The Real Avid Carbon Boss Multitool is not just a tool, it's a real partner for any shooter. Imagine holding 16 tools in one compact package. 12 precision scraper surfaces specifically designed to remove fouling from all 4 major parts of the bolt and what's cool is that they don't leave scratches. Interchangeable nylon/phosphor bronze brush for detailed cleaning and 360-degree phosphor bronze brush. Built-in cotter pin extraction tool and puncher. All tools are accessible with one hand. There is a protective ballistic nylon case with carrying strap. Take it to the range, in the field or keep it on your workbench - it will always be handy and in one piece. Carbon Boss is suitable for a variety of firearms, especially AR platforms. It will handle fouling on the bolt, bolt carrier, gas key and other hard-to-reach areas.
