The Armytek filter has a push fit design with 40 mm internal diameter. Designed for Armytek flashlights with this length head diameter, the filter is available in red or green.
The green is suitable for hunting as it does not frighten animals as well as tactical applications as the beam cannot be seen from a side on view. The red filter is ideal for reading maps and navigating at night, in addition to signalling.
