A small lightweight weapon system for integration into an unmanned aerial vehicle comprises a weapon operating group which utilizes blowback operation to fire a full-powered centerfire rifle ammunition. An operating rod of the weapon operating group has an axis of translation offset from the longitudinal axis of the barrel thereby creating a moment couple on the system. A motor assembly controls the operation of the weapon operating group. Through a gear train, actuation of the motor assembly lifts a sear against a return torsion spring, which holds the operating group back when not firing. The gear train comprises a one way flywheel disconnect to increase the torque of the direct current motor and overcome the force of the torsion spring. Intelligent motor commutation and burst control are achieved through an encoder and software package.
