Are you sure? I believe Lyman is an American company based in Middletown Conn.that has Ivestarms in Italy build their guns. Warranty ,parts etc are taken care of here in the good ol USA. I have 4 lymans and would be willing to bet that they will outlast most factory made guns being produced today regardless of country of origin or length of warranty. The Great Plains Rifle is an exceptionally nice gun both in style and accuracy. Their inline ( the Mustang) is the only one I don't know much about. I never really liked the looks of it so I never got one.
Lyman over all in my opinion is one of the best black powder guns. Got my first one in 1981.
