Surefire Blue Filter for 1.0" Diameter Bezel

The FM56 attaches to any SureFire WeaponLight or flashlight with a 1.0" bezel, producing a smooth beam of blue light that helps preserve night-adapted vision, provides low-signature output for stealth operations, and makes blood and hydraulic fluid appear deep black making it easier to see. The hinged filter lid flips open for white light output, thoroughly sealing off white light when closed. Locks hold diffuser lid in open or closed position even under weapon recoil. Integral attachment clamp features self-locking tightening screw; 1/16" hex (Allen) wrench included.
