Surefire 500LU LED Module for Legacy Shotgun/SMG Forends LM1-B-BK

Upgrade your shotgun or SMG's dedicated forend weapon light with SureFire's LM1-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 500-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 LM1-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.
