SureFire FM36 Blue Beam Filters

• The FM36 Blue Filter produces a smooth beam of blue light.
• Hunters use the blue filter to track wounded game at night because blood stands out more distinctly against foliage when viewed under blue light.
• The filter is also useful for close range, non-tactical applications - such as map reading -- as it reduces the intensity of light output.
• 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 flashlight.
• A cam-locking lever keeps the entire unit securely attached to the flashlight.
• Provides secondary protection to flashlight lens window
• Does not impair night vision
• Fits 1.25" bezels, including Z2, C2, C3, G2Z, G2, 6P, 9P
