It works fine. I use a X300 with this on it on my CQB weapon to eliminate white light AD's. Had to throw some black athletic tape around the bezel so it would fit snug on the weapon. The lens popped out as well and I had to glue it back in. It works fine but is extremely overpriced for the quality.

The FM53 is an infrared filter for flashlights and WeaponLights with a 1.0" diameter bezel. Blocks 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.
NOTE: Infrared filters are not useful with white-light LEDs (light emitting diodes), which produce negligible infrared radiation.
Fits: Flashlights and WeaponLights with a 1.0" diameter bezel.
