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.

Abstract: An embodiment presents a rifle including an upper receiver, a barrel assembly connected to the upper receiver and a forend with an integrated barrel nut. The integrated barrel nut is connected to the barrel assembly such that the forend is directly connected to and aligned with the upper receiver. Another embodiment provides a method for assembling a firearm. The method includes inserting a barrel assembly into an upper receiver. The method also includes threading a forend with an integrated barrel nut over the outer surface of the barrel assembly. The method also includes checking an alignment between the upper receiver and the forend.
