In the 1980's real Sterling made 9mm Mk.4 type semi-auto carbines (called a Mk.6) were imported in small numbers. The Sterling Mk.6 were made for export and for use by police and other groups who weren't allowed use, or didn't want to use, fully automatic SMG's. About 1600 of these were made and a few came into the U.S. before the 1989 import ban.
