Well, here it is. I don't know a whole lot about it except that it is a custom built rifle with a Mauser action, three round box magazine, and a 20 inch barrel. I bought it from the original owner who had it made about 50 years ago. I forget what he said he paid for it.So far, I have only run about 40 rounds through the rifle. It was a cold windy day, but I still managed to shoot a couple of groups with bullet holes touching (truth be told, I also managed to shoot a couple of groups bigger than my hand at 100 yards, but I prefer to blame those on my cold fingers).
