IR Tracer cartridges are meant for night operations, granting the combat  forces a stealth advantage. The bullet trace is completely invisible to the naked eye and only visible with the use of Night Vision Devices (NVDs).
Suitable for 5.56 x 45 mm weapons with 1:7 to 1:9 barrel twist. May also be offered linked with other trajectory-matched cartridges, such as Ball and/or SAT versions, in different configurations.
