The majority of the rifles that found their way west during the fur trade era were made east of the Mississippi. A nicely balanced flintlock rifle can always find a home out here, a heavy Brown Bess or Charlesville, not so much.You are right, but that's true for all of Kibler's kits. The historical origins for all of Kibler's firearms can be located east of the Mississippi. About 70% of the population in the US lives east of the Mississippi. Another reason we see so few Brown Bess reproductions out here might be that the reproductions available to us are pretty poor.
I agree about any of the imported guns, regardless of the supplier.
