Manufactured in Germany in 1979 (date code "HK") and imported as a semi-automatic rifle, this HK91 was upgraded by Hard Times Armory with a shelf-compatible trigger pack for selective fire operation. Hooded blade front and 4-position drum rear sights, with a bird cage flash hider, textured triangular handguard, ribbed right handed pistol grip, and two-position telescoping buttstock. The receiver bears the standard markings on the magazine well, with the Hard Times address on the right rear side near the pin holes, and the trigger housing has "0/1/A" markings on the left side (right side still has the original "0/1" markings), with a restrictor stud milled down and a right handed selector switch. With shipping box. Provenance: The Al Walker Collection

Very fine as upgraded to full auto, with 95% plus matte gray finish, showing mild handling marks overall, most prominent at the mounting points for a scope base (not included). The furniture is in equal condition. Mechanically excellent.
