Originally manufactured in 1993 (most likely as a SP89 pistol), this Heckler & Koch was converted by T. Dyer into a host gun in emulation of the MP5K submachine gun. An extra-short machine pistol variant of the MP5, the MP5K provides strong firepower in a compact package, and is associated with bodyguards and clandestine operators. Hooded post front and four-position open notch drum rear sights, clamp-on Midwest Industries picatinny rail, Trijicon MRO dot sight, model and date markings on top of the receiver. The "T. DYER" address has been added to the right side under the trigger housing, with the sear number added to the left. Receiver is "shelf" pattern, with a functional paddle magazine release, synthetic trigger housing with cosmetic pin and "S/E/F" markings, and a plastic endcap with a sling swivel. The bolt is marked "ID 422", and the bolt carrier has been professionally modified to engage the sear. A black nylon sling is included.

Very fine as reconfigured, with 98% plus factory quality matte black finish, showing some light handling marks. The furniture is in equal condition. The hammer releases a bit early on the "F" setting, otherwise mechanically very good.
