Assembling The Barrel

The Beretta AL 390 semi-automatic shotgun is factory packed with barrel separate from the stock - receiver - fore-end assembly.

Before proceeding with the assembly of the barrel to the stock - receiver - fore-end assembly, carefully read the "FUNCTIONING" chapter and check the main component parts in the "NOMENCLATURE" table.

Please note: The stock - receiver - fore-end assembly is packed with breech bolt CLOSED, hammer lowered and safety off (safety can be engaged only when hammer is cocked).

Make sure that safety is off (this happens when the red ring is visible). Check that the hammer is lowered by pulling the trigger. If, for any reason, the breech bolt is OPEN, avoid to press 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 jump forward and would stop only when the cocking handle hits the forward rim of the ejection port. This could damage both handle and receiver.

Assemble the barrel as follows:

• Check the barrel. Bore and cartridge chamber must be clean and free from obstructions.

• Check that magazine tube and receiver are empty by looking through the loading gate.

• Unscrew (anticlockwise) the fore-end cap from the stock - receiver - fore-end assembly and remove the front swivel, when mounted. 1

• Pull the fore-end off the magazine tube. 2

• Slide the exhaust valve and the piston off the magazine tube cap shaft. 3, 4

• Insert the piston into the barrel gas cylinder. 5

• Pull the cocking handle backward to bring the breech bolt in OPEN position. 6

• Slide the barrel tang into the receiver, holding the barrel and gas cylinder with the right hand to prevent dropping the piston. During this operation take care that the magazine tube cap shaft enters the piston hole as well as the gas cylinder one. 7

• Slide the barrel tang home into the receiver. 8

• Assemble the exhaust valve and spring onto the magazine tube cap shaft. 9

• Slide the fore-end home over the gas cylinder and magazine tube letting the exhaust valve spring protrude from the fore-end flange. 10

• Screw the fore-end cap home clockwise, ensuring that the front swivel ring, when supplied, remains around the base of the cap. 1 f

• Make sure that the cap is screwed up tight.

• Close the breech bolt by depressing the breech bolt release button, keeping your fingers away from the ejection port. 12

Warning: 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, unlocked from the cartridge lever, would be kept OPEN by the cut-off itself through the carrier. In this case, always keeping your fingers away from the ejection port, close the breech bolt operating on the cut-off. 13

• Retract the breech bolt enough to allow a visual check of the cartridge chamber, which should be empty. Be careful where you point the firearm, even though it might not be loaded.

Depress the trigger to lower the hammer. 14

LOADING THE FIREARM

Warning: Always keep your fingers away from the trigger whenever you do not intend to fire. Make sure that the gun is not already loaded by inspecting the cartridge chamber, the magazine tube and the receiver.

• Retract the breech bolt by means of the cocking handle until it hooks into OPEN position. 15

• Engage the safety by pushing the safety button until the red ring disappears (when the red ring is visible it indicates that the firearm is in FIRE position). 16

Please note: the safety can be engaged only when the hammer is cocked.

• Insert through the ejection port the first round into the cartridge chamber. 17

• Depress the breech bolt release button to lock the breech bolt, keeping fingers away from the ejection port. 18

Warning: Make sure not to engage the cut-off inadvertently.

• 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. 19

Warning: The FIREARM IS NOW LOADED AND READY TO BE FIRED

• To fire, disengage the safety and pull the trigger.

• When the last round has been fired, the breech bolt remains OPEN thus signalling that magazine is empty. 20

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

USE OF THE CUT-OFF DEVICE

The cut-off device makes is possible to extract the live round from the cartridge chamber and lock the breech bolt OPEN, for safety reasons or to replace the round into the chamber, while stopping at the same time the feeding of a new round from the magazine.

Warning: THE FIREARM IS LOADED. Check that safety is engaged

• Engage the cut-off by depressing the cut-off lever (round side). 21

• Retract the breech bolt by means of the cocking handle to extract the live round from the cartridge chamber and to eject it through the ejection port. At the end of its travel the breech bolt is hooked into OPEN position by the carrier locked by the cutoff device. Feeding from magazine is blocked. 22

• When safety conditions are restored, insert the extracted cartridge or another one of choice into the cartridge chamber.

• Keeping fingers away from the ejection port, depress the cut-off lever to lock the breech bolt. 13

Warning: THE FIREARM IS LOADED AND READY TO FIRE AGAIN

• To fire, disengage the safety and pull the trigger.

Please note: If the firearm is to function properly, it is recommended that the cut-off is 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 operating on the cut-off lever itself.

UNLOADING THE FIREARM

Warning: THE FIREARM IS LOADED AND READY TO FIRE.Keep your fingers away from the trigger whenever you do not intend to fire.

• Pointing the firearm in a safe direction, check that safety is engaged.

• Engage the cut-off and retract to the end the breech bolt to extract and eject the chambered live round. 21, 22

• Keeping fingers away from the ejection port, depress the cut-off lever to lock the breech bolt. 13

• Pressing down the carrier and at the same time pushing against the cartridge in the magazine, depress the breech bolt release button to ease exit of the cartridges from the magazine tube. 23

• Check that magazine tube and receiver are empty. Then disengage the safety.

• Retract the breech bolt enough to allow a visual check of the cartridge chamber, which should be empty. Be careful where you point the firearm, even though it might not be loaded. Depress the trigger to lower the hammer. 14

DISASSEMBLY

BARREL

Warning: Ensure that the firearm is unloaded (cartridge chamber, magazine tube and receiver empty).

If not, unload the firearm by operating as described in the chapter "UNLOADING THE FIREARM". Check that hammer is lowered.

Disassemble the barrel as follows:

• Retract the breech bolt until it hooks into OPEN position. 15

• Unscrew (anticlockwise) the fore-end cap from the firearm and remove the front swivel, when mounted. 11

• With the left hand, hold down the barrel and with the right hand slide fore-end off the magazine tube. 24

• Slide the exhaust valve with spring off the magazine tube cap shaft. 9

• Grasping the barrel at the height of the gas cylinder, hold the piston inside the gas cylinder with the right thumb to prevent dropping it; slide barrel assembly forward off the stock-receiver assembly. 8

• Slide the piston off the gas cylinder. 5
