Are double barrel shotguns made by Fabrique Nationae D'arms de guerre Herstal Brownings and are they fine guns?
Fabrique Nationale is the Belgian manufacturer that used to make
firearms for Browning. (And others) I can't tell you about more the
modern era, but the older guns are excellent. They're as good as
you can get. I have a Browning 30-06 Mauser action made in 1974 by
FN, and I have an identical rifle with FN's own markings. I have a
Browning 9 mm High Power made in Belgium. Yes, they are fine
guns!
