BASIC SAFETY RULES

1. NEVER POINT A FIREARM AT SOMETHING THAT IS NOT SAFE TO SHOOT.

1. Never let the muzzle of a

firearm point at any part of your body or at another person. This is especially important when loading or unloading the firearm. When you are shooting at a target, know what is behind it. Some bullets can travel over a mile. If you miss your target or if the bullet penetrates the target, it is your responsibility to ensure that the shot does not cause unintended injury or damage.

2. ALWAYS TREAT A FIREARM AS IF IT WERE LOADED.

2. Never assume that a firearm is unloaded. The on-

ly certain way to ensure that a firearm is empty is to open the chamber and visually examine the inside to see if a round is present. Removing the magazine will not guarantee that a pistol is unloaded or cannot fire. Shotguns

and rifles can be checked by cycling or removing all rounds and by then opening the chamber so that a visual inspection of the chamber for any remaining rounds can be made.

3. STORE YOUR FIREARM SO THAT CHILDREN CANNOT GAIN ACCESS TO IT.

3. It is your responsibility to insure that children under the age of 18 or other unautho

rized persons do not gain access to your firearm.

separate locked location.

person.

4. NEVER SHOOT AT WATER OR AT A HARD SURFACE.

4. Shooting at the surface of water or at a rock or oth-

er hard surface increases the chance of ricochets or fragmentation of the bullet or shot, which can result in the projectile striking an unintended or peripheral target.

5. KNOW THE SAFETY FEATURES OF THE FIREARM YOU ARE USING, BUT REMEMBER: SAFETY DEVICES ARE NOT A SUBSTITUTE FOR SAFE HANDLING PROCEDURES.

know and use the safety features of the particular firearm you are handling, but ac cidents can best be prevented by following the safe handling procedures de-

iarize yourself with the proper use of this or other firearms, take a Firearms Safety Course taught by an expert in firearms use and safety procedures.

ammunition may result in exposure to lead and other substances known to cause

6. PROPERLY MAINTAIN YOUR FIREARM.

6. Store and carry your firearm so that dirt or lint does not

accumulate in the working parts. Clean and oil your firearm, following the instructions provided in this manual, after each use to prevent corrosion, damage to the barrel or accumulation of impurities which can prevent use of the gun in an emergency. Always check the barrel prior to loading to ensure that it is clean and free from obstructions. Firing against an obstruction

can rupture the barrel and injure yourself or others nearby. In case you hear an unusual noise when

shooting, stop firing immediately, ingage the manual safety and unload the firearm. Make sure the chamber is free from any obstruction or possible bullet blocked inside the barrel due to defective or improper ammunition.

7. USE PROPER AMMUNITION.

7. Only use factory-loaded, new ammunition manufactured to industry specifications:

CIP (Europe and elsewhere), SAAMI (U.S.A.). Be certain that each round you use is in the proper caliber or gauge and type for the particular firearm. The caliber or gauge of the firearm is clearly marked on the barrels of shotguns and on the slide or barrel of pistols. The use of reloaded or remanufactured ammunition can increase the likelihood of excessive cartridge pressures, casehead ruptures or other defects in the ammunition which can cause damage to your firearm and injury to yourself or others nearby.

10. AVOID ALCOHOLIC BEVERAGES OR JUDGMENT OR REFLEX IMPAIRING MEDICATION WHEN SHOOTING.

10. Do not drink and shoot. If you take medication that

can impair motor reactions or judgment, do not handle a firearm while you are under the influence of the medication.

11. NEVER TRANSPORT A LOADED FIREARM.

11. Unload a firearm before putting it in a vehicle.

Hunters and target shooters should load their firearm only at their destination. If you carry a firearm for self-protection, leaving the chamber unloaded can reduce the chance of accidental discharge.

8. ALWAYS WEAR PROTECTIVE GLASSES AND EARPLUGS WHEN SHOOTING.

8. The chance that gas, gunpowder or metal fragments

will blow back and injure a shooter who is firing a gun is rare, but the injury that can be sustained in such circumstances is severe, including the possible loss of eyesight. A shooter must always wear impact resistant shooting glasses when firing any firearm. Earplugs help reduce the chance of hearing damage from shooting.

9. NEVER CLIMB A TREE, FENCE OR OBSTRUCTION WITH A LOADED FIREARM.

9. Open and empty the chamber of your firearm before

climbing or descending a tree or before climbing a fence or jumping over a ditch or obstruction. Never pull or push a loaded firearm toward yourself or another person.

12. LEAD WARNING.

11. Discharging firearms in poorly ventilated areas, cleaning firearms, or handling

birth defects, reproductive harm, and other serious physical injury. Have adequate ventilation at all times. Wash hands thoroughly after exposure.

DESCRIPTION

The AL391 Urika semi-automatic shotgun, 12 and 20 gauge, comes with the following features:

STREAMLINED RECEIVER DESIGN

The skilfully rounded shape of the receiver promotes instinctive and quick target acquisition. The matted anti-glare black-finish of the upper and lower parts of the receiver highlight the bright finish of the sides to confer to the Beretta AL391 Urika a new appearance and distinctive character.

GAS OPERATION SYSTEM WITH EXHAUST VALVE

STOCK

The stock is designed to accept either a plastic butt-plate or a rubber recoil pad with out any adjustment. By assembling rubber recoil pads of different thicknesses, one can modify the length of pull.

STOCK DROP AND CAST SPACERS

The design of the fiber-glass reinforced technopolymer receiver - stock spacer and fying their assembly position. Different stock drop and cast dimensions can be ob-

tained using the extra set of spacers supplied.

The unique gas operation system, with gas cylinder and self cleaning piston, is provided with a self-cleaning exhaust valve which automatically expels the excess gas of the most powerful cartridges: The result is that the shotgun, without any adjustment , fires everything from the light 24 gr. (7/8 oz.) loads to the powerful 57 gr. (2 oz.) 3” Magnum 12 ga. shotshells. The exhaust valve assembly remains attached to the gas cylinder, thus allowing easy and quick disassembly and reassembly of the shotgun.

RECOIL DAMPER

The elastic recoil damper reduces stress from the impact of the breech bolt on the receiver and absorbs part of the vibrations normally transmitted to the shooter.

TRIGGER PLATE

The high strength fiber-glass reinforced technopolymer trigger plate offers many advantages: Self-cleaning property, high absorption of vibrations and more comfort to the touch in cold weather conditions. The large opening of the trigger guard allows the use of gloves.

CUT-OFF DEVICE

The cut-off control is positioned on the left side of the receiver: It can be engaged when the breech bolt is positioned in the closed position with the use of one hand. If the cut-off is accidentally left engaged, automatic reloading after the first shot will disengage it.

ACCESSORIES

The AL391 Urika is supplied with a modern design case and a complement of accast spacers, grip cap (wood stock field models only), stock swivels (field models on

ly), 25 ml. Beretta Gun Oil, valve hook wrenches and, for Mobilchoke of 5 choke tubes with special spanner.

NOTICE: The AL391 Urika barrels are not interchangeable with those of former models (AL 390, A 390 ST, A 304 etc.)

REVERSIBLE SAFETY BUTTON

The cross-bolt safety button can be assembled for standard right-hand use or reversed for left-hand use.

OPERATION

ASSEMBLING THE BARREL

The Beretta AL391 Urika semi-automatic shotgun is factory packed with the barrel separate from the stock / receiver / fore-end assembly.

Assemble the barrel to the stock / receiver / fore-end assembly as follows:

CAUTION: If, for any reason, the breech bolt is open and the fore-end is separated from stock / receiver assembly, avoid pressing the breech bolt release button and be careful to keep your fingers away from the ejection port. Should the breech bolt release button be pressed in this condition, the breech bolt would slam forward and would stop only when the cocking handle hits the

Unscrew (counterclockwise) the fore-end cap from the stock / receiver / fore-end assembly. (Fig. 1)

Pull the fore-end off the magazine tube. (Fig. 2)

Remove the piston. (Fig. 3)

Check that the carrier stop push button is completely depressed. If not, depress it completely. (Fig. 4)

Pull the cocking handle backward to bring the breech bolt in the OPEN position. (Fig. 5)

CAUTION: Should the breech bolt release button be pressed in this condition, the breech bolt would slam forward and would stop only when the cocking handle hits the forward rim of the ejection port. This could damage both the handle and receiver.

Insert the piston into the gas cylinder. (Fig. 6)

Partially slide the barrel tang into the receiver, taking care that the piston does not drop out of the gas cylinder and that the magazine tube cap shaft enters the piston hole as well as that of the gas cylinder and the valve assembly. (Fig. 7)

Slide the barrel tang home into the receiver. (Fig. 8)

Slide the fore-end into place over the gas cylinder, valve assembly and magazine tube. Check that the fore-end is perfectly centered on the receiver face. The foreend is correctly assembled when there is no space left between the parts. (Fig. 9)

Place the front swivel ring (if desired and supplied) on the fore-end flange and com pletely tighten the fore-end cap. (Fig. 10)

Close the breech bolt by depressing the breech bolt release button, keeping your fingers away from the ejection port. (Fig. 11)

WARNING: All assembly, disassembly and maintenance procedures should be carried out with the firearm unloaded (magazine tube empty, receiver empty and cartridge chamber empty). Check that the firearm is unloaded by looking through the ejection port, the loading gate and the chamber.

WARNING: During the assembly, disassembly and maintenance procedures, never point a firearm at someone or at hard and flat surfaces. Treat the firearm as if it were loaded. (See points 1, 2 and 4 of the BASIC SAFETY RULES).

CAUTION: While depressing the breech bolt release button to close the breech bolt, make sure that the cut-off is not inadvertently engaged. Should this occur, the breech bolt would be kept OPEN by the cut-off lever. In this case, always keeping your fingers away from the ejection port, close the breech bolt by operating the cut-off. (Fig. 12)

Keeping the breech bolt retracted approximately 2 cm (1 inch), depress the trigger to lower the hammer. (Fig. 13)

LOADING THE FIREARM

WARNING: Before loading the firearm, practice the following loading proce-

dures without the use of ammunition. Never handle a loaded firearm until you are fully familiar with the loading procedures. Before loading the shotgun, make sure that the safety is engaged. Always point the firearm in a safe direction. (See points 1, 2 and 4 of the BASIC SAFETY RULES).

WARNING: Always keep your fingers away from the trigger and keep the trigger free from any contact when you do not intend to fire.

To fire, disengage the safety and pull the trigger.

When the last round has been fired, the breech bolt remains open, thus signalling that the magazine is empty. (Fig. 19)

Engage the safety and, if required, reload the firearm as indicated.

USE OF THE CUT-OFF DEVICE

The cut-off device allows one to extract a live round from the cartridge chamber and lock the breech bolt open for safety or to replace the round in the chamber, without feeding a new round from the magazine.

Retract the breech bolt by means of the cocking handle until it hooks into the OPEN position. (Fig. 14)

Engage the safety by pushing the safety button until the red ring disappears. (Fig. 15)

WARNING: When the safety button shows the red ring, the firearm is in the FIRE position.

NOTICE: The safety can be engaged only when the hammer is cocked.

Insert the first round into the cartridge chamber through the ejection port. (Fig. 16)

Depress the breech bolt release button to lock the breech bolt, keeping fingers away from the ejection port. (Fig. 17)

WARNING: The firearm is now loaded and ready to fire. Always keep your fingers away from the trigger and keep the trigger free from any contact when you do not intend to fire. Never point the firearm at something that is not safe to shoot. (See points 1, 2 and 4 of the BASIC SAFETY RULES).

NOTICE: The manufacturer assumes no responsibility for any injury or property damage resulting from improper or careless handling, intentional or accidental discharge of the firearm.

WARNING: The firearm is now loaded with a cartridge in the chamber and the safety is engaged. Never point a firearm at something that is not safe to shoot. (See points 1, 2 and 4 of the BASIC SAFETY RULES).

Make sure that the safety is engaged.

Engage the cut-off by depressing the cut-off lever (round side). (Fig. 20)

Retract the breech bolt by means of the cocking handle to extract the live round from the cartridge chamber and eject it through the ejection port. At the end of its travel, the breech bolt is hooked into the OPEN position by the carrier which is locked by the cut-off device. Feeding from magazine is blocked. (Fig. 21)

Under safety conditions, insert the extracted cartridge or another cartridge into the cartridge chamber.

Keeping fingers away from the ejection port, depress the cut-off lever to close the breech bolt. (Fig. 12)

WARNING: The firearm is loaded and ready to fire again. Make sure that the safety is fully engaged. Never point a firearm at something that is not safe to shoot. (See points 1, 2 and 4 of the BASIC SAFETY RULES).

To fire, disengage the safety and pull the trigger.

NOTICE: If the firearm is to function properly, it is recommended that the cutoff be used as described above. In particular, it must be remembered that the breech bolt, when held OPEN by the cut-off, can be closed only by operating the cut-off lever.

CAUTION: Should the breech bolt remain open, check that the cut-off is not inadvertently engaged. If it is, always keeping your fingers away from the ejection port, close the breech bolt by operating the cut-off button. (Fig. 12)

Insert through the loading gate the other rounds by placing each round on the carrier and pressing it down and forward into the magazine tube until it engages the stop tooth. (Fig. 18)

UNLOADING THE FIREARM

WARNING: The firearm is loaded and ready to fire. Always keep your fingers

WARNING: Check that the firearm is unloaded (cartridge chamber empty, re-

ceiver empty, magazine tube empty). Check that the firearm is unloaded by looking through the ejection port, the loading gate and the chamber. If the shotgun is not unloaded, unload it as described in the chapter “Unloading the firearm”. Lower the hammer on the unloaded gun by pulling the trigger.

WARNING: Never point a firearm at someone or at hard and flat surfaces. Treat the firearm as if it were loaded. (See points 1, 2 and 4 of the BASIC SAFETY RULES).

WARNING: Excess oil and grease obstructing the bore even partially are very dangerous when firing and may cause damages to the shotgun and serious injury to the shooter and bystanders. Never spray or apply oil to the shotshells. Use lubricants properly: you are responsible for the proper care and maintenance of your firearm.

Every 3000-5000 rounds (according to the type of ammunition used) and in any

TRIGGER PLATE

After use, thoroughly clean the barrel bore by passing a swab through it to remove combustion residues. If necessary, use a cleaning rod with bronze brush and/or a patch soaked in a bore cleaning solvent.

Thoroughly clean the barrel tang locking shoulder.

Pull a clean soft patch through the barrel bore.

Lightly lubricate the barrel bore by pulling through it a soft clean patch treated with Beretta gun oil.

CAUTION: Do not apply excess oil: accumulation of oil attracts dirt which can plug the barrel and interfere with the functioning and reliability of the gun.

GAS CYLINDER, PISTON, MAGAZINE TUBE CAP SHAFT, EXHAUST VALVE ASSEMBLY

CAUTION: Magnum cartridges and particularly Super Magnum (3”) shotshells

produce a high amount of combustion gases. The particular composition of some Super Magnum shotshells’ powder can generate a strong deposit of combustion residues. The parts of the shotgun which, coming into contact with the gases, are more affected by the combustion residues are the gas cylinder (inside) and the piston with its bushing.

Check that the piston slides freely inside the gas cylinder.

Carefully clean the inner side of the gas cylinder with a bronze brush sprayed with Beretta gun oil.

When all combustion residues are removed, clean the inside of the gas cylinder with a soft cloth.

Carefully clean the piston and check that the piston bushing can move freely in its housing.

If necessary, also clean the exhaust valve and the magazine tube cap shaft.

CAUTION: Do not oil these parts.

Lightly oil the parts with Beretta gun oil.

CAUTION: Do not apply excess oil: accumulation of oil attracts dirt which can plug the barrel and interfere with the functioning and reliability of the gun.

MOBILCHOKE®TUBES

REASSEMBLY

Insert the valve shaft into the gas cylinder, letting the shaft lugs enter the cylinder recesses. (Fig. 33)

Place the valve centering ring, the valve and the valve spring around the valve shaft .

Make sure that the valve is assembled with the outside recess turned to contain the first coil of the spring. (Fig. 34)

Manually screw the valve nut on the valve shaft until tight.

Using the supplied hook wrench, tighten the valve nut against the valve centering ring.

Manually screw the valve counter-nut on the valve shaft until tight against the valve nut.

Keeping the valve nut tight using one of the two hook wrenches, tighten the counter-nut against the nut with the other wrench. (Fig. 35)

MAGAZINE CAPACITY

The magazine tube capacity of the AL391 Urika (which has a three-round capacity) has been limited to two rounds by the application of a plug in order to comply with the sporting gun laws in force in many countries. This plug, which is factory mounted, reduces the capacity of the AL391 Urika to no more than three rounds (two in the magazine, one in the chamber). In some areas, shooting is allowed only with shotguns having a capacity of no more than two rounds. To use the AL391 Urika in these areas, it will be necessary to limit the magazine capacity to only one round. It is possible to increase the magazine capacity from two to three rounds in the countries where it is allowed.

NOTICE: These operations must be carried out by a competent gunsmith.

NOTICE: Beretta Mobilchoke®SP (Steel-Proof) screw-in chokes tubes have

been specially designed to take the punishment of non-toxic steel shot. For best results with steel shot, Beretta recommends a modified choke. Full choke constriction when using steel shot does not increase pattern density and often distorts normal pattern density associated with lead. Remember that standard old type Beretta Mobilchoke®tubes were not designed for steel shot. Before shooting steel shot cartridges check that the Beretta Mobilchoke®tubes are marked SP.

CHANGING AND CLEANING THE CHOKES

WARNING: Check that the firearm is unloaded (cartridge chamber empty, re-

WARNING: Never look into the muzzle or change tubes on a loaded gun even with safety engaged.

WARNING: Never point a firearm at someone or at hard and flat surfaces. Treat the firearm as if it were loaded. (See points 1, 2 and 4 of the BASIC SAFETY RULES).

Unscrew (counterclockwise) the choke using the supplied spanner. (Fig. 39)

Carefully clean the choke housing. If necessary, use a patch sprayed with Beretta gun oil.

Carefully dry the choke housing using a soft patch.

Insert the desired choke into the choke housing, checking that it is perfectly clean inside and outside. (Fig. 40)

Manually screw on (clockwise) the choke. Tighten it with the multiple spanner.

WARNING: During the hunting or shooting day, under safe conditions (firearms unloaded with cartridge chamber empty, receiver empty, magazine empty and breech bolt in OPEN position) check whether the choke has worked loose. Should this happen, the choke must be tightened again using the supplied spanner.

WARNING: Remember that you should never use a Mobilchoke®barrel with- out a Mobilchoke®tube inserted. Shooting without the choke tube is dangerous and can damage the barrel’s internal screw thread irreparably.

STOCK DROP AND CAST MODIFICATION

The Beretta AL391 Urika semi-automatic shotgun is factory set with a heel drop of 55 or 60 mm. (2.16” or 2.36”) (field, sporting, skeet models), of 40 mm. (1.57”) (trap models) and cast-off (right-handed shooters).

The components which determine the drop and the cast are:

¿ Receiver-stock spacer made of technopolymer, fiber-glass reinforced. ¡ Stock metal plate.

Both the spacer ¿ and the plate ¡ are designed to secure two different drops with cast-off or with cast-on (for left handed shooters) depending on how they are assembled. Other measures of stock drop can be obtained using the supplied extra set of spacers.

CHANGING THE STOCK DROP AND CAST SPACERS

NOTICE: The “DX” mark on the spacer and on the plate means “cast-off”, the

“SX” mark means “cast-on”. The stock drop measures are in millimetres. The stock drop and cast of the spacer ¿ must always correspond to those of the metal plate ¡.

NOTICE: Stock drop and cast modification must be carried out by a competent gunsmith.

NECESSARY TOOLS

Screwdriver.

Hexagonal tube spanner (13 mm).

Torque wrench (suggested).

Remove the recoil pad using the screwdriver.

Disassemble the stock using the spanner and take off the spacers.

Put the spacer ¿ around the stock bolt tube. Make sure that the spacer shows on the top the drop and cast wanted (“C-60-DX” in the drawing).

Put the rear plate ¡ and the washer in the back hole of the stock until the plate reaches its own seat in the stock. Make sure that the plate shows on the top the same drop and cast of the spacer on the top (“C-60-DX” in the drawing).

Use the screwdriver to center the plate and the washer.

Assemble the stock, making sure to locate the stock bolt tube through the rear plate ¡ and the washer. Also make sure that the front spacer ¿ is centered between the stock and the receiver. (During this operation keep the shotgun vertical with the barrel down).

Using the spanner, screw on and tighten the stock retaining nut with a torque of about 1,6/1,8 kgm (11.6/13.0 Ftlb) (Kg meter). A torque wrench is useful for this purpose.

Screw on the recoil pad.

WARNING: The improper observance of this procedure could cause damage to the shotgun and/or injury to the bystanders.

WARNING: Check that the firearm is unloaded (cartridge chamber empty, receiver empty, magazine tube empty). Check that the firearm is unloaded by looking through the ejection port, the loading gate and the chamber. If the shotgun is not unloaded, unload it as described in the chapter “Unloading the firearm”. Lower the hammer on the unloaded gun by pulling the trigger.

RECOIL PAD

The standard plastic butt-plate or rubber recoil pad can be replaced with a rubber re coil pad of different thickness without any adjustment. By assembling rubber recoil pads of different thickness it is possible to modify the length of pull.

NOTICE: This operation must be carried out by a competent gunsmith.

WARNING: Never point a firearm at someone or at hard and flat surfaces.

Treat the firearm as if it were loaded. (See points 1, 2 and 4 of the BASIC SAFETY RULES).

WARNING: Never point a firearm at someone or at hard and flat surfaces. Treat the firearm as if it were loaded. (See points 1, 2 and 4 of the BASIC SAFETY RULES).

The safety button is factory assembled to be engaged by pushing it from the left to the right side of the receiver and disengaged in the opposite direction with the index finger of the right hand (right-handed shooters). By reversing the safety button, the safety is engaged by pushing from the right to the left side of the receiver and is disengaged in the opposite way by using the index finger of the left hand (left-handed shooters).

To invert the safety button: Cock the hammer. Keeping the safety plunger depressed with a drift punch, push the safety out of its housing (from the right to the left side of the firearm).

CAUTION: The safety plunger spring, when mounted, is in a compressed condition. Take care not to lose the plunger and its spring.

NOTE:

Reverse the safety and insert it into its housing from the left to the right side of the firearm and click it into position, keeping the safety plunger depressed.

NOTICE: This operation must be carried out by a competent gunsmith.
