Last weekend I obtained a Johnson rifle for the first time. I am very happy with it, but had to think long and hard about buying it due to one problem. The barrel muzzle is threaded. I looked around on line and found a 2012 discussion about another rifle with threaded muzzle, but no one had a concrete idea about why or when the threading was done. It appears that there is solder or braze metal residue on the face of the sight base. Any thoughts on this forum?
Also, my serial number is 6343 with no letter prefix. Any chance I could get some information on it?
Thanks, Vern
