AKM modeling

While I participate as a 3D artist in a video game that will soon be released on PS4, I wanted to improve my modeling skills and a weapon was the perfect exercise, so I chose a classic, an AKM. The model is modeled in 3ds max and for texturing I used Substance Painter, I wanted it to have an old look, like if it was really used.
I followed the amazing AKM modeling tutorial from Tim Bergholz.
