Abstract: A reflex sight comprises two apertures. One aperture is a direct view optical path of the target scene. The other aperture is a digital (e.g., thermal) camera or image intensifier. A beam combiner with two reflective surfaces (for example, a Bauernfeind, Penta, or other prism bonded to a wedge prism) and afocal eyepiece optics overlay the digital image or intensified image onto the direct view scene with matched magnification.

Abstract: A gun system has a two piece cannon assembly that is separated between a removable chamber instead of a traditional breech, and a projectile forcing cone. The chamber has a plug at one end that can accommodate any type of ignition system, and the other end is open and is attached to the barrel with a connection fitting. High pressure gases created by combustion of the propellant are sealed with a high-pressure gas compression seal at the interface between the chamber and the barrel. The connection fitting provides an attachment for a rear cannon bearing slide, which rides on rails attached to the main support structure, and also reacts any torque induced into the barrel from the actuation of the chamber/barrel locking collar. A turntable upon which are mounted two chamber elevating/support mechanisms and two projectile loader/rammer mechanisms is positioned around one of the main support structure legs.
