Otis B.O.N.E. 7.62mm Carbon Cleaning Tool

The Otis B.O.N.E. Tool FG-276 brings the same compact carbon-scraping concept to 7.62mm AR-style rifle components. Its purpose-shaped edges are designed to work on the bolt, bolt carrier, and firing pin areas where baked-on fouling can be difficult to remove with patches alone. The larger 7.62mm sizing separates it from the 5.56/.223 FG-246 version.

Using a dedicated scraper can make routine bolt-carrier cleaning more efficient by giving the user surfaces shaped for the parts being cleaned. One small tool can address several carbon-prone locations without filling a pouch with multiple picks and scrapers. It works best as part of a normal maintenance routine alongside solvent, brushes, and wipes.

FG-276 is intended for shooters maintaining compatible 7.62mm AR-pattern rifles. Checking the platform and caliber before purchase is important because the smaller 5.56 tool uses different dimensions.
