TYPE OF AMMUNITION TO BE USED
It is suggested that high quality commercially manufactured ammunition be
used in this firearm.  Some factory ammunition works better than others and
you should stick with the brand you find works well in your shotgun.  Avoid
military surplus or hot loaded ammo.  
The use of reloaded, high pressure or
hand loaded ammunition will void the warranty.
N O T I C E
SHOTGUNS ARE CLASSIFIED AS FIREARMS OR DANGEROUS WEAPONS
and are sold by European American Armory Corporation with the specific un-
derstanding that we are not responsible in any manner what- so-ever for their
safe handling or resale under local laws and regulations.
European American Armory shall not be responsible in any manner whatso-
ever for malfunctioning of the firearm, for physical injury or for property dam-
age resulting in whole or in part from (1) intentional or negligent discharge, (2)
improper or careless handling, (3) unauthorized modifications and/or alter-
ation to the internal/safety mechanisms, (4) defective, improper, high pres-
sure, hand-loaded, or reloaded ammunition, (5) corrosion and/or lack of proper
maintenance (6) neglect, or (7) other influences beyond our direct and imme-
diate control.  This limitation applies regardless of whether liability is asserted
on the basis of contract, negligence or strict liability (including any failure to
warn).  Under no circumstance shall European American Armory Corporation
be liable for incidental or consequential damages, such as loss of use of prop-
erty, commercial loss and loss of earnings or profits.
SAFETY PROCEDURES
1.  We recommend that you get competent firearms instruction in safe han-
dling before using this firearm.  Please ask your dealer. All guns are extremely
dangerous if carelessly handled or used.  Remember that the 
firearm user is
the primary “safety” and to depend on any mechanical devices is to be only
half safe.
2.  This firearm will fire if a cartridge is in the chamber and the trigger is pulled
and the safety is disengaged.
3.  DO NOT LOAD THIS SHOTGUN UNTIL YOU UNDERSTAND HOW THIS
SHOTGUN OPERATES.  KEEP this shotgun unloaded at all times except when
ready to fire and you are sure of your target.
4.  ALWAYS carry this shotgun in a case or original box unloaded.
5.  NEVER point this shotgun at anything that is not your intended target even
if this shotgun is unloaded.  When loading, cleaning, unloading or handling,
always be sure the muzzle is pointed in a safe direction and always keep your
finger off the trigger.
6.  NEVER assume any gun is unloaded.  Before handling, check to make sure
the chamber is empty.  See unloading Instructions and then unload any am- 
						

							2
munition.  Make sure you know that this or any firearm is fully unloaded before
displaying or handling it.  When handling any firearm, keep your fingers away
from the trigger at all times until you intend to fire.
7.  WARNING: The actual firearm does not contain any lead; however, it does
fire ammunition containing lead or lead compounds known to the State of
California to cause cancer, birth defects, reproductive toxicity, and other seri-
ous physical injury.  Those who discharge a firearm, stand near someone who
discharges a firearm or cleans firearms are hereby warned of the dangers
presented by lead and lead compounds and should take protective health
measures.  Avoid exposure to lead while handling and wash your hands after
contact.  Proper air ventilation is absolutely necessary when shooting indoors.
A M M U N I T I O N   W A R N I N G
Old, Hot-loaded and/or re-loaded ammunition may be dangerous.  Because
of the poor or nonexistent quality control standards among some companies
or people who make reloaded ammunition and the dangers of overloads and
under loads (squib loads) which may occur, we recommend that only good
quality new factory ammunition be fired in our firearms.  [If you prepare your
own hand loads, do NOT exceed recommended pressures in line with those
generated by standard factory loads as manufactured by Remington, Win-
chester, Federal, PMC or other reputable companies.]  Old ammunition may
not fire with sufficient force to expel the projectile from the barrel.
READING THESE SAFETY RULES WILL SAVE YOUR
LIFE OR  THE LIFE OF SOMEONE ELSE
Get instructions from a competent firearms instructor before using this or any
firearm.  Learn from a professional how to handle, load, unload, operate, fire
and care for your gun.
NEVER PLAY with your firearm.  It is not a toy and can be a very dangerous
weapon that can cause serious personal injury or death.
Always keep the gun pointed in a safe direction.  Treat every gun as if it is
loaded...all the time.  NEVER point any firearm (loaded or unloaded) at any
person or anything you do not intend to shoot.  Always keep your gun un-
loaded until ready to use and make sure that it is unloaded before cleaning.
Keep your finger OFF the trigger until you are actually aiming at the target and
ready to shoot.  Learn to rest your finger outside of the trigger guard.
Never rely on a gun’s “safety” to protect you from unsafe gun handling.  A
safety is only a mechanical device, not a substitute for common sense and
gun safety procedures.
Never leave a gun unattended or where it could fall and fire.
Store guns and ammunition separately beyond the reach of children. Make
sure that they are properly secured so untrained individuals and children will
be denied access to your guns and ammo. 
						

							3
Test your gun’s operation and safeties only at a shooting range while the fire-
arm is pointed in a safe direction.
Know your target and what is beyond.  Ask yourself what your bullet will hit if it
misses the target or passes through the intended target.  Remember, a fired
projectile can travel over a mile (including a ricochet) and is capable of going
through walls.
Guns and alcohol or drugs do not mix.  Don’t take any alcoholic beverages
and/or drugs before or during shooting activities.
Never pull a gun toward you by the muzzle.  Don’t climb a tree, cross a ditch or
fence with a loaded gun.
Always empty guns before entering a house, car, truck, boat, RV, camp or any
building.
When receiving a gun, always open the bolt and check to make sure the cham-
ber is unloaded.
NEVER accept anyone’s word that a gun is “unloaded” or “empty”.  You should
immediately open the action and check to make sure it is unloaded.
Be careful with 
ALL ammunition.  Even “blank” cartridges are deadly at close
range due to the muzzle blast.  Make sure your ammunition is in new and in
good clean condition.  Do NOT oil or grease ammo as this may damage the
cartridge primer.  Do NOT tamper with or alter the standard factory ammunition.
Keep firearms unloaded when not actually in use.  Load the gun only when on
the range preparing to fire and unload it before leaving the range.
Never put your hand over the muzzle of a gun.
ALWAYS WEAR protective shooting glasses and hearing protection when us-
ing firearms.
Spectators should be at least 10 feet behind and away from the shooter while
the shooter is loading, shooting and unloading.  Spectators should wear pro-
tection for hearing and sight loss and they should avoid distracting those shoot-
ing their firearms.
Never drop your gun.  If you do drop it, unload it and check it for proper
function before using it again.
Do NOT alter or modify your gun.  Don’t try to change your gun’s trigger pull,
because it may affect sear engagement and thereby cause accidental firing.
Do NOT remove any internal safety or safety device on the firearm.  Safety
mechanisms are designed to protect you from injury or death.
Do maintain and keep your gun clean.  Keep in a dry place away from other
metals and water.  If your gun shows sign of corrosion or improper operation,
have it serviced by a competent gunsmith.
Keep the muzzle pointed in a safe direction when loading and unloading your
gun.  Never point the muzzle at anyone. 
						

							4
Never shoot at hard flat surfaces or water....bullets ricochet.
If a gun fails to fire when the trigger is pulled, keep it pointed down range at the
target for 60 seconds.  Sometimes slow primer ignition will cause a “hang fire”
and the cartridge will go off after a short pause.  If it still fails to fire, keep
muzzle pointed in safe direction and avoid exposure to the breech, as you
attempt to unload your firearm.
Never let water, snow, mud or other material enter the barrel. Always be sure
the barrel is free of any obstruction.
Since many ammunition identifications sound similar, be sure that you use
only the correct ammunition for your gun.  Do NOT use the wrong size or
wrong strength ammunition in your firearm.
Repeated and prolonged exposure to gunfire may cause toxic levels of lead in
your body.  High levels of lead in the blood may result cancer, impotency, birth
defects and other serious physical injury.  When shooting indoors, make sure
there is proper fresh air ventilation.
Teach children: 1. NOT to touch guns, bullets, cartridges, shells, flares or any
explosive device and 2. If they discovery such a dangerous item or weapon,
they must immediately report its location to their parents, school teacher and police.
Remember a firearm has the capability of taking your life or the life of someone
else.  Be careful with your firearm -- an accident is almost always the result of
not following basic safety rules.
HOME SAFETY IS PROBABLY YOUR BIGGEST CONCERN.  We suggest a
gun lock such as Master Gun Locks.  They work on most firearms and are
available in gun shops and sporting goods departments.  For more informa-
tion write: Master Gun Locks; Master Lock Company, P.O. Box 10367, Milwau-
kee. WI 53210.  You have invested this much in your new firearm, now invest a
little more in your family’s safety.
USED FIREARMS - If you got your European American Armory firearm as a
used gun, BEFORE USING IT you should unload it and check all its functions
to be sure it works correctly. Firearms are some times altered to work incor-
rectly, or parts may be removed, lost or replaced with incorrect parts. First,
unload it and check it yourself and then take it to a good gunsmith who knows
European American Armory firearms, and have him examine it.
WRITE US concerning any items or circumstances which you don’t under-
stand and which might relate to your safety and the operation of your firearm.
W A R N I N G
BEFORE LOADING or firing a shotgun, examine the bore and the firing cham-
ber to be certain they are clean and free of any obstruction.  Even a heavy coat
of oil, grease, snow or water may result in damage to the firearm and injury to
the shooter and/or persons near the firearm.  A misfire or unusual sound upon
firing is a signal to cease firing and to examine the chamber and bore.  If there is any
obstruction, clear the obstruction and clean the bore and chamber before firing.

FIRING WARNING
When shooting, full eye and ear protection is mandatory at all times.  Shooters
and spectators must wear shooting glasses and sound suppressor to prevent
eye injury and hearing loss.  Vision loss and hearing impairment can occur
with only one moment of non-protection.
W A R N I N G
Any bore obstruction, even if it is only partly blocked, may cause the gun to
blow up if it is fired, or may cause damage to the gun such as a bulged barrel.
To avoid injury or death to the shooter or bystanders, check the barrel before
shooting or if a shot does not sound normal.
W A R N I N G
Always keep the muzzle pointed in a safe direction!  Never attempt to load or
unload any firearm inside a vehicle, building or other confined space (except a
properly constructed shooting range).  Enclosed areas frequently offer no com-
pletely safe direction in which to point the firearm.  If an accidental discharge
occurs, there is great risk of injury or property damage.  Before loading, al-
ways clean all, grease and oil from the bore and chamber, and check to be
certain that no obstruction is in the barrel.  Any foreign matter in the barrel
could result in a bulged or burst barrel or other damage to the firearm and
could cause serious injury to the shooter or to others.
W A R N I N G
If there is any reason to suspect that a bullet or projectile is obstructing the
barrel, immediately unload the firearm (See Unloading Instructions) and check
the chamber and the bore.  A shot or slug may be lodged some distance down
the barrel where it can not easily be seen.  Check the bore by using a cleaning
rod to pass through the barrel.  If a blockage is in the bore, DO 
NOT ATTEMPT
TO SHOOT IT OUT WITH ANOTHER CARTRIDGE, OR BLOW IT OUT WITH A
BLANK CARTRIDGE OR A CARTRIDGE FROM WHICH THE BULLET HAS BEEN
REMOVED.  SUCH TECHNIQUE(S) CAN GENERATE EXCESSIVE PRESSURE,
DAMAGE THE FIREARM AND CAUSE SERIOUS PERSONAL INJURY.  If the
blockage can be removed with a cleaning rod, clean any unburned powder
grains from the bore, chambers & mechanism before resuming shooting.  If
the blockage can not be dislodged by tapping it with a cleaning rod, take the
firearm to a gunsmith.
WARNING (Mechanical Malfunctions)
STOP SHOOTING IMMEDIATELY AND UNLOAD YOUR FIREARM if your fire-
arm develops: a mechanical malfunction; binding or stoppage; spitting pow-
der/gas; a cartridge primer is punctured; a cartridge case is bulged or ruptured;
or the sound on firing does not sound quite right.  Do NOT try one more shot
but unload your firearm and take it and the ammunition to a qualified gunsmith
or send it back to EAA for examination.  Do not assume that the shotgun is
empty merely because you checked the chamber.  You must also check the
bore for any fired shot or wad jammed inside the barrel.

DIRECTION FOR ASSEMBLY
The MP133 comes with the barrel separated from the receiver for transit rea-
sons. You will need to install the barrel to the receiver. A) To do this you will
remove the receiver and stock and forearm / slide assembly from the box and
remove the protective wrapping. B) Then you will remove  the magazine tube
cap / extension. C) Then slide the slide / forearm assemble to the middle of the
slide path so that the bolt is mid way in the ejection port window, Now remove
protective wrapping from the barrel and (D) inset the barrel (barrel extension
end into the receiver and slide the forend / slide back as required so that the
barrel fully enters the receiver and the barrel magazine support aligns and
goes around the magazine tube. Now reinstall the magazine tube cap / exten-
sion. Have your firearms dealer show you how to do this the first time and
always make sure the magazine tube cap / extension is completely tighten
down. See Fig (A, B, C, D)
LOCKING BLOCK PLACEMENT:
During assembly or reassembly make sure the locking lug is place as pictured
(Fig B). Make sure that the firing pin and firing pin washer are held rearward by
the locking lug (Fig B1).
Screw in Chokes Symbols / Markings
The end of the chokes are marked with slashes to determine choke
///// - Extra Full / - Full
// - Improved Modified /// - Modified
//// - Improved Cylinder Cl - Cylinder
BEFORE INSTALLATION OF A CHOKE TUBE MAKE SURE THE SHOTGUN IS
UNLOADED.
The chokes are right hand thread. Make sure that you do not cross thread the
choke. For tightening of a choke tube use a special wrench which completes
your shotgun.
WARNING! MAKE SURE YOU FULLY TIGHTEN THE CHOKE TUBE
Shooting with loosed choke tube can cause its damage or damage of your
shotgun.

							Look into the muzzle. The ring at the surface of the barrel
bore overhangs the surface of the choke tube and should
be visible. The distortion of the ring may indicate the
damage of the choke tube or housing in the barrel.
PERIODICALLY, CHECK TO INSURE THE TUBE IS
FULLY SEATED IN THE BARREL.
After use remove the choke tube and clean the choke
tube threads and location in the barrel where the choke
tube thread into.  Only use choke tube lube for
lubrication. Only use IC choke tube with slug.
REMEMBER the choke tubes and the location in the
barrel need careful handling for prevention of casual
deformation at the thin-wall sections. Needlessly do not
leave a barrel without a choke tube being in place.
If you would like to buy extra choke tubes (skeet, trap,
extra full, etc.) call; Colonial @ 1-800-949-8088
DIRECTION FOR DISASSEMBLY
Make sure the gun is unloaded and pointed in a safe direction. Make sure the
safety is on. There is no excuse for not being careful.
Fig 1: With the bolt in the forward position unscrew the magazine tube cap /
extension and remove. Grasp the barrel and remove the barrel by pulling the
barrel and barrel extension out of the receiver.
Fig 2: Grasp the forend / slide and pull the bolt and action bar forward out of
the receiver and remove the bolt and action bar and forend / slide assembly
from the slide guide tube. Be careful because once the bolt is removed from
the receiver all the pieces from the assembly are free to separate. We suggest
you keep the gun with the bolt up when you remove the assembly so the as-
sembly does not separate.
Fig 3: The trigger assembly can be removed with the barrel and bolt removed
or without the barrel and bolt removed. To remove the trigger assembly all you
do is remove the two pins that hold the trigger assembly in place and pull the
trigger assembly from the receiver. The pins can be removed with a hammer
and a punch.
TO LOAD YOUR SHOTGUN
1.  Make sure the shotgun is pointed in a safe direction at all times, the safety is
engaged, and never allow fingers or objects to contact trigger.
2.  Do not load shotgun until you are ready to fire.
3.  Do not disengage the safety until you are ready to fire.
4.  Make sure the ammo that you are using is the correct
size and gauge. The barrel is marked with the gauge
and chamber size, barrels marked 3.5 will also use 2 3/
4 or 3 or 3.5 shot shells.
