German Schmeissers MP 18 PBR Low-poly 3D model

I will have to be honest here as there are too many things I dislike: 1- Too lowpoly, you can see sharp corners everywhere, all curves are sharp 2- when you view the holes on the outer barrel you can see through the other side (one sided) 3- Internal magazine not modeled, same goes for internal chamber which makes rigging this not worth the time. 4- And by far the main reason I'm giving this negative is Charging handle where the wood actually goes up half way to the bolt, that part should only be metal. 5- Scale is wrong, it should be about 0.688 Texturing is good on the wood part but overall the imperfections is overdone, might be fine as a static model in the scene but that's about it sadly.
