Upgrade your shotgun or SMG's dedicated forend weapon light with SureFire's LM2-B-BK. This lens conversion assembly replaces the factory installed incandescent or LED reflector-type head and battery housing of SureFire 600-series and 900-series dedicated forend Weapon Lights with a far more compact head and housing unit and SureFire's proprietary TIR lens. This upgrade is powered by a single 123A battery and generates a 1000-lumen beam of intense white light. The use of a TIR lens makes the beam more concentrated and further reaching, making better for positive target identification. Additionally, the LM2-B-BK is constructed from aerospace aluminum, finished with a Mil-Spec anodized hard-coat, and is O-ring sealed for maximum protection from hard use and the elements.

Features of the LM2-B-BK:

• Fits all versions of these forend WeaponLights: 617, 618, 620, 621, 623, 328, 628, 629, 636, 917, 918, 920, 923, 936
• Virtually indestructible LED and TIR lens produce brilliant beam optimized for close- to medium range applications
• O-ring and gasket sealed for weatherproof reliability
