A Special MPi-81 for an Infantry Fighting Vehicle
This video showcases a rare variant of the Steyr MPi-81 submachine gun specifically designed for use within the Steyr/Saurer 4K 7FA infantry fighting vehicle. The description details the modifications made to the standard MPi-81 to adapt it for this application, including a longer barrel for firing ports, an optical sight similar to the Steyr AUG, removal of the front sling swivel, and the addition of a brass catching bag mount. The video highlights the scarcity of these specialized firearms and thanks the owner for access, as well as the Military History Museum in Vienna for providing a photo of the IFV.
