SureFire FM53 Infrared Filter for 1.0" Diameter Bezel

The FM53 attaches to any SureFire WeaponLight or flashlight with a 1.0" bezel, blocking visible light to produce a smooth, invisible infrared beam for use with night vision devices (NVDs) or IR-capable cameras. The hinged filter lid flips open to allow white light output, thoroughly sealing off visible light when closed. Locks hold lid in open or closed position even under weapon recoil. Integral attachment clamp features self-locking tightening screw; 1/16" hex (Allen) wrench included.
