SureFire FM46 Blue Filter for 1.36" Diameter Flashlight Bezel

The SureFire FM46 Blue Filter is a flip-up blue filter that is dedicated to flashlights with a 1.36" bezel. The smooth prefocused blue beam of light from your SureFire flashlight can be used to track wounded game at night. Bloodstains stand out more distinctly against foliage when viewed under blue light. This blue filter produces a light beam with a reduced output level and intensity that is also suitable for non-tactical operations, such as low-light map reading, or accompanying Fido on a nocturnal stroll around the block.

Thumb pressure on the locking tab releases the cover and a spring mechanism keeps the open cover flat against the flashlight's housing. A locking lever keeps the entire unit securely attached to the flashlight's bezel.
