The .50 Cal Machine Gun is a heavy, imposing firearm with a robust, angular design typical of Fallout's retro-futuristic aesthetic. It features a long, thick barrel with a distinctive muzzle brake, a large ammo box attached to the side, and a bipod for stability. The body is primarily matte black metal with weathered textures, showing signs of wear and battle damage, including scratches and dents. The grip and stock are wrapped in worn leather for better handling. The weapon emits a subtle metallic sheen under light, with occasional rust spots adding to its post-apocalyptic charm.
