Streamlight Inc. offers the second product of its collaboration with Clint Smith and Thunder Ranch - the Urban Rifle Illumination System. Based around a new shockproof version of the popular TL-3 flashlight and a newly developed aluminum rail mount that allows quick light attachment/detachment from the firearm, the system also includes an exclusive Clint Smith instructional DVD. Designed to withstand even the punishing recoil of a three-inch 12-gauge magnum shotgun round, the shockproof TL-3 and rail mount can be securely mounted to any firearm with a Picatinny-style rail. It allows the user to attach or detach the light from the weapon in seconds, allowing the TL-3 to function as a handheld or secured gun-mounted light.
