The B.O.N.E. Tool was designed specifically to clean the bolt carrier assembly area. This quick-clean tool serves four purposes: scrapes carbon and fouling from the Bolt, Bolt Carrier, and Firing Pin. It includes a 8-32 threaded hole to act as a T-handle.
This model fits 5.56mm rifles. It may also fit some bolts better than others due to variance in bolts by different manufacturers.
