FCS-MR800

40mm fire control system

The Rheinmetall FCS-MR800 fire control system is designed for 40mm LV (Low Velocity) and MV (Medium Velocity) grenade launchers. It can be mounted (e.g. with Picatinny Rail MIL-STD-1913/STANAG4694) on the grenade launcher: Single, Underslung or Multiple Grenade Launcher. The integrated ballistic computer stores the ballistics of 32 different ammunition types and calculates a ballistically corrected target point. With its precise range finding (built-in LRF) and accurately calculated elevation angle, the FCS-MR800 increases the (first) hit probability. It is completed by the electronically focusable IR illuminator and the two built-in aiming lasers (infrared and visible). The integrated motor for automatic elevation adjustment as well as the included IR-Air Burst Ammunition Programmer allows a significant combat value increase in target area.

For eye protection, the FCS-MR800 uses Rheinmetall's patented concept of color-coded trigger cables / dongles for laser and laser light modules.

"Train as you fight" - the free choice of power-defining trigger cables / dongles enables realistic training with mission-relevant equipment. The laser power is - depending on your choice - either reduced (training) or released to the maximum (combat).

Custom colors available, e.g. blue for training, black and grey for combat.
