Dude, I can get a brand-new Mercedes for as much as those things run. You're really into the rare collector items, aren't you? For German ultra-accuracy that doesn't cost as much as a house in some areas, I'd go for this.
It does under 0.5 MOA with factory ammo, less with custom. Note the Germans like to attach the bipod to the top of the rifle so the barrel hangs underneath it.
