A viscoelastic barrel dampener is provided including a shroud having an inner surface and an outer surface. A cavity is defined by the inner surface of the shroud. A barrel is positioned within the cavity. The barrel has an outer surface. A viscoelastic dampening material is disposed within the cavity and substantially fills a volume defined by the outer surface of the barrel and the inner surface of the shroud. At least one magnet is positioned on the outer surface of the shroud to apply a magnetic field to the viscoelastic dampening material.
