Latest Patents
One of her latest inventions is the Universal Bore Sight. This device is designed to be compatible with various calibers of firearms, allowing for the alignment of optical devices such as rifle scopes. The bore sight features a housing with a spring-loaded arbor that extends from one end. The arbor has a tapered face that varies in diameter, accommodating popular calibers ranging from .17 to .50 caliber. It is inserted into the end of the barrel as far as the caliber permits. As the arbor retracts into the housing against the spring force, the magnetic alignment face of the housing contacts the end of the barrel, aligning the bore sight with the centerline of the bore. A laser on the bore sight projects a beam aligned with the bore centerline, facilitating the alignment of the optical device. Additionally, a second embodiment of the bore sight does not include an arbor and is hand-centered on the barrel, fixed in place by the magnetic attraction.
