GtA4 Rifle lowpoly real time model from "Titanfall 2" Game. It's great concept done by "Ryan Lastimosa". Model has around 20K polygons with 4K PBR textures.
Just be noted: This is NOT the original model from the game. It's just a fan art for my portfolio.It's based on original concept art directly from Ryan's Artstation page with some small modification mostly on decals and logos on the texture.
