ABSTRACT:
There is disclosed a small arms sight assembly which enables a firearm such as a revolver or rifle to be employed for both nighttime and daytime use. The gun sight assembly includes a typical telescopic sight assembly of a conventional design which sight assembly includes an image intensifier module which can be selectively removed from the telescopic sight. The intensifier module or assembly when employed in conjunction with the remaining sight components enables the user to operate the weapon under low light conditions. During daytime operation the intensifier module housing section is removed. In this manner there is described a sight which enables a small weapon to be employed for daytime or nighttime use while providing increased effective weapon range when compared to conventional sight devices.
