Be certain this owner’s manual is available for reference and is kept with
this firearm if transferred to another party. If this 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/or those around you.
The firearm’s owner must accept full responsibility for the correct
reassembly and functioning of the firearm after any disassembly or
replacement of parts.

ATTIIOONN IINN TTHHIISS MMAANNUUAALL

If you do not understand any of the material in this manual or have any
questions, contact Mossberg or a qualified gunsmith.

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.

PHONE [phone]

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 surfaces. Bullets
may glance off such surfaces and cause injuries.

• Do not use alcohol or drugs before or while handling firearms.

• Do not touch the 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 and the safety button pushed 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 vision.

When using a firearm with mounted optics, maintain an adequate distance
between the rear of the scope 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.

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 being exposed to
damp weather. (See proper section of this manual for cleaning instructions.)
Do not plug the barrel or store in a fabric-lined case which will absorb
lubricants from the firearm. Before using after storage, follow complete
instructions stated in this manual for refamiliarization with the firearm. A
thorough inspection and function test should be performed before going into
the field. Have your firearm periodically checked by a qualified gunsmith.

When shipped from the factory the rifle has a protective coat of oil on its metal

parts. Before using the rifle, visually and physically inspect the inside of the barrel
to be sure it is free of any excess oil, grease or any obstructions. Obstructions of
any kind can cause damage to the firearm and may result in serious personal
injury to the shooter and/or others nearby.

The 464™ Rimfire Lever Action is designed to operate ONLY with the caliber inscribed

on the barrel.

*The chamber is the rear most part of the barrel. It can be seen when the bolt is in
the “open” position.

MMEECCHHAANNIICCAALL SSAAFFEETTYY FFEEAATTUURREESS
The safety button is located on the top rear portion of the receiver (Fig. 2) and must be

manually moved to the desired position by the shooter.

Remember, a firearm’s manual safety is a mechanical device which can never
replace safe firearm handling practices.

The manual safety, when

engaged, prevents the hammer
from striking the firing pin.

When the safety is in the “ON”
(SAFE) position, and the trigger
is pulled fully to its rearward
position, the hammer will
partially fall (shown in fig. 2), but
will not strike the firing pin.
When the safety is in the
“OFF” (FIRE) position, and the
trigger is pulled fully to its
rearward position, the hammer
will fall through its full range of
motion and strike the firing pin.

The button will now cover the red
dot. The red dot is a training aid used only to show the direction of the “ON”
(SAFE) position and should not be used as an indicator that the safety is “ON” or
“OFF.” Moving the safety button forward toward the muzzle of the rifle will put
the safety in the “OFF” (FIRE) position.

Never rely on any mechanical mechanism or safety device to prevent the
dangers of careless handling or pointing a firearm in an unsafe direction.

TTRRIIGGGGEERR SSTTOOPP
The 464™ Rimfire Lever Action is fitted with a trigger stop (Fig. 1).

The trigger stop is a mechanical means of ensuring that the bolt is fully
closed before discharging the rifle.

IItt iiss nnoott aa ssaaffeettyy

, and should not be

relied upon to prevent accidental discharge of the rifle.

The trigger stop is actuated by the finger lever and helps prevent discharge of
the firearm when the bolt is not fully closed. When the lever is closed but not held
tight to the stock, the trigger stop blocks the trigger motion, preventing the
trigger from moving fully to its rearward position. Pulling the finger lever tight to
the stock releases the trigger stop and allows the trigger to travel fully to its
rearward position. If the safety button is in the “OFF” (FIRE) position and the
trigger is pulled to its full rearward position, the hammer will strike the firing pin
and fire the rifle if a round is in the chamber.

With the action open, check the chamber and feed throat to be sure the rifle is
unloaded. To check the feed throat, look down through the ejection port. If no
rounds are present in the magazine or feed throat the orange magazine follower
will be visible projecting into the feed throat (Fig. 3)

WHEN THE ORANGE COLORED MAGAZINE
FOLLOWER IS PRESENT IN THE FEED THROAT,
IT INDICATES THAT THE MAGAZINE AND FEED
