HG 1/144 ARX-014 Silver Bullet Gundam

A mobile suit used by the Earth Federation Forces to test the Quasi-Psycommu system, the Silver Bullet is a modified AMX-014 Döven Wolf created by Anaheim Electronics based on captured units. Although its armament is trimmed down due to its purpose, it gained higher output compared to the original Döven Wolf and is more than capable of participating in actual combat. The removal of the abdominal mega particle cannons also lightens the suit. Some Silver Bullets have a Gundam head for testing the Quasi-Psycommu weapons, while others have a GM head for system analysis of the enhanced measurement sensors.
