Probably one of the top ten unicorn guns in the world. What was the last bid on one of these? 300k USD?
>is it a good gun?
The few examples in existence are well made, by any standard, but this was designed when sniper rifles as a concept were still taking baby steps.
It's a semi-auto, the barrel isn't free floating, and the reciever is being held together by a dozen screws. The design doesn't lend itself to accuracy, but it seems to be a solid workhorse for pounding those .300 winmags. Expect ~1MOA accuracy with the correct loads.
