Firearm with electrical power source

Abstract

A firearm includes a lower receiver storing an electrical power source and an upper receiver attached to the lower receiver. A pivot pin device provides a mechanical pivot point between the upper and lower receivers and a transfer of electrical power from the electrical power source in the lower receiver to at least one accessory rail attached to the upper receiver. The at least one accessory rail has electrical contacts that engage corresponding contacts on an electronic accessory device to supply the electrical power to the electronic accessory device.
