These forends replace the original factory forend of your shotgun and feature virtually indestructible compact LED heads with precision-molded Total Internal Reflection (TIR) lenses. These produce a tighter, farther-reaching beam than our reflector models but are still well-suited for close- to mid-range engagements. Our dedicated forends for shotguns and submachine guns are available with small but powerful LM1 compact LED head. The LM1 uses one 123A lithium battery and generates 100 lumens. Model 618LMG comes with Pressure pad, constant-on rocker and disable rocker.
