If you really want to dazzle your fellow weapon aficionados, break this thing out on them.  The Mkb 42 Assault Rifle (Non Firing Replica) is the prototype predecessor of the dreaded German MP44 Sturmgewehr.  In fact, you could say that this replica assault rifle is the direct grand-daddy of all modern assault rifles today.  During World War II, the Germans realized that infantry warfare had dramatically changed since the days of World War I.  Because of the nature of tank warfare, blitzkrieg, aviation, and artillery, warfare was far more fluid.  For the infantryman, most combat no longer took place at several hundred yards between entrenched lines, but at relatively close ranges within a hundred yards or less, between patches of cover and ground.  In such situations, suppressive fire was more important than accurate fire because it would keep the enemy from shooting back when the rest of the squad moved into position to strike the killing blow.  To that end, the old Mauser k98 bolt action rifle was not as good for close infantry combat as the MP40 SMG.  But the problem with that SMG was that it fired pistol ammunition, and what infantry want is something like a full rifle round that can give them the range they need when they want it.  The result was the Mkb 42.  Hitler did not approve of the weapon, so, at great risk to their lives, the general staff had these weapons secretly deployed to their troops on the front lines, and the rest is history.  Having this prototype, the grand-daddy of assault rifles, is a must to have with any collection of firearms and swords as it is part of history, and quite a handsome weapon on its own.
