Night sight and method of making the same

Image Number 8 for United States Patent #7827727.

A night sight includes a notched bottom portion, permitting the use of a large objective lens for maximized light gathering capability while also permitting the night sight to be mounted with its center line relatively close to the center line of the barrel of the weapon with which it is used. This configuration permits the night sight to be mounted so that its center line is the same as the center line of a daytime telescopic sight used in conjunction with the night sight. The night sight includes a focusing assembly having decreased sensitivity to tilt or decenter, and a collimator mounted within a spherical bearing so that the collimator may be precisely aligned during assembly of the night sight. The night sight thereby ensures that an image viewed through the night sight appears to originate from the same angle as that with which the image entered the objective lens, and further resists a need to compensate for parallax during aiming.
