Quick Answer
Clean the AR-10 immediately after returning from the hunting trip to prevent rust and debris buildup, and use a solvent-based cleaning solution and a soft-bristled brush to remove dirt and grime.
Pre-Cleaning Preparation
Before starting the cleaning process, ensure the firearm is unloaded and the magazine is removed. Disassemble the upper and lower receivers, and set aside any accessories such as the forward assist and gas block. This will give you clear access to all areas of the rifle.
Cleaning the Bolt Carrier Group
The bolt carrier group is one of the most critical components of the AR-10, and it requires special care when cleaning. Use a solvent-based cleaning solution, such as Hoppes No. 9 or Break-Free CLP, to dissolve any grime or debris that may have accumulated on the bolt and carrier. Use a soft-bristled brush to gently scrub away any stubborn grime, taking care not to scratch the metal. Allow the solvent to sit for a few minutes before wiping it off with a clean cloth.
Cleaning the Barrel and Chamber
The barrel and chamber of the AR-10 require a more thorough cleaning than the other components. Use a bore brush to scrub away any grime or debris that may have accumulated in the barrel, and a chamber brush to clean the chamber. Use a solvent-based cleaning solution and a clean cloth to wipe down the barrel and chamber, taking care to remove any residue. Allow the barrel and chamber to dry completely before reassembling the rifle.
