Helli to the forum: I recently picked up a krag bayonet dated 1896. It will not fit on either of my 1898 krag rifles.the catch goes on ok it is the ferrule that is too small to go on the barrel. Was there a difference in barrel diameter between rifles? I have a 1901 dated bayonet that fits both rifles. There is no rust or Mark's on the inside of the ferrule.  Were these bayonets used on any other rifles? Maybe with a larger barrel diameter. It is smaller by quite a bit. You would have to real twist it hard to get it on the krag barrel. Any ideas?
