Lvl.50 MKb ejecting full rifle cases

After painful grinding and bot farming :D, I have unlocked the scope and beautiful select grade finish for the Maschinenkarabiner. But as I eagerly tested the weapon, I noticed that it ejected FULL 8mm Mauser rifle cases. It happens only on the three-chevron weapon. The lower upgrade-class weapons correctly eject 8mm Kurz shells. Strange.



I suppose that can be quickly fixed.
