A Full-Body Inverse Kinematic (FBIK) module for use in tracking a user in a virtual reality (VR) environment. The FBIK module has an enclosure containing a power source, a plurality of active tags with lights for use by a motion tracking system to track the user, and a controller that flashes the lights in distinct patters to identify the user of the FBIK module.

When a semi-automatic weapon is live fired, it's firing pin is reset, and it is ready to be fired again. The shooter's hands remain in the firing position, and just the trigger finger and trigger are employed. With dry fire practice, the shooter must manually rack the slide to reset the firing pin, allowing the trigger to return to its unfired position each time a shot is simulated. This invention provides, realistic muscle memory training by duplicating the action of the trigger in normal live fire, the feel and the sound of the release of the firing pin, and the resetting of the trigger for additional trigger activation. The invention further provides components that allow use with other electronic training devices such as lasers, video simulators, and virtual reality.

Provided is a multi-use laser rangefinder usable in either of hand-held and weapon-mounted modes. It includes a compact laser rangefinder (LRF) removably mountable to a weapon system and an optical aiming unit separate from a weapon system optical sighting device. The compact optical aiming unit has a point of aim viewable therethrough and is removably attachable to the rangefinder. The LRF has a point of aim adjustable to a point of aim of the weapon system when mounted and to the point of aim of the optical aiming unit when LRF is demounted and the optical aiming unit is attached to the LRF.

Sighting devices and cartridges for a firearm comprising an internal sighting and aiming system which incorporates and leverages electromagnetic radiation as the means for aiming the firearm. The sighting and aiming system must first be placed in the chamber of a firearm to be functional. It is activated and deactivated by the angle at which the firearm is held.
