I am a mechanical contractor so you are getting the legal opinions of a plumber but I think in the US all patents expire after twenty years. If I am right you could manufacture an exact copy of the 1992 Browning Citori without violating patent law - again excepting the copyrighted words "Browning" and "Citori".
When the light airplane business was almost sued out of business some rich guys proposed going into the business of manufacturing exact copies of the Cessna 172 (182?). The patent(s) had long expired.
