![Otis - .223 / 5.56 B.O.N.E. Tool](https://velak.ee/323-medium_default/otis-556-bone-tool.jpg)
The B.O.N.E.® Tool was specifically designed to clean carbon and fouling from the bolt carrier assembly area of MSR / AR style rifles. This quick-clean tool scrapes fouling from the bolt, bolt carrier and firing pin. Also includes an 8-32 threaded hole to act as a T-handle.
Note: While this tool fits many bolts flawlessly, it may fit some bolts better than others due to variance in bolts by different manufacturers.
