Tips for Effective Cleaning

  • Use Quality Solvent: Choose a solvent specifically designed for firearms.
  • Don’t Over-Lubricate: Too much lubricant can attract dirt and debris.
  • Clean Regularly: Regular cleaning prevents buildup and ensures reliable performance.
  • Inspect Components: Check for wear and tear on brushes and patches.

Maintaining Your Otis B.O.N.E. Tool

The Otis B.O.N.E. Tool is a durable system, but it requires some maintenance to ensure its longevity. After each use, clean the cable and attachments with solvent and allow them to dry completely. Store the kit in a dry, protected location. Replace brushes and patches as needed. Following these simple steps will keep your B.O.N.E. Tool in top condition for years to come.

Field Repair Capabilities of the Bone Tool AR 15

Beyond cleaning, the bone tool AR 15 can assist in limited field repairs. The included multi-tool (in some kits) can be used for tightening small screws or making minor adjustments. The cable itself can sometimes be used to dislodge minor obstructions in the bore. However, it’s crucial to understand the limitations. The B.O.N.E. Tool is not a substitute for a complete armorer’s toolkit and should not be used for complex repairs. The USDA Forest Service provides general outdoor safety guidelines, which include being prepared for equipment malfunctions.

Leave No Trace and Firearm Maintenance

As outdoor enthusiasts, we have a responsibility to minimize our impact on the environment. When cleaning your AR-15 in the field, be sure to collect all used patches, solvents, and lubricants. Dispose of them properly in accordance with local regulations. Leave No Trace principles apply to all outdoor activities, including firearm maintenance.

In conclusion, the Otis B.O.N.E. Tool is a valuable investment for any AR-15 owner.
