SureFire's 618LMG-B Forend Weaponlight is the ultimate upgrade for your Remington 870 shotgun. This light system is installed by removing the original forend and replacing it with the 618LMG-B weaponlight. The 618LMG-B produces an extremely powerful 1000 lumen beam of blinding white light from a nearly indestructible LED emitter, focused by a Total Internal Reflection (TIR) lens.

The 618LMG-B has three modes: momentary-on, constant-on, and disabled. Momentary-on is activated by pressing the pressure pad and will remain active until the pressure pad is released. Constant-on is activated by pressing the rocker-switch and will remain on until it's switched off. Disabled mode completely deactivates the 618LMG-B and allows for safe transportation. With its aggressive 1000 lumen beam and 1.25 hour battery life, the 618LMG-B is an outstanding addition to any home defense arsenal.
