It looks like Australium Sniper Rifle, but histories/IDs don't match...

I think the Australium Sniper leaving the 2nd compare was quicksold to a bot so the Burning Leadwear could be bought

Then the first compare link used those keys to buy an Australium Sniper lol

Can't say for sure, but it would likely support/fall in the range
