Otis 7.62 BONE Tool
The Otis 7.62 B.O.N.E. Tool is a dedicated carbon scraper designed to clean the bolt carrier group of AR-10 and other 7.62x51mm/.308 MSR-pattern rifles. Each working surface is profiled to match a specific area of the BCG — the bolt tail, the interior of the carrier, and the firing pin — so you can strip off baked-on carbon fast without solvents or guesswork. An 8-32 threaded port accepts a screw or rod section as a T-handle for extra leverage on the worst fouling. If you run a 7.62 AR, 6.5 Creedmoor, or .243 Win gas gun and want a faster, more thorough BCG cleaning, this is the tool to throw in your kit.

Description
Features
- Purpose-Built For 7.62 MSR/AR Platforms — Engineered specifically for the bolt carrier group of 7.62x51mm NATO/.308 AR-10 pattern rifles and compatible chamberings like 6.5 Creedmoor and .243 Winchester.
- B.O.N.E. (Bolt/Carrier/Firing Pin) Geometry — Machined surfaces match the contours of the bolt, bolt carrier interior, and firing pin to scrape away baked-on carbon and fouling in a single pass.
- Bolt Tail Carbon Scraper — Recessed cutout strips hardened carbon rings from the bolt tail where standard brushes and patches can't reach.
- Bolt Carrier Interior Scraper — Stepped profile cleans the inside diameter of the carrier, restoring proper bolt travel and lockup.
- Firing Pin Scraper — Dedicated channel removes carbon buildup from the firing pin body for reliable primer strikes.
- 8-32 Threaded T-Handle Port — Accepts a standard 8-32 screw or cleaning rod section to add leverage on stubborn fouling.
- Hardened Steel Construction — Solid steel build with a black finish stands up to repeated scraping without rounding off the working edges.
- Compact Field-Ready Size — Roughly 5 inches long and a quarter pound, it drops into a range bag or cleaning kit without taking up space.
- Made In The USA — Manufactured by Otis Technology in Lyons Falls, New York, a longtime supplier of cleaning systems to U.S. military forces.
