SureFire FM55 Red Filter for 1.0" Diameter Bezel

The FM55 attaches to any SureFire WeaponLight or flashlight with a 1.0" bezel, producing a smooth beam of red light that helps preserve night-adapted vision, provides low-signature output for stealth operations and is invisible to most wildlife. The hinged filter lid flips open to allow 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.
