High-tech shooting company TrackingPoint has introduced a new addition to their lineup, the M400XHDR. This new model is chambered in .300 BLK, comes complete with their tracking/target system and is enabled with second-generation night vision. The M400XHDR offers a 400-yard lock range and is compatible with three different ammunition profiles. TrackingPoint's Precision Target and Precision Mover calculate the ballistic and firing solutions for the shooter, delivering unequal accuracy on both stationary and moving targets. An Auto-Acquire mode snaps the reticle to the predetermined center of mass of a tagged target, while the Suppressive Fire mode calculates and holds real-time ballistic solutions, coupled with a live trigger to quickly engage multiple targets. Yes, these features work just as well in darkness as they do in daylight.
