Name: Machine gun  

The 7.62mm Bushmaster Chain Gun, originally developed for coaxial use and the smallest member of the Chain Gun family, is a rugged, highly-reliable, combat effective weapon readily adaptable to various machine gun roles. By design, it provides the optimum solution to combat the normal feed problems associated with most present-day gas operated small caliber machine guns, but with proven Bushmaster reliability.

Like the 25mm M242 automatic cannon, the 7.62mm Bushmaster Chain Gun ejects fired cases, including the retained gases, forward (outboard) and capitalizes on long bolt-dwell time to minimize gas buildup in all cupola or turreted installations. Toxic gas emission within the vehicle during firing has been proven to be less than 5 percent of that found with contemporary, gas-operated coaxial weapons.

For coaxial installation, the weapon is configured to permit barrel change in less than 10 seconds without downloading ammunition. Barrel jacket configuration can be varied to suit the needs of the specific installation and all jacket designs provide for the quick-change barrel feature.

The Bushmaster Chain Gun offers exceptional reliability and combat availability several orders of magnitude better than any comparable weapon of this caliber.

The Bushmaster Chain Gun fires 570 rounds per minute of NATO standard 7.62mm ammunition.
