Compatible with most rail-equipped long guns, the Nightstick® LGL-150 Compact Long Gun Light Kit features a lightweight, 6061-T6 anodized aluminum housing for lasting durability and shockproof performance. A super-bright LED delivers an impressive 450-lumen max output, while a precision-engineered, high-efficiency deep parabolic reflector maximizes the beam range out to 220 meters. This tactical light comes equipped with a standard tail cap switch and reversible thumbscrew Picatinny mount for simple installation and ambidextrous operation. Plus, the included 45° offset mount allows you to mount the light at the perfect angle to clear iron sights and other mounted equipment, without needing another rail section. Both the tail cap switch as well as the included 6″ remote pressure switch feature momentary or constant-on modes for added versatility. The kit also includes an RPS Picatinny rail mount and Nightstick-exclusive wire management rail clamp to prevent cable snags. Operates on one CR123 battery (included).
