Otis B.O.N.E.® Tool (5.56MM)

The B.O.N.E.® Tool was designed specifically to clean carbon and fouling from the bolt carrier assembly area of 5.56MM 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 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.
