The present invention relates to a gear cassette (1) for firearms, comprising: a trigger unit (3), the trigger unit comprising means for activating firing of the firearm, and a combustion unit (20) comprising: —a combustion chamber part (21) having an inlet end section (22) and an outlet end section (23) and an annular wall (24) arranged between the inlet end section and the outlet end section, the annular wall and the end sections comprising an inner surface (25) and an outer surface (26), at least one gas inlet (31, 32) and a fire outlet (33), and at least one spark plug (34) projecting into the combustion chamber, wherein the combustion unit further comprises a gas hose (6, 7) connected to the gas inlet (31, 32) of the combustion chamber part (21) for bringing the combustion chamber (74) in fluid communication with a gas unit comprising at least one gas container (4, 5), and wherein the trigger unit (3) is adapted to activate firing of the firearm by igniting gas in the combustion chamber.

In some examples, a charge holder for a grenade has an envelope made from one or more layers of a sheet material to define an interior volume to receive a charge having a charge volume less than or equal to the interior volume and a neck configured to connect to a flashbang grenade body, wherein a ratio of a charge volume of the interior volume to an envelope material volume is about 5.0 or greater.

Weapon simulators and components for a weapon simulator are provided. In particular, a lower receiver for a weapon simulator is provided. In preferred embodiments, the lower receiver comprises a first air pressure regulator contained within the lower receiver and a second air pressure regulator contained within the lower receiver and designed to supply a higher pressure compressed air than the first air pressure regulator. The first output of the first air pressure regulator controls the second output of the second air pressure regulator. The lower receiver is designed to have the higher pressure compressed air from the second air pressure regulator drive a simulation component.

A firing simulation scope, for installation on a rifle, includes an inertial measurement unit, a windage correction adjustment device, an electronic system, a microphone, a display and an interface for connection to a control station. The electronic system is configured for: receiving, via the connection interface, video data representing a field of view, through a simulated scope, in the virtual environment; displaying on the display the received video data; obtaining a real time audio microphone recording; comparing the audio recording with a predetermined firing-triggering signature of the rifle; and transmitting, to the control station via the connection interface, when the audio recording matches the predetermined signature, a firing triggering detection signal associated with inertial measurements supplied by the first inertial measurement unit and with a first adjustment setting supplied by the windage correction adjustment device, to enable the control station to determine a firing trajectory in the virtual environment.

Systems and methods are disclosed herein to improve efficiency and effectiveness in firearms and tactical training, at least in part by selectively generating images onto external target elements. One or more portable devices are selectively mounted with respect to selected ones of the external target elements, which may be fixed in position or mobile as the application demands. Each device includes a housing accommodating and configured for optical projection of light from an array of laser sources and diffractive optical elements. A device controller directs the projection of light from one or more of the laser sources according to a programmed target stimulus arrangement. The device controller may be individually and manually programmed or commanded in some embodiments, but alternatively a master controller may be implemented to coordinate light projections from an array of devices to provide any number of desired scenarios for neurological and/or physiological stimulation of users.
