Alternative Ways to Clean Your Firearm
If the firearm has interchangeable barrels, remove the barrel and clean as previously indicated. If the firearm cannot be cleaned from the breech as with the lever-action firearm, you will have to clean it from the muzzle end. You can place a patch or a thin cloth in the action so that residue does not fall into the trigger and safety assemblies.
Professional Repair By a Gunsmith
While cleaning a firearm, be sure to inspect it for loose screws or any signs of damage. If the firearm has been damaged or is not working properly, take it to a qualified gunsmith for inspection and repair if needed.
Do not attempt to make repairs or adjustments to the firearm yourself. Other than adjusting the sights and changing the choke on your firearm, you should always take the firearm to a gunsmith for more intricate work.
