Well, lets start by what it doesn't have - any kind of way of mounting it to a gun. It also doesn't have any holes in the tang where the grips were riveted or screwed on. To me it looks like the blank for a bayonet, before the grove for the mount were cut etc.
I used to love being able to hit hard at 1000 yards. As I get older I find hitting a mini ram at 200 yards with the 22 oddly more satisfying.
