The Otis B.O.N.E. Tool (Bolt and Bolt Carrier) is the precision-machined tool that strips carbon buildup from an AR bolt carrier in seconds rather than minutes. The tool’s machined surfaces match the BCG geometry exactly — slide the tool over the bolt, give it a few twists, and the carbon comes off in one motion.
Eliminates the brush-and-scrape routine that wears out cleaning brushes and dragged out the bolt cleaning process for AR shooters. Sized for standard 5.56/.223 BCGs with caliber-specific versions available. Same Lyons Falls, NY facility that supplies Otis cleaning kits to US military units.
Otis Technology has been making gun cleaning systems in Lyons Falls, New York since 1985. Every Otis kit is hand-assembled in their Adirondack-foothills facility, using the same Memory-Flex cable design that’s been the standard for US military firearm maintenance for decades. Made in the USA.
