I recently aquired an old mauser rifle and have no clue as to where it came from. It has no factory stamp or crest as to country of origin, all of the serial numbers match on the barrel, receiver and bolt. The receiver is stamped with 7.62 and the person I bought it off of said he was shooting .308 out of it. The original wood stock is missing and a comercial sporting stock was put on. I have removed the barrel and receiver to see if their was any markings underneath and have found none. It is a very short rifle only a little over 28" long from crown to rear of the receiver and the rear sight is adjustable 300-2000 meters. There is an oval shaped hole on the left side of the reciver on the front ring that I can see the bolt through. It also has a butterfly safety on the rear of the bolt.
