Thanks for the reply guys :D @FridockShir: These materials are only placeholder, they get replaced in the lowpoly. They are simple Diffuse/Gloss Shader nodes mixed, with a grunge texture in the roughness input (i rendered these in Cycles)
You always have such awesome looking normals, so envious. One thing I would change, as suggested by cR45h is the wood grain and I would also maybe add some defects in your diffuse and normals. I've never seen such a smooth brand new looking m1 carbine in my life, apart from the synthetic plastic ones.
