Maybe that statment should have read:

"Oh and best of all....It's made in the U.S.A."

If it were made in China, or Somalia or Pakistan it wouldn't have been made in Spain either.
What's better...that it's not made in Spain or that it's made in the U.S.A.?
Made in Spain isn't really so bad is it?
The Spanish maker Ardesa makes competition muzzle loaders that are as good as what is shown above if not better.
