Originally manufactured in Germany in 1983, this firearm was reconfigured by S&H Arms of Oklahoma to match the "MP5K" configuration and act as a host for the included registered trigger pack. Hooded blade front and four-position drum rear sight, with a short barrel, vertical foregrip, and plastic buttcap with sling swivel. The original "shelf" on the rear of the magazine housing is solid, but has been altered to accommodate a functional "paddle" magazine release, and the left side of the receiver is marked to match the installed pack. The textured pistol grip has "S/E/F" marked selector positions.

Excellent, with 97% of the matte black finish, showing some light wear and handling marks overall.

Individually registered as a "Machine Gun Auto Sear" with the ATF prior to the 1986 registration cutoff, this trigger pack is configured for compatibility with "shelf" equipped H&K semi-automatic receivers, and registered for 9mm caliber. The pack is individually marked and numbered on the underside, with additional numbers on some of the individual components.

Shows mild wear and handling overall, and appears to be in good working order. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 478.
