Behind the scenes
The "GP" in the weapon's name likely stands for "general purpose," referring to the general-purpose machine gun weapon classification used by many military services.

According to Josh Sawyer the GP Machine Gun was initially going to be based upon the M60 and chambered in .308 however it was deemed unnecessary and functionally merged with the Light Machine Gun.
