Safe gun handling does not stop with your gun’s mechanical “safety”
devices—it starts there. Always treat this shotgun with the respect due
a loaded, ready-to-fire firearm.
3WHENEVER YOU HANDLE A FIREARM OR HAND IT TO SOMEONE,
ALWAYS OPEN THE ACTION IMMEDIATELY. VISUALLY CHECK YOUR 
SHOTGUN’S CHAMBERS.
Make certain that they do not inadvertently
contain any ammunition. Always keep the chambers empty and the
“safety” in the “on safe” position unless shooting is imminent.
4
DO NOT TRANSPORT ANY LOADED FIREARM.
Keep all firearms
unloaded during transport whether stored in a holster, gun case,
scabbard or other container.
5
HUNTING FROM ELEVATED SURFACES SUCH AS TREE STANDS IS 
DANGEROUS.
Doing so may increase the risk of handling 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.
6
BEWARE OF BARREL OBSTRUCTIONS. 
For the safety of both your gun
and yourself. Mud, snow and an infinite variety of other objects
may inadvertently lodge in a barrel bore. It takes only one small
obstruction to cause dangerously increased pressures that may
damage your gun and cause injury to yourself and to others.
BEFORE CHECKING FOR A BARREL OBSTRUCTION, BE CERTAIN NO 
LIVE ROUNDS ARE IN THE CHAMBERS. PLACE THE “SAFETY” IN THE
“ON SAFE” POSITION.
After assuring yourself that the shotgun is 
completely empty, again, open the action and look through the 
barrels to be sure they are clear of any obstruction. If an obstruction
is seen, no matter how small it may be, clean the bore with a cleaning
rod and patch as described in “Cleaning Suggestions” on page 20.
Before the first firing, clean the bore with a cleaning rod and patch,
and wipe away any anti-rust compounds in the action/chamber areas.
3
YOU ARE RESPONSIBLE FOR 
FIREARMS SAFETYAs 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 your shotgun and any other firearm with intense
respect for its power and potential danger.PLEASE READ AND UNDERSTAND ALL OF THE CAUTIONS, PROPER 
HANDLING PROCEDURES AND INSTRUCTIONS OUTLINED IN THIS BOOKLET
BEFORE USING YOUR NEW FIREARM. 1
ALWAYS KEEP THE MUZZLE OF YOUR SHOTGUN POINTED IN A SAFE
DIRECTION
even though you are certain the shotgun 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 SHOTGUN’S MECHANICAL “SAFETY”
DEVICE.
The word “safety” describes a gun’s trigger block mechanism,
sear block mechanism, hammer block mechanism or firing pin block
mechanism. These mechanical devices are designed to place your gun
in a SAFER status. No guarantee can be made that the gun will not
fire even if the “safety” is in the “on safe” position. The Cynergy has a
thumb-operated top tang “safety” which blocks the gun’s trigger. See
“Operation of the Safety” on page 9 for instructions on operation of
this gun’s “safety. ”
LIKE ANY MECHANICAL DEVICE, A “SAFETY” CAN SOMETIMES FAIL; 
IT CAN BE JARRED OR INADVERTENTLY MANIPULATED INTO AN 
UNSAFE CONDITION. 
Mechanical “safeties” merely aid safe gun 
handling and are no excuse for pointing your shotgun’s muzzle in 
an unsafe direction.
While it is a good idea to “test” your shotgun’s mechanical “safeties”
periodically for proper function,
NEVER TEST THE “SAFETY” WHILE
YOUR SHOTGUN IS LOADED OR POINTED IN AN UNSAFE DIRECTION. 
03-220/Cynergy OM  4/14/04  4:05 PM  Page 2 
						

							7
ALWAYS UNLOAD YOUR SHOTGUN WHEN NOT IN USE.
As a safety 
precaution, it is preferable to disassemble your gun for storage.
Store your gun and ammunition separately–well beyond the reach of
children. Take all safeguards to ensure your shotgun does not become
available to untrained, inexperienced or unwelcome hands.
8
USE THE PROPER AMMUNITION.
The barrel and action of this shotgun
have been made with substantial safety margins over the pressures
developed by established American commercial loads. Nevertheless,
Browning can assume no responsibility for incidents which occur
through the use of shotshells of nonstandard dimensions which
develop pressures in excess of commercially available ammunition
which has been loaded in accordance with standards established by
Sporting Arms and Ammunition Manufacturer’s Institute (SAAMI).
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. Open the action and remove all shells from the chambers. Glance
down the barrels to make sure that a wad or other obstruction does
not remain in the barrel. Completely clear the barrel before loading
and firing again. Failure to follow these instructions can cause 
extensive damage to your gun and possible serious injury to yourself
and others.
Make sure of adequate ventilation in the area that you discharge a
firearm. Wash hands thoroughly after exposure to ammunition or
cleaning a firearm.
Lead exposure can be obtained 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.
9NEVER INSERT A SHELL OF THE INCORRECT GAUGE IN ANY SHOTGUN.The gauge of your shotgun is marked on the barrel. Store all 
shotshells of different gauges in completely separate and well-marked
containers. Never store shells of mixed gauges in a common container
or in your pockets.
EXAMINE EVERY SHELL YOU PUT IN YOUR GUN. DO NOT PUT A 20
GAUGE SHELL IN A 12 GAUGE GUN. DO NOT PUT A 28 GAUGE SHELL
IN A 20 GAUGE GUN. DO NOT PUT A .410 BORE SHELL IN A 28 GAUGE
GUN. 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 MAY RESULT IN SERIOUS INJURY TO YOU AND TO OTHERS.The most certain way to bulge or rupture a barrel is to drop 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 gun
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 correct gauge shell is then fired, the result may be a so-called
“12-20, 20-28 or 28-.410 burst” which can cause extensive damage to
your gun and possible serious injury to you and to others.
10USE SHELLS OF THE CORRECT LENGTH. 
Do not use 3 or 3
1⁄2 shells in 
a barrel with a 2
3⁄4 or 2
1⁄2 chamber, or 3
1⁄2 shells in a barrel with a 
3 chamber. Doing so can result in a build-up of dangerously high
pressures that may damage your gun and possibly cause serious
injury to yourself or others. The size of the chamber is inscribed on
the side of the barrel.
11
DO NOT SNAP THE FIRING PIN ON AN EMPTY CHAMBER — THE 
CHAMBER MAY NOT BE EMPTY! 
Treat every gun with the respect due 
a loaded gun, even though you are certain the gun is unloaded.
12
KEEP YOUR FINGER AWAY FROM THE TRIGGER WHILE UNLOADING,
LOADING OR UNTIL YOU ARE READY TO SHOOT. 
13
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.
14
ALWAYS UNLOAD YOUR SHOTGUN’S CHAMBERS BEFORE CROSSING A
FENCE, CLIMBING A TREE, JUMPING A DITCH OR NEGOTIATING OTHER
OBSTACLES.
Never place your shotgun on or against a fence, tree, car
or other similar object.
4503-220/Cynergy OM  4/14/04  4:05 PM  Page 4 
						

							15
WEAR EYE AND EAR PROTECTION WHEN SHOOTING.
Unprotected,
repeated exposure to gunfire can cause hearing damage. Wear ear
protectors (shooting ear plugs or muffs) to guard against such 
damage. Wear shooting glasses to protect your eyes from flying 
particles. 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. Also, wear eye protection when 
disassembling and cleaning your shotgun to prevent the possibility 
of springs, spring-tensioned parts, solvents or other agents from 
contacting your eyes.
16
DROPPING A LOADED GUN CAN CAUSE AN ACCIDENTAL DISCHARGEeven with the “safety” in the “on safe” position. Be extremely careful
while hunting or during any shooting activity to avoid dropping 
any firearm.
17IF YOUR GUN FAILS TO FIRE, KEEP THE MUZZLE POINTED IN A SAFE
DIRECTION. 
Hold this position for a minimum of 30 seconds.
Carefully open the action and remove the shotshell. If the primer is
indented, the 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 should be
corrected before further use.
18
BE DEFENSIVE AND ON GUARD AGAINST UNSAFE GUN HANDLING
AROUND YOU AND OTHERS.
Don’t be timid when it comes to gun
safety. If you observe other shooters violating any of these safety 
precautions, politely suggest safer handling practices.
19
BE CERTAIN YOUR SHOTGUN IS UNLOADED BEFORE CLEANING.Because so many gun accidents occur when a firearm is being
cleaned, special and extreme care should be taken to be sure your 
gun 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.20
SUPERVISE AND TEACH 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/shooting safety courses.
21
NEVER DRINK ALCOHOLIC BEVERAGES OR TAKE ANY TYPE OF DRUGS
BEFORE OR DURING SHOOTING.
Your vision and judgement could
be dangerously impaired, making your gun handling unsafe to you
or to others.
22
READ AND HEED ALL WARNINGS
in this instruction book, 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 for 
your Browning gun. Browning assumes no liability for incidents
which occur when unsafe or improper gun accessories or 
ammunition combinations are used.
23
PRACTICE PERIODIC MAINTENANCE — AVOID UNAUTHORIZED SERVICING.Your gun 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 Browning’s
service facility in Arnold, Missouri. Browning cannot assume 
any responsibility for injuries suffered or caused by unauthorized
servicing, alterations or modifications of Browning firearms.DO NOT, UNDER ANY CIRCUMSTANCES, ALTER THE TRIGGER, SAFETY
OR 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!

							when the trigger is pulled for the second shot. It will not fire both 
barrels simultaneously. Only one barrel will be fired with each pull 
of the trigger.
CAUTION: 
Once again, the Cynergy shotgun has
mechanical triggers. The recoil action of a fired shell in the first 
barrel is not necessary to set the trigger to fire the round in the 
second barrel. If you pull the trigger on the first barrel selected and
there is no round loaded or there is a misfire, then immediately
pulling the trigger again will fire the shell in the second barrel.
Highly skilled techniques of hand-fitting and polishing have been 
used to accomplish precise fitting of metal parts on this gun. These
painstaking operations are necessary to prevent looseness, even after
long use. You may consider your new gun to be slightly stiff. This 
close fitting, however, assures you of long lasting dependability.
SERIAL NUMBERThe serial number of your Cynergy is found under the top lever.
Record this number for future reference.OPERATION OF THE “SAFETY”The complete action (both barrels) is put “on safe” by sliding the
thumb safety/selector rearward (Figure 2). In the “on safe”
position an “S” appears directly in front of the safety/selector. The
above applies whether the selector is positioned for the “O” (over 
barrel) or “U” (under barrel) to fire first. To put the gun “off safe” the
safety/selector is moved forward (Figure 2A). Whenever you are not

NOMENCLATUREIn conventional gun terminology the position and movement of gun
parts are described as they occur with the gun horizontal and in 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 1A. For specific parts names related to disassembly, refer to
Figure 1B. All figures apply to the 12 gauge Cynergy shotguns.GENERAL OPERATIONThe Cynergy shotgun has two separate barrels aligned one over the
other. The trigger is a mechanical system. After one barrel has been
fired, your trigger shifts itself into position to fire the second barrel

actually firing your shotgun, always be certain that your gun is 
pointed in a safe direction. Check the safety manually and visually to
avoid any chance of accidental discharge. Always keep your safety in
the “on safe” position unless you are actually firing the shotgun.ASSEMBLY1
BEFORE USING, CLEAN ANTI-RUST COMPOUND FROM ALL METAL
PARTS,
paying close attention to the barrel interior and the breech
area. The various exposed metal parts of your new Browning 
Cynergy Shotgun are coated with a rust preventative compound 
for protection. Browning Oil is especially suited to remove this 
compound and give your new gun its first lubrication; however,
any quality gun oil may be used. A heavy oil or grease is 
recommended to lubricate the ejector cams on both sides of the 
barrels, along with the MonoLock Hinge mating surfaces on both
sides of the receiver (hinged surfaces) to prevent galling.
2 Prior to assembly, always make certain there is no shell in either
chamber. Remove the forearm from the barrels by pulling outward
on the forearm latch, slightly pivoting the front of the forearm away
from the barrels and moving the forearm forward (Figure 3).
After cleaning exposed metal areas carefully, place one or two 
drops of heavy gun oil or grease on the MonoLock Hinge surfaces,

3 To attach the barrels to the
action, grasp the stock’s pistol
grip with your right hand and
anchor the butt stock between
your right forearm and right
side. With the thumb of your
right hand, move the top lever
sideways to the extreme right.
Grasping the barrels in the left
hand, engage the receiver into
the mating MonoLock Hinge’s
circular arc on the barrel set
(Figure 5).
4 Push and rotate the receiver 
into the arc in a forward,
upward direction, engaging and
following the arc. You will see
the ejector spring begin to 
compress. Keep pushing/rotating
the receiver in until it fully

							LOADING AND FIRINGVISUALLY CHECK YOUR SAFETY TO BE CERTAIN IT IS IN THE “ON SAFE”
POSITION BEFORE LOADING.To load your Cynergy shotgun, move the top lever to the right and
open the breech. Check chambers and bores to be sure they’re clear 
of obstruction. Insert a shell in each chamber, or in the chamber 
you intend to fire, and close the action. Check to see that the barrel 
selector is set for the barrel you wish to fire first. By sliding the
safety/selector button to the right a “U” will appear signifying that 
the under barrel will fire first. If you slide the safety/selector button 
to the left an “O” will appear signifying that the over barrel will fire
first. Barrel selection can be made only when the safety/selector is in
the “on  safe” position. After firing one barrel, it is not necessary to
move the safety/selector to fire the second barrel. Simply release the
trigger to its original position and pull it a second time.
Remember, the Cynergy shotgun has mechanical triggers. If your 
first barrel fails to fire, you simply pull the trigger again to fire the 
second round.
Be certain you fully release the trigger between shots. If the trigger 
is not permitted to return to its fully forward position, the firing
mechanism will not re-engage. The subsequent pull will fail to fire 
the gun. Proper execution of this maneuver is necessary with any 
single trigger gun. Failure to release the trigger ordinarily occurs 
with overly rapid firing or heavily gloved fingers.TOP LEVERThe top lever operates the locking pins, which are very closely 
handfitted to the barrel lugs. Provision is made for the gradual 
wear of locking surfaces by allowing a slight excess of metal. This
exacting metal allowance keeps the breech of the gun tight.
Upon closing your gun, let the top lever snap into position–do not
retard its action with your thumb. If closed in this manner, the top
lever spring will return the top lever mechanism to locked position.

engages and locks into the 
barrel set (Figures 6 and 7).
5 To attach the forearm, place the
butt of the gun’s stock against
your upper leg and slide the end
of the forearm into the crescent
shaped recess of the receiver.
Mate the small round studs
inside of the forearm with the 
oval recesses on the barrel set
(Figure 8). Pivot the forearm up to the barrel set until it engages 
tightly (Figure 9). You should hear an audible “click” which signifies
that the forearm is properly attached. The forearm latch should be
locked and flush with the bottom of the forearm.CAUTION: WHEN ASSEMBLING YOUR SHOTGUN, DO NOT USE UNDUE
FORCE IN CLOSING THE ACTION.If the action and barrels are not properly aligned, undue force will
only cause them to grind together and score or mar the finely fitted
surfaces. If there appears to be interference, start over at Step 3, taking
time to line the receiver up, engage the mating surfaces and push the
receiver into the barrel set.

It is not necessary that the top lever return to a completely central
position, but it should not be hanging over the right side or edge of
the stock as you look down on it.
Many experienced shooters cultivate the habit of lightly pushing 
the top lever to the left after the gun is closed. This habit causes no 
trouble; it becomes automatic and is a quick method of assuring 
yourself that foreign matter has not interfered with the complete 
closure of the breech. Keep the polished breech surfaces clean and
lightly oiled.AUTOMATIC EJECTORSThe ejectors of your Cynergy shotgun are fully automatic and 
selective. That is, fired shells will be thrown completely out of the 
gun upon opening the action; unfired shells will be conveniently 
elevated high above chamber level so they can be easily lifted out for
unloading. NOTE: It is important to point the chamber — by slightly
canting the shotgun to the right (left for left-handed shooters) — so
shells eject clear of your body and face.HIVIZ
®SIGHTS
The Cynergy Sporting models are equipped with the HiViz
®
Pro-Comp sighting system for fast, excellent target alignment. It has 
interchangeable LitePipes for any shooting condition. Installation and
care instructions for this sight are included with the shotgun.DISASSEMBLYAfter having made certain there is no shell in either chamber and with
the action closed, anchor the gun’s buttstock against your upper leg
and lift outward on the forearm latch. Pivot the forearm away from
the barrels slightly, move it forward and it will detach.
Break the gun open in the usual manner by pushing the top lever 
to the right. Pivot the barrels downward to detach them from the
receiver. The forearm can now be reattached to the barrels for storage
by following the same instructions for fitting it to the barrel set
(Figures 8 and 9).
14
DO NOT TAKE THE GUN APART BEYOND DISMOUNTING THE BARRELS 
AND FOREARM FROM THE ACTION. 
This is a specialized, finely fitted 
mechanism; you may hopelessly mar it. More complete disassembly 
of the gun is not required for normal maintenance.
INTERCHANGEABLE CHOKE SYSTEMINVECTOR-PLUS
™SYSTEM 
All 12 gauge Cynergy shotgun barrels have been threaded to accept 
the Browning Invector-Plus
™choke system. You may confirm this by
looking on the right side of your barrel where the specifications are
inscribed, and where the choke markings are normally located. The
word INVECTOR-PLUS denotes that the barrel is threaded. The
degree of choke in the tube is indicated twice on each choke tube:
inscribed on the side of the tube, and indicated with a “notch” code 
on the top rim of the tube. All Invector-Plus choke tubes are made
with tempered steel and are fully compatible with all FACTORY
AMMUNITION (loaded in compliance with SAAMI specifications)
including magnum lead and steel shot loads and rifled slug loads.
Browning’s universal tube wrench is used to remove and install 
these tubes.
CAUTION:  INVECTOR-PLUS
™TUBES ARE FOR USE IN BROWNING 
SHOTGUNS WITH BACK-BORED BARRELS ONLY AND ARE NOT 
INTERCHANGEABLE WITH STANDARD INVECTOR
™CHOKE TUBES. 
DO NOT USE INVECTOR-PLUS TUBES IN BARRELS THREADED FOR
STANDARD INVECTOR TUBES. DO NOT USE STANDARD INVECTOR 
TUBES IN BARRELS THREADED FOR INVECTOR-PLUS TUBES. FAILURE TO
FOLLOW THESE WARNINGS MAY CAUSE DAMAGE TO YOUR GUN AND
CAUSE INJURY TO YOURSELF AND OTHERS.
DO NOT FIRE THIS SHOTGUN WITHOUT HAVING A PROPER CHOKE TUBE
INSTALLED. PERMANENT DAMAGE MAY RESULT TO THE THREADS.
DO NOT USE BROWNING INVECTOR OR INVECTOR PLUS CHOKE TUBES IN
ANY SHOTGUN BARRELS NOT SUPPLIED BY BROWNING. ALSO, DO NOT
USE ANY OTHER CHOKING DEVICE IN ANY SHOTGUN BARRELS SUPPLIED
