L-C, that guy's stock looks sanded! Check out the finger groove and the safety cutout. I kinda like his chrome bayonet, magazine, and recoil pad! I wonder if anyone that got the m59/66's got sanded stocks?
I could bring my gas tube into work and analyze it with my "special" gun to see if there is any chrome or nickel remaining. There doesn't look to be any. Maybe they were just highly polished?
