The TWM-350 Tactical Weapon-Mounted Light uses a CREE LED rated 350 lumens working in conjunction with a high-efficiency deep parabolic reflector to create a usable beam of light rated at 215 meters. This weapon light features a unique and completely ambidextrous toggle switch on each side of the light to operate the momentary-on and constant-on lighting modes. The housing of the TWM-350 is constructed from aircraft-grade 6061-T6 aluminum with a glass-filled nylon polymer battery door and toggle switch. Includes 4 Sets of Cross-Rail Inserts (2 inserts each to fit GLOCK, 1913, TSW/99, 90two), 4 Cross-Rail Mounting Cap Head Screws, Allen Wrench, and 2 CR123 Lithium batteries.
