Atlas HBRa3

The Atlas HBRa3 is an automatic battle rifle chambered in 7.62x51mm NATO. It has the distinction of serving as the standard-issue combat rifle of the United States Marine Corps, and is popular with special forces and corporate security units that need heavier stopping-power when combatting drones and augmented humans.

The Atlas HBRa3 has an accessory rail on the top of the rifle, under the barrel, and on both sides.
