CLEANING AND LUBRICATION
With proper maintenance and care, your Mossberg ® firearm 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
firearm, periodic cleaning and lubrication are essential.
Follow the instructions and use the equipment provided with a quality gun
cleaning kit.
Always be sure that the safety button is fully rearward in the “ON” (SAFE)
position (Figure 1) and that the firearm is unloaded by visually and
physically checking the chamber, elevator, and magazine tube before
cleaning your firearm. Wear eye protection during cleaning to protect your
eyes from oil spatter or spring loaded components.
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 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 of the firearm.
BARREL CLEANING
Scrub the bore and chamber with solvent and follow with cleaning patches until the
barrel is clean. A final pass with a lightly oiled patch will provide a protective coating.
A stiff brass bristle brush is useful for removing stubborn deposits.
Be sure not to leave cleaning patches, excessive oil or grease in the bore as
they can create dangerous obstructions, resulting in damage to the firearm
and/or serious personal injury to you or those around you.
ACTION CLEANING
Clean all components of the action including the bolt, slide, and link (Figure 11) to
remove accumulated residue. An evaporating solvent should be used. Action parts
will remain cleaner, longer, if lubrication is used sparingly.
