YOU ARE RESPONSIBLE FOR FIREARMS SAFETY
Failure to Follow any oF the Following warnings could result in serious injury or death.
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.
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.
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.
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.
2 never 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.
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.
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.
3 whenever 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.
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.
5 KeeP all FirearMs unloaded during transPort, even when stored in a holster, gun case,
scabbard or other container.
6 droPPing or jarring a loaded FirearM can cause accidental discharge.
E N

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.
8 store 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.
9 beware 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.
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.
10 be 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.
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.
13 use 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).
14 MaKe 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.
16 KeeP your Fingers away FroM the trigger while loading and unloading until shooting is
iMMinent.
17 be 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.
19 be 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.
20 be 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.
21 teach 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.
22 never 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.
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.
24 Practice 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. We assume no responsibility for injuries suffered or caused
by unauthorized servicing, alterations or modifications of Browning firearms.
25 we 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.

GENERAL
DESCRIPTION AND
OPERATION
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.
NOMENCLATURE
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.
SERIAL NUMBER
The serial number of your Maxus shotgun is found on the left side of the receiver, above the trigger guard.
Record this number in the space provided at the front of this owner’s manual for future reference.
INITIAL CLEANING
NOTICE! Please taKe note oF the Following inForMation beFore cleaning your FirearM.
CLEANING PARTS WITH SPECIAL FINISHES
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.
CLEANING
Various exposed metal parts of
your new firearm have been
coated at the factory with a
rust preventative compound.
Before assembling your
shotgun, clean the anti-rust
compound from the inside of
the barrel, receiver and the
action/chamber areas. A high-
quality lightweight gun oil is
ideal for removing this
compound, and for giving

AMMUNITION
use only shells oF the correct gauge and length. the gauge and length oF the chaMber is
inscribed on the side oF the 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 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.
Maxus 12 gauge, 3” chamber models will shoot all 12 gauge, 2¾” and 3”, 1 oz. and heavier factory lead
and steel field loads. Maxus 12 gauge, 3½” chamber models will shoot all 1 oz. and heavier factory lead

shotgun.
4 When ready to fire, move the ˝safety” into the off safe position, take aim and squeeze the trigger.
After a shell is fired, the gas system operates the bolt, ejects the fired shell and picks up a loaded shell
from the magazine and automatically chambers it. You may continue to fire the shotgun until the
magazine is empty by pulling the trigger to fire each shell. After the last shell is fired, the breech of the
shotgun remains open, with the bolt locked to the rear. This allows convenient and fast reloading.
If you are done shooting, leave the bolt locked to the rear, with the breech in the open position so that you
may visually inspect the chamber, bore, carrier and magazine to be sure they contain no shells.

until the magazine is empty. Be careful not to pinch your finger.
5 With the ˝safety” still in the on safe position, pull rearward on the bolt handle to eject the shell from
the chamber. The bolt will lock rearward when the action is cycled with an empty magazine.
6 Using your index finger, feel the opening of the magazine to make sure there are no shells that have
not been fed from the magazine and ejected. Visually inspect the chamber, feed mechanism and
magazine to assure there are no shells remaining.
UNLOADING BY CYCLING THE ACTION
1 With the ˝safety” in the on safe position, grasp the bolt handle and cycle the action until all shells are
transferred from the magazine to the chamber and then ejected. Take care to avoid damaging shells.
Avoid letting them fall to the ground.
2 When the last shell in the magazine has been cycled through the chamber and out the ejection port,
the bolt will lock rearward. The bolt will lock rearward when cycled with an empty magazine.
3 Using your index finger, feel the opening of the magazine to make sure there are no shells that have
not been fed from the magazine and ejected. Visually inspect the chamber, feed mechanism and
magazine to assure there are no shells remaining.

All Maxus shotgun barrels are threaded to accept the Invector-Plus™ choke system. Standard Invector™ and
Invector-Plus tubes are not interchangeable. Confirm the choke system of your shotgun by looking on the
right side of the barrel where the specifications are inscribed, where the choke markings are normally
located.
The constriction of each choke tube is indicated twice on the choke tube: on the side of the tube, and
indicated with a ˝notch” code on the top rim of the tube. The included universal choke tube wrench is

used to remove and install choke tubes.
Invector choke tubes are compatible with factory ammunition that has been loaded in compliance with
SAAMI specifications, including magnum lead and steel shot loads, sabots and shotgun slug loads.
Replacement and additional tubes and wrenches are available from your Browning dealer, or by
contacting the Browning Customer Service Department.
CHOKE TUBE SELECTION
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). 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 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.
CHOKE TUBE 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). Finger-twist the tube the
rest of the way out of the barrel.
CHOKE TUBE INSTALLATION
1 Place the ˝safety” in the on safe

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

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.
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.
INSTALLING A SPACER
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.
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.
4 Attach the recoil pad to the stock using the screwdriver. Turn the
screws clockwise to tighten. Do not overtighten the screws.
ADJUSTING CAST AND DROP AT COMB
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”.
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”.
INSTALLING A SHIM
1 Make sure your shotgun is completely unloaded and the ˝safety” is in the on safe position.
2 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.
3 Remove the stock insert to access the stock bolt nut (Figure 23).
4 Use a ½” socket wrench to remove the two stock bolt nuts and stock bolt washer. (Figure 24).
5 Completely remove the buttstock from the receiver, along with the existing shim, and install the shim
you have selected (Figure 25). Make certain you have the proper shim installed and in position before
reattaching the buttstock and recoil pad.
6 When you are satisfied with the fit, reattach the buttstock to the receiver with the washer and the
nuts.
7 Snug the nuts down with the socket wrench, do not overtighten.
8 Reinstall the stock insert.
9 Reinstall the recoil pad with care, so as not to scratch or mar the finish of the stock.

The versatility of your new shotgun can be extended with an extra
barrel. Maxus shotgun barrels are interchangeable within a given
gauge and chamber length. No special fitting is required. However,
some important restrictions must be observed:
• Never use a barrel with a 3½” chamber on a shotgun designed for
barrels with a 3” chamber.
• Never use a barrel with a 3” chamber on a shotgun designed for
barrels with a 3½” chamber.
• Never use any other barrel from any other manufacturer on your
shotgun. Some other brands may seem similar, but the barrels are
not interchangeable.
• Never use a barrel from any other Browning shotgun.
CLEANING AND MAINTENANCE SUGGESTIONS
NOTICE! Please taKe note oF the Following inForMation beFore
cleaning your FirearM.
CLEANING PARTS WITH SPECIAL FINISHES
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.
beFore PerForMing cleaning 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.

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 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.
1 Place the ˝safety” in the on safe position. Open the action and inspect the chamber and magazine to
make certain they do not contain any shells. Keep the muzzle pointed in a safe direction.
2 Remove the forearm and barrel as explained under ˝Disassembly”.
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.
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.
Most solvents are highly FlaMMable. wear eye Protection and Practice aPProPriate saFety
Measures when worKing with solvents to avoid serious injury.
6 After all leading and plastic residues have been removed, run a clean, dry patch through the bore.
Follow this with a final, lightly oiled patch.
7 Reassemble the shotgun and wipe all exposed metal surfaces with an oiled cloth making sure to wipe
away all finger marks where moisture could accumulate.
8 Inspect the barrel and chamber to be certain no patches have inadvertently been left in them. Remove
any that remain.
9 Lightly oil your firearm at the points described under ˝Periodic Oiling”. Regular, light oiling is
extremely important to the durability and reliable operation of your shotgun.
10 The wood surfaces can also be wiped with a quality, lightweight gun oil or they can be polished with
any quality furniture wax (but not both).
CLEANING THE GAS SYSTEM
1 Remove the gas system from the magazine tube as explained in ˝Disassembly”.
2 To simplify cleaning the gas system, separate the gas piston from the piston sleeve by pulling them
apart (Figure 26).
3 Spray the magazine tube, gas piston and piston sleeve with gun solvent and brush them thoroughly
