M4A1 Customized

I was going through weapons section in ArtStation and I thought why not I make my gun and with some changes in it. When I used to play PUBG PC, I always wondered why the magazine on this guns are so small. So, I made this M4 with a larger magazine and some changes in it. I made this gun when I was still getting use to Autodesk Maya and Substance. This is one my my early works.
