The latest iteration of 120mm automatic cannons employed from the onset of the war, MMP-78 brought with it many improvements over previous model in all metrics. An underslung grenade launcher compliment its increasingly-obsolete kinetic firepower, and the weapon can be modded into assault rifle configuration by attaching longer barrel & new fire control system. Using special munition the MMP-78 effective range can be increased to such a degree that even aircrafts are threatened. Another major change is the redesign of many ergonomic aspect to allow pilot to easily adapt in operating a mobile suit weapon (read : the designer took many AR-15 elements).
Glue are required to attach the foregrip mount to the receiver. Other parts don't require glue but it's still recomended to apply on non-interchangeable parts or if you find the tolerance too loose.
