The Vajra M50 Advanced Individual Weapons System (AIWS) was the evolution of the Type-220 Anti-Armor Carbine. Following the Battle of Endor after the Empire was forced from Eshan the Mikaru Corporation looked at the Type-220 and its flaws. The Model overheated after a few shots, and its magnetic rails suffered catastrophic abrasion after only a few hundred rounds. The most crippling flaw of the 220 however, was its kick, despite the shock absorber, the type-220 kicked so hard that no two consecutive shots came close.
