Battered sci-fi gun Free 3D model

Hello. I made a 3d model of the gun. I was thinking of making a drum mechanism. The design is designed so that the front part with the barrel leans down. If you start to disassemble it, you will see the holes. Of course, the mechanism is not worked out, but the meaning is preserved. I think you can definitely take this for concept art. It is also possible for the game engine if you do not have strict restrictions on polygons. I hope this will be useful to you. I don't put a high price on it because I don't think my skills are worth it.
