Low-poly 3D model of the Stylized Tactical Submachine Gun doesn't contain any n-gons and has optimal topology. This model contains two texture sets, so the archive with textures contains two folders:

Holographic sight screen Textures (512X512): base color map, metalness map, normal map (OpenGL), roughness map, emissive map.

Stylized Tactical Submachine Gun Textures (2048X2048): base color map, metalness map, normal map (OpenGL), and roughness map.
