This HK91A3 is a German-made semiautomatic rifle with the correct pre-ban markings, including the Ulm stag antler and eagle/N proofs, the IB two-letter date code for 1981, and the HK Inc., Arlington, VA importer stamp. It is a pre-1989 HK Inc. import, aligning with collectors' interest in original, German-produced examples.
The A3 configuration features a retractable metal stock with a checkered rubber buttplate and a listed 15.0-inch length of pull. It is paired with a polymer pistol grip and a slim polymer fore-end, maintaining the classic HK91 profile and handling characteristics.
The rifle uses HK's roller-delayed blowback system with a fluted chamber, and it includes a forward left charging handle with a hold-open notch. Controls are marked S/F with a two-position selector, consistent with factory semiautomatic configuration.
Barrel and sighting equipment are true to the model: a standard 17.7-inch barrel capped with a birdcage flash suppressor, and HK diopter sights consisting of a hooded front post and a rotary drum rear. The stamped steel receiver includes the HK claw-mount engagement points. Capacity is listed at 20+1.
This example includes useful accessories: an installed HK clamp-on folding bipod, three HK factory 20-round magazines, the HK91 owner's manual, and a cleaning kit. The bore condition is excellent, with sharp rifling and a mirror finish.
