The Profense® M134 is an electrically driven, (24 VDC) mechanically actuated, Gatling style machine gun with a sustained rate of fire of 3,000 rounds per minute (RPM) (+/- 10%). Optionally, the PF M134 can be equipped with a “Dual Rate” digitally controlled GCU that allows the user to select either a 1500 RPM or 3000 RPM rate of fire.

Descended from the PF M134, the all new PF 556 has been designed using the same patented technology and aerospace manufacturing processes but with the additional benefits of being a lighter weight more compact system. The PF 556 is equipped with a fully programmable digital GCU that incorporates full brushless motor control of the weapon and the ammunition booster. This unique feature allows for precise weapon and ammunition quantity management.
