This work presents a recently-patented small arms concept demonstrator that substantially reduces the recoil force transmitted to the user during operation. In live-fire tests, this invention produced recoil forces that were approximately 84% to 91% less than those produced by the M240 machine gun. To achieve such recoil force reduction, this invention includes design features to reduce the propellant gas contribution to recoil force and cancel the moving internal component contribution to recoil force.
