Abstract:
1. An apparatus, comprising: a body that attaches to a barrel of a firearm; a chamber, disposed in the body, that receives combustion gases from the barrel during a firing sequence of the firearm; sensors, mounted on the body, that capture a measurement of an initial line-of-sight to a target prior to the firing sequence and that measure deviation from the initial line-of-sight after capture of the measurement of the initial line-of-sight and during the firing sequence; ports, in communication with the chamber, wherein the ports are controllable to vary discharge of the combustion gases from the chamber; and a feedback control unit that receives the measurement of the initial line-of-sight and the deviation from the sensors and controls the ports to vary discharge of the combustion gases from the chamber during the firing sequence to generate forces on the barrel to drive the deviation to a minimum.
