Saw someone shItting on the institute rifle so I wanted to clarify

The institute laser is made for robots, and most likely designed to function terribly for humans. They made it big and bulky for the purpose of "If a human captures it, they'll hate it and it won't be reverse engineered." Robots will never complain about the weapon's size or ugliness, and they'll use it effectively even if it's a glorified cinderblock.
