Abstract: A battery compartment for a reflex sight is accessed via a pivoting lid that can be unlatched, opened, and closed by hand without tools and without removing the sight from its weapon. A button carried by the lid actuates a switch within the sight for changing a setting of the sight. Also disclosed is a reflex sight having mounting structures for accessories, such as an impact guard, a rain hood, or a rear iron sight for example. Positioning mechanisms for an LED or other aiming point display device of an aiming sight are also disclosed.

Abstract: A compact adjustment knob for an optical, mechanical, or electronic device includes a spindle supported on the device for rotation about an axis to control a setting of the device, and a releasable automatically locking lock mechanism supported on the spindle for rotation therewith. The lock mechanism includes at least one manually depressible button accessible on an outer surface of the adjustment knob and connected to an actuator shaft that extends inwardly through a drive hole in an outer side wall of the spindle so that a force manually applied to the button is transmitted by the actuator shaft to drive the lock mechanism and rotate the spindle. The lock mechanism may include a lock sleeve that is biased to a normally locked position and driven along the axis by the actuator shaft when the button is depressed.
