Create a low-poly 3D model of an AK-47 rifle. The model should be stylized, with a minimalist design and clean geometric shapes. Ensure the polygon count does not exceed 5000. Key details such as the barrel, magazine, stock, and grip should be recognizable but simplified. Use low-poly textures or vertex coloring to enhance the style. The model should be optimized for real-time use in games or other interactive applications.
