The Mossberg barrel heat shield kit (brand part no. 95066) dresses up any plain-barreled Mossberg 500, 590, or Maverick 88 pump shotgun in 12 gauge, adding a factory-style heat shield over the barrel. Finished with a durable Parkerized coating, it’s a straightforward cosmetic and functional upgrade that gives a plain barrel the classic heat-shield look without any gunsmithing. Fitment matters here, so check your specific model configuration before ordering, since several Mossberg variants aren’t compatible with this shield.
