OTIS Technology B.O.N.E. Tool

The OTIS Technology B.O.N.E. Tool is a compact cleaning accessory designed to help remove carbon buildup and fouling from the bolt carrier assembly components of MSR/AR-style platforms. It supports routine maintenance by providing dedicated surfaces for scraping carbon from the bolt, bolt carrier, and firing pin.

This tool includes an 8-32 threaded hole, allowing it to function as a T-handle when paired with compatible cleaning rods. It is available in two size options—5.56 and 7.62—each compatible with multiple chamberings. The 5.56 model works with .223/5.56mm/300 Blackout/.350 Legend, and the 7.62 model works with .308/7.62/6.5 Creedmoor/.243 Winchester.

Due to variations between manufacturers, fitment may differ slightly from one bolt to another. The B.O.N.E. Tool offers a practical, portable option for users seeking efficient carbon removal during regular maintenance tasks.
