rusty nail gun 3d model

A detailed 3D game asset of a fictional underwater pneumatic tool, rust style game art. The object has a long, horizontal, elongated rectangular body silhouette similar to a classic construction nail-gun. It features a long, straight, horizontal metal pipe extending forward as a barrel. At the back, there is a fixed triangular wooden buttstock. Beneath the main horizontal body, a vertical handgrip extends downward. In front of the handgrip, there is a straight, rectangular transparent acrylic storage block of normal proportions, extending downward, clearly showing 6 solid long iron rods with pointed tips inside under a visible metal spring. The entire object is covered in deep orange rust, scrap-metal textures, and moss. Isolated on a neutral studio grey background, clean render, 3D digital art style.
