SureFire FM57 BeamCover for 1.0" Diameter Bezel

The FM57 attaches to any SureFire WeaponLight or flashlight with a 1.0" bezel, providing the window with protection against impact, abrasion, mud, etc. The hinged opaque lid flips open to allow normal light output, thoroughly sealing off all light when closed, providing further protection against accidental light activation during stealth operations. Locks hold opaque lid in open or closed position even under weapon recoil. Integral attachment clamp features self-locking tightening screw; 1/16" hex (Allen) wrench included.
