IMPORTANT "SAFETY WARNINGS" - NOTE THE SYMBOL ^
THESE SAFETY WARNINGS ARE FOR YOUR PROTECTION AS WELL AS THE SAFETY OF OTHERS. DISREGARDING INFORMATION IN THIS MANUAL MAY RESULT IN SERIOUS INJURY OR DEATH.
Be certain this owner's manual is available for reference and is kept with this firearm if transferred to another party. If manual is lost or misplaced, contact Mossberg for a free replacement copy.
After performing any work on your firearm such as cleaning, adjustments, disassembly or installation of any accessory, the firearm should be re-checked for proper functioning before firing live ammunition.
Firearms are complicated mechanisms. Any modification, alteration, or improper fitting of parts may result in a dangerous malfunction, damage to the firearm and injury to the shooter and other persons. The firearm's owner is responsible for the correct reassembly and functioning of the firearm after any disassembly or replacement of parts.
If you do not understand any of the material in this manual or have any questions, contact Mossberg or a qualified gunsmith directly.
Do not attempt to load or use any firearm until you have read and understood the information contained in its owner's manual. Before handling your firearm, you should learn how it operates and how to maintain it. This includes knowing its basic parts, how the manual safety and other safety features operate, how to safely open and close the action and how to safely load and unload ammunition from the firearm. Improper use and handling is dangerous and could cause serious injury or death to you or those around you. All users of the firearm must become thoroughly familiar with the instructions in this manual.

Safety and safe firearms handling is everyone's responsibility.
As the owner of a firearm, you must undertake the full-time responsibility of safe firearms handling for your own safety and the safety of those around you:
• Keep all firearms and ammunition out of the reach of children.
• Store your firearms and ammunition separately.
• Never store a loaded firearm.
• Never leave a loaded firearm unattended.
• Never transport a loaded firearm in a vehicle.
• Unload your firearm when you have stopped shooting and when you have to climb a tree, fence, cross a slippery surface or have to transport it in a vehicle.
• Do not load your firearm before you are in a place where it is safe to shoot and keep your finger off the trigger until you are on target and have decided to fire.
• Never shoot at water, rocks or any hard surface. Shots may glance off such surfaces and cause injuries.
• Do not use alcohol or drugs before or while handling firearms.
• Do not touch trigger while the safety button is being engaged or disengaged.
Always point the muzzle of your firearm in a safe direction, regardless of whether the firearm is loaded or unloaded.
Always treat every firearm as if it were loaded. Give your firearm to someone with the action open (bolt fully rearward) and safety fully rearward in the "ON" (SAFE) position after you verify the firearm is unloaded. Insist on the same procedure when receiving a firearm from someone else. Learn the location of all the safety features of your firearm and how they operate.
Wear eye and ear protection when shooting. Shooting without proper ear protection can cause hearing damage. The use of eye protection during any type of shooting is important to protect your eyesight.
Due to the heavy recoil of a shotgun, maintain an adequate distance between the rear of the scope (if equipped) and your face at all times. Be certain the scope installation does not interfere with access to, or the proper functioning of the safety button.
WE SPECIFICALLY DISCLAIM ANY RESPONSIBILITY FOR DAMAGE OR INJURY WHATSOEVER OCCURRING IN CONNECTION WITH, OR AS A RESULT OF, THE USE OF FAULTY, OR NON-SAAMI STANDARD, OR "REMANUFACTURED" OR HAND-LOADED (RELOADED) AMMUNITION. ADDITIONALLY, WE DISCLAIM ANY RESPONSIBILITY FOR DAMAGE OR INJURY WHICH RESULTS FROM ANY MODIFICATIONS OR CHANGES THAT ARE NOT A PART OF THE FIREARM AS DELIvERED FROM THE FACTORY.
Learn to clean your firearm thoroughly and make certain no oil, grease or other materials are blocking the barrel. Obstructions of any kind can cause damage to the firearm and may result in serious personal injury to the shooter and/or others nearby.
Practice proper firearm maintenance and safety. Make sure all exposed metal surfaces are coated with a thin film of oil, especially after exposure to damp weather. (See proper section of this manual for cleaning instructions.) Do not plug barrel or store in fabric-lined case which will absorb lubricants from the firearms. Before using after storage, follow complete instructions stated in this manual for refamiliarization with the firearm. A thorough inspection should be performed before going into the field. Have your firearm periodically checked by a qualified gunsmith.
