M4 Bushmaster XM-15 E2S

My first try at using PBR textures in one of my university projects that I was working on. Initial aim of this projects was quick applying of different tiled texture patterns to make weapon skins. As the model and substance version is fairly old my plan is to revive this project as now I see that the geometry and the textures for the gun could be improved.

(Needs new renders rather than document images)
