M96 Swedish Mauser barrel and bayonet issue.
Hello all, I recently purchased my first M96 Swedish Mauser. By all appearances and markings, it is a 1918 Carl Gustaf build. I have just received what is supposed to be the correct bayonet for the rifle but when I tried to install it I discovered that the end of the barrel is flush with the front site. There is nothing for the ring on the bayonet to fit over. I have looked very closely at the muzzle and the crown appears to be factory. I hope that someone can shed some light on this. Thanks for any and all help.
