There must have been a time when this bolt-action rifle was a status symbol, but now it looks like it's spent some time lying in a swamp. You can still see traces of its former glory, and the thing still works, so in the life of a denizen of Rust island, it'll do just fine.

This is a distressed, rusted and muddied-up version of another skin I made. In this condition it seems more fitting for the Rust aesthetic. Maybe it really did lie on the ground for years and now your character has fixed it up well enough to shoot with. Perhaps it was dropped during whatever horrific events happened on the island long ago. Either way, it's yours now.
