Frequently Asked Questions
Which rifles and calibers is the Otis FG-276 Bone Tool compatible with?
The FG-276 is specifically designed for 7.62mm firearms, making it an excellent fit for platforms such as the AR-10, SR-25, M14/M1A, SCAR 17S, and other rifles chambered in 7.62x51mm NATO or .308 Winchester. Always verify your bolt and carrier dimensions before use to ensure a proper fit.
How does the Bone Tool differ from a standard cleaning brush?
Unlike traditional bore brushes or patch loops, the Bone Tool features a rigid, contoured scraping design that physically removes baked-on carbon deposits from the bolt face, bolt carrier interior, and around the firing pin — areas that brushes often fail to clean effectively. The 8-32 threaded hole also allows it to be used as a T-handle with compatible Otis system components, adding versatility to your cleaning routine.
Does the Otis FG-276 work with other Otis cleaning system products?
Yes. The 8-32 threaded hole built into the FG-276 is compatible with standard Otis cleaning system rods and handles, allowing you to integrate the Bone Tool seamlessly into your existing Otis kit. This makes it a natural upgrade for anyone already using the Otis Breech-to-Muzzle cleaning system.
