said weapon.
Claim 3
Dependent Claim
25 words
A method as set forth in claim 1 wherein said canister has the same diameter and general shape as a cartridge fired in said weapon.
Claim 4
Dependent Claim
49 words
A method as set forth in claim 2 wherein said aiming light comprises a battery and an electronic pulser that produces output pulses for pulsing said light emitting source and a projecting lens for narrowing the beam width of said aiming light beam emitted from said light emitting source.
Claim 5
Dependent Claim
18 words
A method as set forth in claim 3 wherein said light emitting source is a light emitting diode.
Claim 6
Dependent Claim
20 words
A method as set forth in claim 4 wherein said light emitting diode is a gallium aluminum arsenide laser diode.
Claim 7
Dependent Claim
56 words
A method as set forth in claim 5 wherein said light emitting source of said canister is a light emitting diode and said canister further comprises a battery lead connected between said light emitting source and said battery within said aiming light and a projecting lens that narrows the beam width of said boresight light beam.
Claim 8
Dependent Claim
20 words
A method as set forth in claim 6 wherein said light emitting diode is a gallium aluminum arsenide laser diode.
Claim 9
Dependent Claim
33 words
A method as set forth in claim 7 wherein said canister further comprises an electronic pulser circuit connected between said battery lead and said gallium aluminum arsenide laser diode for pulsing said diode.
Claim 10
Dependent Claim
53 words
A method as set forth in claim 8 wherein said aiming light aligning means comprises an aiming light adapter connected to a weapons adapter, said aiming light adapter further comprising a vertical boresight adjusting means and a horizontal boresight adjusting means thereon for aligning said aiming light beam with said boresight light beam.
Claim 11
Dependent Claim
80 words
A method as set forth in claim 9 wherein said vertical and horizontal boresight adjusting means comprises a vertical boresight adjusting knob with a screw threaded stem for moving the aiming light in the vertical direction and a vertical locking screw for securing said vertical boresight adjusting knob and a horizontal boresight adjusting knob with a screw threaded stem for moving the aiming light in the horizontal direction and a horizontal locking screw for securing said horizontal boresight adjusting knob.
