Hellion VHS-2 Bullpup Springfield Armory

I have been working on this prop as a practice for modeling & texturing for a long time. The lowpoly modeling was done in maya & for highpoly & police edges i used Zbrush . For uv i used maya & baked in marmoset. Texturing is done in substance painter & i learned a lot.
All the renders are done in marmoset, the poster & little bit of retouching is done in photoshop.
Triangle count of all - 38,115k (includes silencer, magazine , bullet , reddot , 8x)
