My cousin is in the USMC, and during the time he served 4 years in Afghanistan, he took photos of Kalashnikovs he found and retrieved from weapon caches. (He couldn't send the actual ak47 to me, because thats gun smuggling... xD)
He sent a few photos to me just for the heck of it, but i got the idea of creating a skin variant of the Ins ak47 with a darker toned worn wood and a discolored steel finish and a few areas of light rust.
There are Normal maps, world maps, and it works great with no graphical errors.
World map is high resolution as well.
There is a serial number on the back of the receiver now, like it should be on the Ak-47.
