Definitely my Sniper Rifle. Technically, it's not all on this rifle, as I've transferred over when I've upgraded rifles and such.. but none the less, never reset or farmed, just sniped with.
First cosmetic I bought when I came back in August 2017. It went through numerous 10k kills AWPs and Aussie rifles, as well as more "normal" rifles.
i used to have much more strange items with higher stat counts but this is the one that sutck arround and i am most proud of
