I unlocked this on Sat., April 20th, 2013
The "Skunker" medal was the final onyx I needed.
I know they're blurry, but I did the best I could.
The reason you see the Gnasher Shotgun Onyx is because I purposely sat at 5999 gnasher kills, so I wouldn't miss the achievement popping while I had my console running skunker matches. I used my last gnasher kill to pop the achievement.
