Abstract: A rotatably adjustable mount for removably mounting an NV monocular onto a weapon is disclosed. The mount has a base and a rotatable side fixture. The base is configured to clip onto a rail on the weapon. The side fixture has a battery section, an electronics section and a lever section. The battery section supports a battery. The electronics section is electrically connected to the battery section and includes power-management electronics. The lever section locks and unlocks the NV goggle to the side fixture. The side fixture has a slot configured to receive an NV mounting fixture of the NV monocular and establish electrical contact between the electronics section and the NV monocular. The side fixture is rotatable between an in-line position and an out-of-line position of a downstream day sight supported by the weapon. A night-vision weapon sight that employs the mount is also disclosed.
