Abstract: A cylindrical silencer tube is fastened to the muzzle of a firearm. The interior of the tube is equipped with a series of chambers and conically shaped baffles which direct part of the discharge gases and sound waves in a different path from the main discharge and then causes them to reunite before they discharge the silencer at a point where part of the sound waves have been delayed and are hence out of phase with the principal waves and cause elimination of the noise. Specially constructed inlet and outlet chambers within the tube aid in the suppression of the sound waves and deafening of the noise. The exterior of the cylindrical silencer tube is equipped with a series of cooling fins to aid in the dissipation of heat from the silencer.
