Quick Answer
To clean an AR-15 after deer hunting, use a soft cloth to wipe down the exterior, then field strip the rifle and soak all components in a cleaning solvent for 30 minutes to an hour. Use a cleaning brush to remove debris from the barrel and bolt carrier group, followed by a thorough rinse and drying with compressed air. Reassemble the rifle and store it in a dry place.
Pre-Cleaning Steps
Before you start cleaning your AR-15, make sure you have a well-ventilated area and all necessary cleaning supplies within reach. Remove any magazine and clear the chamber by pulling the charging handle back and releasing it. Next, use a soft cloth to wipe down the exterior of the rifle, paying particular attention to any areas with visible dirt or grime.
Cleaning the Barrel and Bolt Carrier Group
Field strip your AR-15 by removing the upper receiver, lower receiver, and any other components that can be easily removed. Soak all components in a cleaning solvent for 30 minutes to an hour. Use a cleaning brush to remove any stubborn debris from the barrel and bolt carrier group, working from the chamber end of the barrel outwards. Use a rod with a bore brush attached to clean the barrel, and a small brush to clean the bolt carrier group. Run a cleaning patch through the barrel to remove any remaining solvent and debris.
Final Reassembly and Storage
After cleaning and drying all components, reassemble your AR-15 in the reverse order that you disassembled it. Use a cleaning cloth to wipe down the exterior of the rifle, and apply a small amount of lubricant to any moving parts. Finally, store your AR-15 in a dry place, away from direct sunlight and moisture.
