US Patent 10088269 Firearm with integrated power source

A firearm is described that includes an integrated power source, socket, and conductor connecting the power source to the socket. By integrating these elements into a firearm, a powered accessory can be attached to the firearm without the need for a mounting rail attached to a firearm. Furthermore, powered accessories need not have their own integrated power sources, but rather can connect to the power source within the firearm. This reduces the weight and physical dimensions of both firearms and accessories.
