SureFire FM43 Infrared Filter for flashlights with 1.36" diameter bezel cancels out the non-infrared portion of the light spectrum to produce a smooth beam of infrared light for use with night vision devices and infrared-capable video cameras. For military or law enforcement infrared applications, SureFire also recommends SureFire M1 Illuminator Flashlight, as its dedicated infrared design may be more appropriate for mission critical tasking. Applying thumb pressure to the locking tab releases the cover; a spring mechanism keeps the open cover out of the way by holding it flat against the Gun Mounted Flashlights. A cam-locking lever of Sure Fire IR Filter FM-43 for Weaponlights and Flashlights w/ 1.36" keeps the entire unit securely attached to the Sure-Fire flashlight.![]()
