Call of Duty 4 Modern Warfare
Uses Omas' G-36 skin, all his. I used it as a base for the orange transparent magazine commonly found on most G-36's using a 30-round magazine.
Here's my favorite skin for the G36c to date - it's the same shade of gray as K&K's USC and UMP carbines, and as usual, has their logo. The clear mag was changed out for a solid one (real).
This G36c has the same body color as the custom versions really available. It wouldn't be complete without H&K's logo right on the side in their shade of red.
This skin makes the G36c to have white stripes.
