Upgraded HISS tank canopy. This canopy will fit the 25th Anniversary HISS tank and all versions based off this mold. Please note that the 25th anniversary HISS is a new mold and as such this canopy is not compatible with the original. This canopy creates an armored look and was inspired by the HISS V.5. As of February 2012, this part is available in Transparent, Frosted and Frosted Ultra Detail materials for customers interested in creating a version of this canopy with windows that can be painted to match the color of the HISS tank.
