You Are Responsible For Firearms Safety
Failure to follow any of the following warnings could result
in serious injury or death.
Remember, safe gun handling does not stop with your firearm’s
mechanical “safety” devices, it starts there. Always treat this firearm
with the respect due a loaded, ready-to-fire firearm.
Some firearms do not have a mechanical “safety.” Many target
firearms, lever-action firearms and pistols do not have manual
“safety” mechanisms. Therefore it is critical to read and
understand the owner’s manual for every firearm which explains
the safe operation of the firearm.
There is no excuse for careless or abusive handling of any firearm.
At all times handle this firearm and all other firearms with intense
respect for their power and potential danger.
While it is a good idea to test your firearm’s mechanical “safety”
periodically for proper function, never test the “safety” while your
firearm is loaded or pointed in an unsafe direction.
Please read and understand all of the cautions, warnings, notices,
proper handling procedures and instructions outlined in this owner’s
manual before using your new firearm.
3Whenever you handle any firearm, or hand it to someone,
always open the action immediately and visually check the
firearm’s chamber to Make certain that the firearm is
completely unloaded.
Make certain the firearm does not inadvertently contain any
ammunition. Always keep the chamber empty and the “safety”
in the on safe position unless shooting is imminent.
As a gun owner, you accept a set of demanding responsibilities. How
seriously you take these responsibilities can be the difference between
life and death.
1 ALWAYS KEEP THE MUZZLE OF YOUR firearm POINTED IN A SAFE
DIRECTION even though you are certain it is unloaded.
Never point any firearm at anything you do not intend to shoot.
Be extremely alert and aware of all persons and property within
the range of your ammunition.
2Never rely totally on your Firearm’s mechanical “safety”
device. Like any mechanical device, a “Safety” can sometimes
fail; it can be jarred or inadvertently manipulated into an
unsafe condition.
The word “safety” describes a firearm’s trigger block mechanism,
sear block mechanism, hammer block mechanism or firing pin
block mechanism. Mechanical “safeties” are designed to place your
firearm in a safer status, and no guarantee can be made that the
firearm will not fire even if the “safety” is in the on safe position.
Mechanical “safeties” merely aid safe gun handling and are no
excuse for pointing your firearm’s muzzle in an unsafe direction.
See “Operation of the Safety” on page 11 for instructions on the
operation of this firearm’s “safety.”
2
08-121-BFA_Maxus OM.indd 2-3
4 Always WEAR Ear AND Eye PROTECTION WHEN SHOOTING.
Unprotected, repeated exposure to gunfire can cause hearing
damage. Wear hearing protection (shooting ear plugs or muffs)
to guard against such damage.
Wear shooting glasses to protect your eyes from flying particles.
Allow proper distance (eye relief) between a scope and your
eye when firing a scoped rifle, shotgun or pistol. Do not use
unorthodox shooting methods that could cause the rearward travel
of the slide or bolt of a firearm to contact your eyes, face or hands.
Always keep a safe distance between the muzzle of your firearm
and any persons nearby, as muzzle blast, debris and ejecting shells
could inflict serious injury.
Always wear eye protection when disassembling and cleaning any
firearm to prevent the possibility of springs, spring-tensioned
parts, solvents or other agents from contacting your eyes.
3
6/22/09 2:59:56 PM
5Keep all firearms unloaded during transport, even
when stored in a holster, gun case, scabbard or
other container.
6DROPPING or jarring A LOADED FIREARM CAN CAUSE
ACCIDENTAL DISCHARGE.
This can occur even with the “safety” in the on safe position. Be
extremely careful while hunting or during any shooting activity
to avoid dropping any firearm.
7 hunting from elevated surfaces such as treestands
is dangerous.
Doing so may increase the risk of mishandling a firearm. The
following rules should always be observed by you and those you
hunt with. Always make certain that the stand being used is safe
and stable. Always make certain that your firearm is unloaded
when it is being taken up and down from the stand. Always make
certain that your firearm is not dropped from the stand, or
dropped while it is being taken up or down from the stand.
Remember, a loaded firearm may discharge when dropped, even
with the “safety” in the on safe position.
8Store your firearm and ammunition separately, well beyond
the reach of children.
Take prudent safeguards to ensure your firearm does not become
available to untrained, inexperienced or unwelcome hands. Store
all firearms in secure, locked cases or a gun safe. Keep your firearm
unloaded when not in use.
9BEWARE OF BARREL OBSTRUCTIONS.
Mud, snow and an infinite variety of other objects may
inadvertently lodge in a barrel bore. It only takes a small
obstruction to cause dangerously increased pressures that
can damage your firearm and cause serious injury to yourself
and others.
4
08-121-BFA_Maxus OM.indd 4-5
BEFORE CHECKING FOR A BARREL OBSTRUCTION, BE CERTAIN
YOUR FIREARM IS COMPLETELY UNLOADED, THERE IS Not a
LIVE shell IN THE CHAMBER AND THE “SAFETY” IS IN THE
ON SAFE POSITION.
After assuring yourself that the firearm is completely unloaded,
open the breech or action and look through the barrel to be sure it
is clear of obstructions. If an obstruction is seen, no matter how
small it may be, clean the bore with a cleaning rod and patch as
described on page 36 of this owner’s manual.
10Be alert to the signs of ammunition malfunction. if you
detect an off sound or light recoil when a shell is fired,
do not load another shell into the chamber.
If your firearm fails to fire, keep the muzzle pointed in a safe
direction for a minimum of 30 seconds. Carefully open the action
and remove the shell from the chamber. If the primer is indented,
the defective shell should be disposed of in a way that cannot
cause harm. If the primer is not indented, your firearm should
be examined by a qualified gunsmith and the cause of the
malfunction corrected before further use. Glance down the barrel
to make sure that no obstructions remain in the barrel. Completely
clear the barrel before loading and firing again. Failure to follow
these instructions can cause extensive damage to your firearm and
possible serious injury to yourself and others.
11 never insert a shell of the incorrect gauge into
any firearm.
The gauge of your firearm is marked on the barrel. Store all shells
of different gauges in completely separate and well-marked
containers. Never store shells of mixed gauges in a common
container or in your pockets. See page 15 for more information
on the correct ammunition for your firearm.
5
6/22/09 2:59:56 PM
12 examine every shell you put in your firearm.
We assume no responsibility for the use of unsafe or improper
firearm and ammunition combinations or damage or injury
caused by damaged ammunition. It is your responsibility
to read and heed all warnings in this owner’s manual and on
ammunition boxes. See page 15 for more information on the
correct ammunition for your firearm.
13USE ONLY SAAMI APPROVED AMMUNITION.
The barrel and action of this firearm have been made with
substantial safety margins beyond the pressures developed by
established American commercial loads. Nevertheless, we can
assume no liability for incidents which occur through the use of
shells of nonstandard dimensions or which develop pressures
in excess of commercially available ammunition which has been
loaded in accordance with standards established by the Sporting
Arms and Ammunition Manufacturers’ Institute (SAAMI).
14Make sure of adequate ventilation in the area that you
discharge a firearm. Lead exposure can occur from
discharging firearms in poorly ventilated areas, cleaning
firearms or handling ammunition.
Lead is a substance that has been known to cause birth defects,
reproductive harm and other serious injury. Wash hands
thoroughly after exposure to ammunition or after cleaning
a firearm.
15 do not snap the firing pin on an empty chamber; the
chamber may not be empty!
Treat every firearm with the respect due a loaded firearm, even
though you are certain the firearm is unloaded.
16KEEP YOUR Fingers AWAY FROM THE TRIGGER WHILE LOADING
and unloading UNTIL shooting is imminent.
6
08-121-BFA_Maxus OM.indd 6-7
17BE SURE OF YOUR TARGET AND BACKSTOP, particularly
during low light periods.
Know the range of your ammunition. Never shoot at water or
hard objects.
18 ALWAYS UNLOAD your firearm’s CHAMBER BEFORE CROSSING
A FENCE, CLIMBING A TREE, JUMPING A DITCH OR NEGOTIATING
OTHER OBSTACLES.
Never place your firearm on or against a fence, tree, car or other
similar object.
19BE DEFENSIVE AND ON GUARD AGAINST UNSAFE GUN
HANDLING AROUND YOU AND OTHERS.
Don’t be timid when it comes to firearms safety. If you observe
other shooters violating any of these safety precautions, politely
suggest safer handling practices.
20BE CERTAIN your firearm is UNLOADED BEFORE CLEANING.
Because so many firearm accidents occur when a firearm is being
cleaned, special and extreme care should be taken to be sure your
firearm is unloaded before disassembly, cleaning and reassembly.
Keep ammunition away from the cleaning location. Never test the
mechanical function of any firearm with live ammunition.
21TEACH AND SUPERVISE FIREARMS SAFETY TO ALL MEMBERS OF
YOUR FAMILY, ESPECIALLY TO CHILDREN AND NON-SHOOTERS.
Closely supervise newcomers to the shooting sports. Encourage
enrollment in hunting and shooting safety courses.
22NEVER DRINK ALCOHOLIC BEVERAGES OR TAKE ANY TYPE
OF DRUGS BEFORE OR DURING SHOOTING.
Your vision, motor skills and judgment could be dangerously
impaired, making your gun handling unsafe to you and to others.
7
6/22/09 2:59:56 PM
23 read AND HEED ALL WARNINGS in this owner’s manual, on
ammunition boxes and with all accessories that you install
on your firearm.
It is your responsibility to secure the most up-to-date information
on the safe handling procedures of your Browning firearm. We
assume no liability for incidents which occur when unsafe or
improper firearm accessories or ammunition combinations
are used.
24Practice periodic MAINTENANCE, AVOID UNAUTHORIZED SERVICING.
Your firearm is a mechanical device which will not last forever,
and as such, is subject to wear and requires periodic inspection,
adjustment and service. Browning firearms should be serviced by
a Browning Recommended Service Facility or by our Service
Facility in Arnold, Missouri. We assume no responsibility for
injuries suffered or caused by unauthorized servicing, alterations
or modifications of Browning firearms.
25WE RESERVE THE RIGHT TO REFUSE SERVICE ON FIREARMS THAT
HAVE BEEN ALTERED, ADDED TO OR SUBSTANTIALLY CHANGED.
Removal of metal from the barrel, or modifications of the firing
mechanism and/or operating parts, may lead to a refusal of service
on such firearms. We will charge you for parts and labor to return
the firearm to original specifications.
DO NOT, UNDER ANY CIRCUMSTANCES, ALTER THE TRIGGER, SAFETY
OR other PARTS OF THE FIRING MECHANISM OF THIS OR ANY
OTHER FIREARM. FAILURE TO OBEY THIS WARNING MAY RESULT IN
INJURY OR DEATH TO YOURSELF OR OTHERS.
Be careful!

G e n e r a l d e s c r i p t i o n a n d Op e r a t i o n
The Browning Maxus is a gas-operated, autoloading shotgun capable
of quickly firing up to five shells (with the three-shot adaptor
removed, using 2¾" loads), one shell at a time, with each successive
pull of the trigger. Upon firing, high-pressure gases from behind the
shot charge pass through two ports in the barrel, through the gas
bracket and into the gas system, forcing it rearward. As the gas system
moves rearward, it forces the bolt to the rear, operating the action.
As the bolt moves rearward, it cocks the hammer and ejects the fired
shell. After full rearward travel, the bolt returns forward, picks up a
new shell from the magazine and chambers it. After the last shell
has been fired, the bolt locks to the rear facilitating fast reloading.
N o m e n c l at u r e
In conventional firearm terminology the position and movement of
firearm parts are described as they occur with the firearm horizontal
and in the normal firing position: i.e., the muzzle is forward or in
front; the buttstock is rearward or to the rear; the trigger is downward
or underneath; the rib is upward or on top. For general parts
nomenclature, refer to Figure 1. For specific parts names related to
disassembly, refer to Figure 2.

Initial Cleaning
NOTICE! PLEASE TAKE NOTE OF THE FOLLOWING INFORMATION BEFORE
CLEANING YOUR FIREARM.
C l e a n i n g P a r t s w i t h Sp e c i a l F i n i s h e s
Be especially careful when cleaning firearms with camouflage,
Dura-Touch® Armor Coating and other special finishes. Always
prevent these surfaces from coming in contact with cleaning solvents,
barrel scrubbers and other strong chemicals. It is preferable to clean
these surfaces with a lightweight gun oil containing no solvents, or
with a damp cloth and mild dish soap (be sure to keep water out of
the action). When cleaning your firearm’s bore and action, protect the
external finishes from any contact with chemicals used. Also, avoid
any contact between external finishes and other strong chemicals like
those found in DEET-containing insect repellents, sunscreens, etc.
Damage to camouflage, Dura-Touch and other finishes caused by
chemicals is irreversible and not repairable.

barrel. Do not use ammunition other than what is inscribed
on the side of the barrel. Examine every shell you put in your
shotgun. failure to follow this warning could result in
serious injury or death and cause damage to your shotgun.
Use shells of the correct length. Do not use 3" or 3½" shells
in a barrel with a 2¾" chamber, or 3½" shells in a barrel with
15
6/22/09 2:59:57 PM
a 3" chamber. Doing so can result in a buildup of dangerously
high pressures. failure to follow this warning could result
in serious injury or death and cause damage to your shotgun.
do not put a 16 or 20 gauge shell in a 12 gauge shotgun. do
not put a 28 gauge shell in a 20 gauge shotgun. do not put a
.410 bore shell in a 28 gauge shotgun. never put metallic
cartridges of any kind in a shotgun. specifically, never put
centerfire rifle or pistol cartridges in a shotgun chambered
for .410 bore. failure to follow this warning could result in
serious injury or death and cause damage to your shotgun.
The most certain way to bulge or rupture a shotgun barrel is to load
a smaller gauge shell into a larger gauge chamber. The smaller gauge
shell will not fall completely through the barrel; its rim is caught by
the front of a larger gauge chamber or at the larger gauge’s choke.
Your shotgun will misfire (with the chamber appearing to be empty).
It is then possible to load the correct gauge shell behind the smaller
gauge shell. If the shotgun is then fired, the result will be a so-called
“12-16, 12-20, 20-28 or 28-.410 burst” which can cause extensive
damage to your shotgun and possible serious injury to you and others.
We can assume no responsibility for incidents which occur through
the use of shells of nonstandard dimension or those developing
pressures in excess of SAAMI (Sporting Arms and Ammunition
Manufacturers’ Institute) established standards.

C h o k e TU B E SELE C TION
To help you choose the correct choke tube for each hunting
and shooting situation, all Browning Invector choke tubes are
inscribed on the side with the patterns they produce with both
lead and steel shot. Each Invector tube also has notches in the
top rim of the tube (Figure 18, page 29). These notches are a code
to allow you to determine the choke designation while the tube is
installed. Rim notches refer specifically to lead shot. You will need to
use the charts on page 29 to cross-reference from lead to steel, and
determine the appropriate tube for your ammunition and hunting/
shooting situation.
Several choke tubes are supplied with your shotgun. The choke tubes
listed are also available as accessories. Remember, Standard Invector
and Invector-Plus tubes are not interchangeable. Invector-Plus tubes
are for Browning shotguns with back-bored barrels only. Before
removing or installing tubes, or reading the rim notch code, make
sure your shotgun is completely unloaded.
C h o k e TU B E REMOVAL
1 Place the “safety” in the on safe position. Always make sure the
shotgun is completely unloaded. Always keep the muzzle pointed
in a safe direction.
2 Use the choke tube wrench to loosen the tube, turning it
counterclockwise (Figure 19, page 30). Finger-twist the tube

Install or remove stock spacers to achieve
correct length of pull.
1 Place the “safety” in the on safe
position. Always make sure the
shotgun is completely unloaded.
Always keep the muzzle pointed
in a safe direction.
2 Before installing a tube, check
the internal choke tube threads
in the muzzle, as well as the
threads on the choke tube to be
sure they are clean. Lightly oil
the threads with a high-quality,
lightweight gun oil.
3 Using your fingers, screw the appropriate tube into the muzzle of
the barrel, tapered end first, notched end outward. When it is
finger-tight, use the choke tube wrench to firmly seat the tube.
NOTICE! The choke tube should be periodically checked to
assure that it is tight and firmly seated. Before checking,
follow all choke tube removal and installation safety
guidelines previously outlined.
Adjusting Length of PUll
The buttstock can be adjusted for length of pull by adding or
removing spacers (available separately) to the rear of the stock. Each
spacer extends length of pull ¼" and a maximum of three spacers can
be added with the screws provided to extend length of pull ¾". With
longer screws (not provided), more than three spacers can be added to
further extend length of pull.
Spacers can be ordered through your Browning dealer or by calling
our Customer Service Department at (800) 322-4626.

08-121-BFA_Maxus OM.indd 30-31
Before performing adjustment procedures, place the “safety”
in the on safe position. open the action and make certain YOUR
shotgun IS completely UNLOADED. Keep the muzzle pointed in a
safe direction. Failure to follow these warnings could result
in serious injury or death.
I n s ta l l i n g a s p a c e r
1 Use a #2 cross tip or Phillips screwdriver to remove the recoil pad
at the end of the buttstock (Figure 20). Place a small amount of
petroleum jelly on the screw access slits on the top and bottom of
the rear of the buttstock to prevent damaging the recoil pad. Insert
the screwdriver into each of the two access holes. Make certain the
tip of the screwdriver engages the head of the screw. Turn the
screw counterclockwise until the screw is completely loose from
the stock. When both screws are free, remove the recoil pad.
2 Add or subtract spacers to fit your firearm to your specifications
(Figure 21). After making an adjustment hold the shotgun to your
shoulder to determine if the new length feels comfortable.
Remember to always keep the muzzle pointed in a safe direction,
with the “safety” in the on safe position and make certain the
shotgun is completely unloaded.
31
6/22/09 2:59:58 PM
3 When you are satisfied with the
length of pull, start the screws
through the pad and spacer(s)
into the holes in the stock.

using the screwdriver. Turn the
screws clockwise to tighten. Do
not overtighten the screws.
Adjusting Cast and

Cast and drop adjustment shims. Shim 2 comes
on your shotgun and is not shown.
Before performing adjustment procedures, place the “safety”
in the on safe position. open the action and make certain YOUR
shotgun IS completely UNLOADED. Keep the muzzle pointed in a
safe direction. Failure to follow these warnings could result
in serious injury or death.
Six shims are included with your new shotgun (Figure 22). The
shims fit between the buttstock and receiver, allowing customized
adjustments to the comb and heel. Each shim is labeled/stamped for
a specific amount of adjustment. The neutral shim, No. 2, is already
installed on your shotgun.
Drop at comb is defined as the place on the comb that your cheek rests
when taking aim. If drop at comb is correct, your eye naturally falls in
line with the sight. Shims marked 1, 2 and 3 do not give any cast on or
off. The stock remains straight. They only adjust drop at comb.
These shims with their respective stamps are further clarified here:
• Shim 1 raises the comb approximately 1/16", and the heel
approximately 1/8".
• Shim 2 is neutral. This shim is already installed on the firearm.
• Shim 3 lowers the comb approximately 1/16", and the heel
approximately 1/8".
32
08-121-BFA_Maxus OM.indd 32-33
Cast is the offset of the buttstock from the longitudinal center line of
the firearm. Some right-handed shooters like the stock to angle away
(cast off) from their face, making their line of sight more directly in
line with the barrel. Angling the stock to the left for left-handed
shooters is “cast on.” Shims marked 1R1L, 2R2L, and 3R3L, will all
adjust drop at comb the same amount as shims 1, 2 and 3, and will also
adjust the cast right or left approximately 1/8". You will notice that the
two opposing edges of these spacers are different in thickness. For
right-handed shooters, install shims between the receiver and the stock
with the R facing the end of the buttstock, so its thicker side is on the
left side. This casts the stock slightly to the right, away from the face of
a right-handed shooter. If you turn the shim around so the L is facing
the end of the buttstock, and it will cast the stock to the left. These
shims with their respective stamps are further clarified below:
• Shim 1R1L raises the comb approximately 1/16", and the heel
approximately 1/8" and will adjust the cast on or cast off
approximately 1/8".
• Shim 2R2L adds the same amount of cast to the stock as shim
1R1L with neutral drop like shim 2.
• Shim 3R3L adds the same amount of cast to the stock as shims
1R1L and 2R2L, and lowers the comb approximately 1/16" and the
heel approximately 1/8".

external finishes from any contact with chemicals used. Also avoid any
contact between external finishes and other strong chemicals like
those found in DEET-containing insect repellents, sunscreens, etc.
Damage to camouflage, Dura-Touch and other finishes caused by
chemicals is irreversible and not repairable.

cleaning requires removal of the barrel from the receiver (cleaning the
barrel) and the removal of the gas system components. A complete
cleaning requires removal of the bolt and trigger group.
If a malfunction occurs, perform a thorough cleaning to see if it solves
the problem before seeking the services of a Browning Recommended
Service Center, the Browning Service Facility in Arnold, Missouri, or a
qualified gunsmith.

3 Using a shotgun cleaning rod with tip and patch large enough for
a snug fit in the bore, insert the rod and a lightly oiled patch in the
breech end of the barrel and run back and forth through the bore
several times. Remove and wipe the choke tube, threads and barrel
threads with a nylon brush and lightly oil.

Your Maxus shotgun will function better and more reliably over a
longer period of time if it is properly maintained and kept clean.
You should clean your shotgun after every day of shooting, and more
often if it becomes excessively dirty. At a minimum the barrel should
be cleaned and the action wiped clean and oiled after every day of
shooting. The gas system should require only occasional cleaning.
Normal maintenance can be accomplished with the barrel still
attached to the receiver (oiling and wiping down). More careful

Alternately, the Browning Barrel Weasel™ makes cleaning the bore
of your firearm fast and easy. Be sure to follow all instructions
when using any product to clean your firearm.
4 Inspect the bore from both ends for leading and plastic residue
that often remain in the bores from the shot cups in modern
shells. Leading and plastic residue will appear as longitudinal
streaks and are usually more predominant near the muzzle and
just forward of the chamber. A normal amount of either is
common and not serious.
5 If leading or plastic residue seems excessive you can remove it by
brushing the bore with a brass brush. Soak the brush or spray the
bore with a powder solvent first. Scrub until clean. To prevent
bristles from breaking off, push the brush fully through the barrel
each time before pulling it back through.

The metal parts of a firearm should receive a light film of oil after
the firearm has been exposed to weather or handling.
9 Lightly oil your firearm at the points described under “Periodic
Oiling” on page 40. Regular, light oiling is extremely important to
the durability and reliable operation of your shotgun.
Occasionally, a drop of lightweight gun oil may be placed inside
the receiver on the rails on which the bolt slides (Figure 3, page 11),
and on the surface of the magazine tube, where the gas piston slides.
This reduces friction for smooth operation.

Disassembly of the action involves the removal of the bolt assembly
and the trigger group. Disassembly beyond this point should only be
performed by a qualified gunsmith.
4 Perform any cleaning of the parts and receiver cavity as necessary.
We suggest cleaning the trigger group with a quality aerosol gun
solvent. Allow it to dry and then very lightly oil the moving parts.
Notice! DO NOT DISASSEMBLE THE TRIGGER GROUP BEYOND
THIS POINT.

removing the trigger group
1 Make sure the bolt is in the forward position.
1 Place the bolt in the forward position by holding the operating
handle and depressing the bolt release button.

trigger group with the holes on each side of the receiver.
Notice! NEVER ALLOW THE ACTION TO SLAM CLOSED BY PRESSING THE
Bolt release BUTTON WITHOUT THE BARREL INSTALLED. If the bolt is
released forward with the barrel removed, the operating
handle will strike the receiver and cause damage.
3 Reinsert the trigger guard pins and gently tap them into place
with a plastic or wooden mallet, again using caution not to
scratch the receiver.
2 Use a punch or similar object to push inward on the trigger guard
pins, taking care not to scratch the receiver (Figure 27, page 41).
Trigger group pins may be removed from either side of the
receiver. Push the trigger group pins through the receiver. Pull on
them from the opposite side to remove them.
3 Grasp the trigger guard and pull it up and out of the receiver
(Figure 28, page 41).

group and bolt assemblies from the receiver as explained under
“Removal of the Trigger Group” (page 40) and “Removal of the
Bolt Assembly” (page 42). Clean with a gun solvent as necessary,
using a nylon brush to loosen any caked-on grime.
Wipe the receiver cavity clean. Lightly oil the cavity and wipe it dry.
No further disassembly is required for cleaning.

barrel to the receiver as explained previously. Then wipe all exposed
metal surfaces with an oiled cloth, making sure to wipe clean all
finger marks where moisture could accumulate.

notice! Do not use excessive lubricant. Using too much
lubricant can interfere with the functioning of your shotgun.
Do not spray solvent inside the action tube.

NOTICE! Do not TAKE YOUR firearm’s ACTION APART beyond what
is explained in this owner’s manual. This is a specialized,
finely fitted mechanism; any attempt to disassemble the inner
mechanism may mar it for life. It is unnecessary, and may do
damage to the inner mechanism to disassemble it for routine
cleaning and oiling. Of course, misfortunes (such as dropping
your firearm in water) require appropriate attention, and in
such circumstances we recommend you immediately take your
firearm to a qualified gunsmith.
Models with special finisheS
As with any firearm, the only way to preserve its pristine condition and
collector appeal is to never handle or fire it, which in turn would
deprive you of much of the enjoyment that comes with owning a fine
Browning firearm.
While special finishes such as engraving and gold plating greatly
enhance the aesthetic appeal of your shotgun, please be aware that
they are no more durable, and in some cases may even be slightly less
durable than more common firearm finishes.
As you use your shotgun, you can expect special finishes to wear in
much the same manner as any other firearm finish. These marks are
the honest product of the hours spent enjoying your firearm and each
scuff and scratch will probably have a good story to go along with it.
m a i n t e n a n c e o f o i l f i n i s h s t o ck s
Keeping the oil-finished wood surface on your firearm looking its
best requires only a small amount of maintenance. When the surface
becomes spotted or dull, the affected area(s) can be treated using
rubbing alcohol on a soft, lint free cloth and allowed to dry. A small
amount of a linseed oil-based finish, such as Watco® Danish Oil Finish,
Deft® Danish Oil Finish, or Formby’s® Tung Oil Finish should then be
applied to the surface of the wood with a soft, lint free cloth according
to the manufacturer’s instructions. To treat the checkering, a small
amount of oil-based finish can be applied and then distributed evenly
using a toothbrush or other soft bristled brush.
