Manufactured in Germany in 1981 and imported as a semi-automatic rifle, and then upgraded by Fleming Firearms of Oklahoma into a short barreled selective fire rifle. Hooded post front and four-position drum rear sights, with a birdcage flash hider on the "IP B" marked barrel, "HK 53" and "IB" marked magazine well, and Fleming address added to the left side of the frame under the trigger housing. Receiver is in "shelf" configuration, with "S/E/F" marked selector positions, right-handed switch, and properly configured trigger pack. Internally, the bolt and bolt carrier are "IB" marked, the latter welded up with a functional trip section. Fitted with a textured triangular handguard, textured pistol grip, and a two-position telescoping buttstock. Included with the lot are six extra magazines.

Very fine with 95% of the black finish, showing some casual and expected bubbling/flaking on the barrel under the handguard, scuffing around the ejection port and under the selector switch, and minor handling marks overall. Some minor scratches are present on the handguard and grip. Mechanically excellent.
