Streamlight's Thunder Ranch Urban Rifle Illumination System will enable you to navigate in low light with confidence. The Streamlight TL-3 tactical flashlight (lithium batteries included) included in this illumination system features Streamlight's patented Shock-Proof bulb technology designed to withstand even the punishing recoil of a 3 inch 12 gauge magnum slug without effecting light state or quality. Long Gun Rail Mount, also included, fits perfectly on a Picatinny Rail or standard handguard with AR-15/M-16 adapter, providing light where you need it most. Green filter and flip-up lens cover offers light without effecting night-vision or startling animals. Your TL-3 tactical flashlight can go where ever you go with the versatile carrying options of the adjustable lanyard and pocket clip. Whether you are a seasoned pro or a first-time shooter, learn something new from the Urban Rifle Low Light DVD featuring Clint Smith, Director or Training at Thunder Ranch, when you purchase the Streamlight Thunder Ranch Urban Rifle Illumination System from TacticalSupply today.
