Bridging the gap between the individual soldier’s closed-bolt assault rifle and the crew-served open-bolt machine gun is the FN HAMR (HeatAdaptive Modular Rifle). Historically infantry automatic weapons have been defined by their cycle of operation; firing from either a closed-bolt or open-bolt. Closed-bolt automatic rifle designs offer individual portability, greater accuracy and enhanced first-round reliability, but their fixed barrels retain heat during extended firing, quickly leading to the hazard of a chambered round overheating and cooking-off, which endangers both the operator and surrounding troops. Open-bolt designs are often crew-served weapons that offer higher rates of sustained fire along with the ability to change barrels to prevent cook-offs, but to do so at the expense of reduced portability and less accuracy. The FN HAMR is designed to operate in either the closed-bolt mode or the open-bolt mode, using a dual-mode firing mechanism that gauges the barrel temperature. Switching from one mode to the other is automatically performed by the thermal actuator located under the barrel just forward of the chamber. This allows the FN HAMR to instantly transition from closed-bolt mode to open-bolt mode and continue to operate safely even when barrel temperature has reached the cook-off point. When firing stops and the barrel cools, the thermal actuator self-resets and the FN HAMR switches back to the closed-bolt mode, all without manual intervention of the operator. Closed-bolt accuracy and open-bolt firepower in one weapon are now a reality with the FN HAMR. General Specifications: 5.56x45mm NATO. Selective fire. Short-stroke gas piston. Rotating, locking bolt.
