Bore Tech Bore Brite illumination system is an innovative light source designed for convenient, hands-free examination of dark, hard-to-reach areas commonly found in firearms. The system includes two interchangeable nosecones, engineered to enhance the light output from the Streamlight Stylus LED light pen, thereby improving viewing capabilities. The white nosecone fits over the tip of the light pen, softening and focusing the light on the barrel walls. This feature aids in inspecting the interior of the barrel by clearly illuminating the bore without causing glare to the user. Consequently, the bore condition can be assessed quickly, easily and comfortably for obstructions, debris or imperfections. Additionally, a small, powerful rare earth magnet on the side of the nosecone secures the Bore Brite in place for hands-free operation when examining the bore. The black nosecone incorporates a 3mm diameter, 5 inches long, flexible fiber optic cable engineered to project intense white light into confined spaces like cartridge cases, trigger assemblies and bolt interiors Streamlight Stylus LED light pen - iPX4 water-resistant, precision-machined aluminum housing, anodized non-slip knurled grip, high-intensity solid-state LED bulb with 100000 hr lifespan, 60 hr runtime
