CLEANING AND LUBRICATION
With proper maintenance and care, your Mossberg International ™ shotgun will
provide you with years of dependable service. Your firearm should be inspected
and cleaned periodically to ensure that it remains in good condition. Clean 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 shotgun, periodic cleaning and lubrication are essential.
Follow the instructions and equipment provided with a quality shotgun cleaning kit.
Always be sure that the safety button is fully to the right in the “ON”
(SAFE) position (See Figure 1a) and that the shotgun is unloaded by visual-
ly and physically checking the chamber, elevator, and magazine tube before
cleaning your shotgun. Wear eye protection during cleaning.
Normal use requires only that the mechanisms be free of excessive shooting
residue. Very little lubrication other than a light oiling of internal and external
surfaces to prevent rust is needed.
To ensure optimum performance, Mossberg International ™ recommends thorough
cleaning of your firearm after every 200 rounds. However, unusually dusty, dirty, or
harsh weather conditions, or use of ammunition which leaves significant powder
residue may require more frequent cleaning.
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, as this may result in corrosion to the
unprotected metal surfaces.
Over-lubrication should be avoided during below freezing conditions. Many
lubricants thicken in low temperatures which could affect the operation of the
firearm. Exposure to unfavorable weather or moisture from condensation requires
additional care to prevent corrosion to the firearm.
BARREL CLEANING
Remove the gas piston from the gas cylinder portion of the barrel. Scrub the bore of
the barrel, chamber and gas cylinder bore with solvent and follow with cleaning
patches until barrel and gas cylinder bore are clean. Place a few drops of light oil in
the gas cylinder bore (See Figure 17). A final pass with a lightly oiled patch in the bore
of the barrel, and chamber will provide a protective coating. A stiff brass bristle brush
is useful for removing stubborn deposits.
Be sure not to leave cleaning patches or excessive oil or grease in the bore
of the barrel as this can create dangerous obstructions, resulting in damage
to the firearm and/or serious personal injury to you or those around you.
