With proper maintenance and care, your Mossberg® 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 gun cleaning kit.
A Always be sure that the safety button is fully rearward in the "ON" (SAFE) position (Figure 1) and that the shotgun is unloaded by visually 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 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.
