A refinement of the World War One era MP18 SMG, the MP28.II was part of the last generation of "heavy metal" SMGs, prior to the transition to the MP38/MP40 models for the Germans. Blade front and tangent rear sight, with a ventilated receiver that doubles as a heat shield for the barrel and a magazine well marked "M.P.28.II/SYSTEM/SCHMEISSER/PATENT". The underside of the receiver bears the serial number. A manual hook safety is integrated into the receiver, with a "D" and "E" marked pushbutton selector switch built into the trigger guard. Fitted with a smooth pistol grip stock with grasping grooves on the forearm and a ribbed steel buttplate. Includes a brown leather sling and some spare parts. The deactivation was performed by installing a metal plug in the breech and grinding down the tip of the firing pin; the bolt moves freely and has an unobstructed firing pin hole, and the trigger mechanism is fully functional.
