CLEANING AND LUBRICATION
With proper maintenance and care, your firearm will provide you with years of
dependable service. Your firearm should be inspected and cleaned periodically
to insure that it remains in good condition. Clean and lubricate your firearm as
soon as possible after use. This is especially important if your firearm has been
exposed to moisture. For maximum performance and continued satisfaction with
your firearm, periodic cleaning and lubrication are essential. Wear eye protection
during cleaning.
Use the instructions and equipment provided with a quality firearm cleaning kit.
All metal parts should be cleaned with firearm solvent and lightly lubricated with
firearm oil. Over-lubrication should be avoided. Use only lubricants specifically
designed for firearms. Avoid the use of abrasives which may damage the metal
finish.
If the firearm is to be stored for a long period of time it should be thoroughly
cleaned and oiled. Do not plug the barrel or store in a fabric lined case that will
absorb lubricant from the firearm.
Using a cleaning patch and cleaning rod, wet the bore and chamber with cleaning
solvent. Use a bore brush and a chamber brush to remove powder residue and
fouling from the bore and chamber. Follow with cleaning patches until the bore
and chamber are clean (Fig. 36). If the firearm is to be stored, pass a lightly
oiled patch through the bore to provide a protective coating. Wipe out the inside
surfaces of the receiver with a solvent soaked cleaning patch. Dry the inside
surfaces with clean patches. Using a cleaning patch, apply a light coat of oil to
the inside surfaces of the upper receiver.
