A sight assembly for a firearm includes an optical sight configured for mounting to a firearm. The optical sight includes a sight body retaining a lens and has a point-of-aim indicator visible on the lens. A light source on the sight body is configured to communicate a firearm status to a user, such as whether a round is chambered in a chamber of the firearm. In one example, the sight assembly can be mounted to a handgun or atop a rifle. In some embodiments, the optical sight is configured as a reflex sight.

Firearm stock of the type which comprise an electronic control unit in said stock and comprising a receptacle with at least one opening in the stock comb and which is configured to receive a display device. It also comprises a battery configured to be connected to the display device and a control unit configured to receive data from the electronic control unit and send it to the display device. When the display device is installed it is housed in the receptacle and the user has visual access to it by the opening of the comb so that he has access to all the firearm information in his own line of sight when he is aiming. Furthermore, the stock is equally valid for left and right-handed people.

A weapon system for a firearm having a barrel includes a powered accessory rail interface having an upper accessory rail and a lower accessory rail. A first accessory device is removably attachable to the upper accessory rail and is configured to receive electrical power and data signals over the powered accessory rail interface. A second accessory device is removably attachable to the lower accessory rail, the second accessory device configured to receive electrical power and data signals over the powered accessory rail interface. A power supply is electrically coupled to the powered accessory rail interface.

Provided is a replacement pistol barrel for reliable operation when suppressed and that will universally fit multiple versions of a handgun model.

A machine gun (e.g., a minigun) is provided with a modular delinker. The front of the delinker (i.e., nose) can be removed from the main body of the delinker without tools. The paddle wheel in the main body includes a front paddle wheel and a rear paddle wheel. The front paddle wheel is removable from the main body with the nose, and the rear paddle wheel remains within the main body on a driven shaft of the delinker when the nose is removed from the main body. Thus, some components of the delinker are accessible and serviceable without tools, and the nose and front paddle wheel may be swapped out without tools out to alter a compatible ammunition cartridge type of the delinker. A jam can be cleared and damaged front and/or rear paddle wheels can be replaced in the field to return a gun to service.

A machine gun (e.g., a minigun) is provided with a delinker including a loaded round indicator. The loaded round indictor is configured to rest flush with an outer surface of a rear door of the delinker when the rear door is closed and an ammunition cartridge is not fully loaded into the delinker. The loaded round indictor is further configured to extend outwardly from the outer surface of the rear door when the rear door is closed and an ammunition cartridge is fully loaded into the delinker.

A machine gun (e.g., a minigun) has a delinker including cylindrical or round pushrods inserted in complementary slots in a carrier. The generally cylindrical pushrod and corresponding slots in the carrier require less machining steps than prior rectangular, T shaped or H shaped pushrods and complementary carrier slots making them faster and less expensive to produce and replace. The cylindrical pushrods apply force evenly to heads of ammunition cartridges received in the delinker as they push rounds forward within the delinker such that the rounds are not forced outward from a longitudinal axis of the delinker by the pushrod as the pushrod. A front face of the pushrod has a recess corresponding to a primer of the ammunition cartridge pushed forward by the pushrod within the delinker such that the pushrods do not contact the primer of the ammunition cartridge.

The present invention relates to a cartridge-in-chamber detection system for weapons wherein the state of the cartridge in the chamber is independent in order to provide a reliable indication of the presence or absence of the cartridge in the chamber of the weapon, wherein the system comprises means to, through a supply voltage, determine the variation of the electrical capacity between the two possible states of the system, when there is no cartridge in the chamber and when there is a cartridge in the chamber, making use of at least one electrode, without the cartridge intervening in the system.
