The Auto Grenade Launcher is a heavy weapon with a bulky, industrial design, featuring a large cylindrical drum magazine mounted on top of a robust, angular frame. The body is primarily constructed from weathered metal with visible weld marks and scratches, giving it a rugged, post-apocalyptic appearance. The grip and shoulder stock are wrapped in worn leather for better handling, while the barrel is short and wide, designed to launch grenades at a rapid pace. The color scheme is muted, with shades of rusted brown and gunmetal gray, accented by faded yellow caution stripes on the drum magazine.
