CM 300 carbine

The colloquially-termed "Confetti Maker" is a human ground firearm, primarily used by the United Rebel Front forces.

Introduction
The "Confetti Maker" is a .308-caliber machine gun. However, they are grossly inaccurate and significantly less effective than more advanced weapons. At close range, however, the Confetti Maker is highly effective. It acquired its pseudonym from its excessive ability to fill the air with rounds.

It is capable of firing normal or armor piercing rounds, such as MUTA-AP-09334 ammunition.

Appearances
The "Confetti Maker" is one of the types of guns that grew into standard use by UNSC rebel factions such as the United Rebel Front around 2531. Rebels bore Confetti Makers against SPARTAN-II Blue Team when Blue Team attacked a United Rebel Front encampment - Camp New Hope, planet Victoria, the 111 Tauri System. The users were killed by Kurt after he killed them using Antlion Anti-Personnel Mines and saved the captured Spartan II's.
