Abstract
A viscoelastic barrel dampener operable to increase the accuracy of a weapon having a shroud, the shroud defining a shroud wall and a chamber within the shroud wall, a barrel, the barrel disposed within the chamber of the shroud and defining a barrel wall having an outer surface, and a viscoelastic dampening material, the viscoelastic dampening material disposed within and substantially filling a volume defined by the outer surface of the barrel and the shroud wall, wherein the barrel further includes one or more contour features adapted to disrupt the axial propagation of acoustic energy along the barrel wall. In at least one embodiment, the one or more contour features may include a plurality of parallel barrel walls, radial grooves, or steps formed in the outer surface.
