In conjunction with the 2010 AUSA Annual Meetings and Exposition being held next week in Washington, DC, FN Herstal is pleased to introduce the new FN Heat Adaptive Modular Rifle (HAMR).

Derived from the innovative FN SCAR™ weapon system, the new FN HAMR is a revolutionary, lightweight, magazine-fed, 5.56x45mm infantry weapon that enhances the automatic rifleman’s maneuverability and displacement speed while still providing the ability to suppress or destroy both area targets and point targets in today’s fluid battle space. In addition, the visual profile and the firing signature of the FN HAMR are virtually identical to that of the standard infantry rifle, thus reducing the counter-fire threat from enemy forces.

The high-tech FN HAMR platform is a unique, highly adaptable, fully-modular selective fire weapon system that bridges the gap between an individual battle rifle and a squad automatic light machine gun in one compact package. For enhanced accuracy and greater first-round reliability, the magazine-fed FN HAMR initially fires from the closed bolt in either semi-automatic or full-automatic modes. For added safety during sustained fire situations, the FN HAMR automatically transitions into open-bolt operation in both semi-automatic and full-automatic modes before reaching the cook-off temperature of the chambered cartridge. Once the chamber temperature has dropped to a safe level, the FN HAMR automatically transitions back to closed-bolt mode. These transitions between closed-bolt and open-bolt modes are thermally regulated by the FN HAMR and occur without any manual intervention by the operator.

“We are extremely enthusiastic in presenting the revolutionary technology incorporated into the FN HAMR,” noted Mark Cherpes, Vice President of Military Operations for FNH USA. “The FN HAMR is truly a leap ahead in small arms technology that immediately provides the U.S. Military greater insight into our concepts for the development of a lightweight, multipurpose machine gun / automatic rifle using conventional ammunition. The FN HAMR will provide a springboard to further advancements in weapon designs and high capacity feeding concepts.”
