USER MANUEL FOR
PUMP ACTION SHOTGUNS
You are now the owner of Berserker Firearms shotgun. Your shotgun has an innovative design and is manufactured of highly quality materials. With regularly performed maintenance and the use of proper ammunition, it will provide you many years of service.
In order to achieve the best performance and reliability with your shotgun, please read and fully understand all of the instructions, safety guidelines, and warnings carefully in this manual. Your shotgun is reliable and safe unless it is handled in a careless or irresponsible manner.
PLEASE REMEMBER IT IS IMPERATIVE THAT THE FIREARM HANDLER BE FULLY EDUCATED AND CONSCIOUS OF THE IMPORTANCE OF EXECUTING PROPER GUN SAFETY RULES WHEN OPERATING ANY FIREARM.
Before using or firing with any live ammunition, you should know and fully understand your shotgun parts, function, and operating mechanisms. So carefully read and fully understand all of the information below about the parts and procedures of using the shotgun safely and effectively.
A GUN OWNER’S RESPONSIBLITY
As the owner of a firearm you have the responsibility and obligation of ensuring that any and all shooting activities are safe for everyone. This requires your personal commitment to carefully read, fully understand, and exercise the principles of proper firearm safety at all times.
The Berserker Firearms shotgun is a gas operated, auto-loading shotgun. It is capable of shooting up to five shots (with the magazine plug removed using 1 3/4″ loads) in rapid succession with each pull of the trigger. Upon firing, high pressure gas from behind the shot charge passes through two ports in the barrel, through the gas bracket and into the gas cylinder. High pressured gas forces the gas piston rearwards, applying pressure to the piston rod. As the piston rod moves rearward, it pushes the bolt assembly rearward, operating the action. As the bolt assembly moves rearward, it re-cocks the hammer and ejects the fired shell. After full rearward travel, the bolt assembly returns forward, picking up a new shell from the magazine and chambering it automatically. After the last shell has been fired, the bolt assembly locks to the rear, instead of returning forward. This facilitates speedy reloading.
EXTERNAL CONTROL PARTS
(“Right” and “Left” refer to the shotgun as seen by a shooter holding it in the firing position)
Cross Button Safety:
Located behind the trigger on the trigger housing.
When the red ring around it is visible, it means that the cross button safety is disengaged “OFF” and shotgun is ready to fire.
To engage the cross button safety, push it until the red ring disappears and it moves no longer to the safety position.
Now the safety is “ON”, trigger cannot be pulled and the shotgun cannot be fired.
⦁ Always keep the cross button safety ON (herein after will be referred as only “safety ON”) until you are actually ready to fire and the muzzle is pointing at the target.
⦁ Make sure that you understand how all controls work before you attempt to load the shotgun.
⦁ Keep the muzzle pointed in a safe direction and your finger off the trigger when operating the safety. Malfunctions which may cause a shotgun to fire is engaged or disengaged are rare but can happen. Even if an accidental firing should occur, nobody will be hurt if you follow this rule.
THREE THINGS TO REMEMBER ABOUT SAFETIES
⦁ NEVER TOTALLY DEPEND ON A MECHANICAL SAFETY. It is not a substitute for proper shotgun handling. Like all mechanical devices the safety is subject to breakage or malfunction and can be defeated by wear, abuse, dirt, corrosion, incorrect assembly of the shotgun, improper adjustment or repair, or lack of maintenance.
⦁ NO MECHANICAL SAFETY IS “CHILDPROOF” OR “FOOLPROOF”. No safety ever invented can be relied upon to prevent an accidental shooting by a determined child or a grown up individual “playing” with a shotgun.
⦁ TREAT EVERY SHOTGUN AS IF YOU EXPECT ITS MECHANICAL SAFETY NOT TO WORK. You will be astounded at how cautious you become, and how little tolerance you will have for the complacency of others.
Action Release Control:
The action lock lever is located on the left side of the trigger housing just rearward of the trigger guard. The action lock lever allows the action to be unlocked and opened for inspection or unloading without pulling the trigger. The action may be opened by depressing the lever and pulling the forearm rearward. (1)
NOTE: During firing, the action unlocks automatically after the hammer falls and the action can be cycled without depressing the action lever.
Carrier: Located on the underside of the receiver, in front of the trigger guard. Carrier is pushed into the receiver for loading the shotgun.
Trigger: Located in the trigger guard. When the shotgun is loaded, the safety disengaged, and the trigger pulled, shotgun will fire.
Magazine Cap: Located in front of the forearm and under the barrel. Ii is screwed (clock-wise) over the magazine tube to keep the forearm and barrel properly in place.
Your new pump action shotgun is packed dismounted in its box, i.e. barrel is separated from the stock-receiver-forearm assembly. To attach the barrel, first remove all parts from the plastic bags.
Before proceeding with the assembly of the shotgun, carefully check the “ Nomenclature “ and read “ Safety Measures “ sections.
Before assembling the shotgun, check the barrel. Bore and cartridge chamber must be clean and there should no obstructions in them.
Assemble the shotgun as follows:
⦁ Unscrew the magazine cap (counter-clockwise) and remove it from the magazine tube.
⦁ Insert the barrel extension into the receiver. While doing this, be sure the barrel extension seats between the bolt and the receiver and barrel port ring is aligned with the magazine tube. Continue to slide the barrel into the receiver until the barrel extension seats completely inside the receiver. (2)
⦁ Screw the magazine cap (clock-wise) so that the forearm and barrel tie held properly in place. The shotgun is now assembled and ready for use.
Magazine plug when assembled decreases the capacity of the shotgun to 2+1 for safety reasons or for the regulations varying from country to country.
PS. magazine plug is optional. Consult your dealer about your country’s laws regarding use of this.
It is recommended to have your migratory magazine plug assembled by a qualified gunsmith. Assemble the magazine plug as follows:
⦁ Unscrew the magazine cap.
⦁ Insert the polymer rod, making sure the head is centered in the end of the magazine tube.
⦁ Replace the magazine cap. To remove the plug, reverse the procedure above.
⦁ Bolt does not slide forward
⦁ There is a gap between fore-end and receiver
⦁ Barrel extension protrudes from the receiver,
which means you have not assembled the shotgun properly. In such a case, immediately reverse assembly procedures and re-assemble your shotgun making sure that the barrel is completely inserted into the receiver, fore-end is completely in place and there are no gaps. If you still cannot assemble the shotgun properly take it to a qualified gunsmith for help.
**After you assembled your shotgun or if you are taking it to a gunsmith for help, make sure that you keep the safety “ON”
NOTE: To disassemble the shotgun, reverse the above assembly procedure. To disassemble the bolt; slide the bolt and the action bar forward and remove them from the magazine tube-receiver assembly after the barrel is removed. While doing this, be careful since the bolt may fall from the action bar. Therefore keep the bolt up during this operation. Then the bolt can be easily removed from the action bar with your hand.
LOADING THE SHOTGUN
Always keep your fingers away from the trigger if you do not intend to fire.
⦁ Always check cartridge chamber, magazine tube and receiver to see that the shotgun is not already loaded.
⦁ After you load the shotgun, always point the barrel in a safe direction before you aim at your safe intended target.
⦁ Always use the correct ammo for which your shotgun is chambered.
⦁ Always keep the safety ‘ON’ while loading your shotgun.
Load the shotgun as follows:
⦁ Put the safety “ON” if it is disengaged.
⦁ Pull the forearm fully backwards and insert the first round through the ejection port into the cartridge chamber. (3)
⦁ Turn the shotgun upside down so that the trigger is facing you. By depressing the carrier, into the magazine tube until the last cartridge engages the stop tooth. (4)
Shotgun is now loaded and ready to be fired.
To fire; aim at your intended safe target, disengage safety and pull the trigger. (First see, firing section) After firing cartridge, the forearm should be pulled fully backwards to feed the next round from the magazine tube to the cartridge chamber. When the last round is fired no cartridge will be fed from the magazine tube, but never rely on this and check the cartridge chamber and magazine tube to assure that they are empty.
FIRING THE SHOTGUN
⦁ When pumping and firing, keep your fingers and other objects away from the path of the bolt since it moves back and forward with considerable force and velocity.
⦁ Keep the safety ’ON’ until you are actually ready to fire and aimed at your safe intended target.
⦁ You need to pump the shotgun each time you fire to feed the next round from the magazine tube to the cartridge chamber.
Fire with your shotgun as follows;
⦁ Engage safety and load your shotgun. (see Loading section)
⦁ Pump the shotgun by pulling the forearm fully backwards.
⦁ Wear eye and ear protection, and aim at your safe intended target.
⦁ Disengage safety and get ready for shooting.
⦁ Press the trigger and the shotgun will fire.
⦁ To fire the next round, pump the shotgun by grasping the forearm and pulling it fully backwards, so the next round is fed to the cartridge chamber.
It is not uncommon while loading or firing any pump action shotgun to experience a malfunction in which an unfired or fired cartridge case becomes jammed between the bolt and the barrel. Clear such a stoppage as follows. Point the muzzle in a safe direction. Put the safety “ON”. If possible, engage the action release control button to prevent the next cartridge in the magazine from being released and adding to the jam. Pull back the bolt and hold or lock it to the rear. The jammed cartridge or case can then be removed by shaking it out, or picking it out with your fingers.
If the trigger is pulled and a “click” is heard but a chambered cartridge fails to fire, follow the below instruction.
⦁ Point the shotgun in a safe direction.
⦁ Engage safety.
⦁ Wait 30 seconds.
⦁ Eject the cartridge from the chamber by pressing the action release button and by pulling the for-end backward. Examine the cartridge primer. If it has been deeply indented by the firing pin, the cartridge is defective. If it has been indented lightly or not at all, rechamber the cartridge and try again.
⦁ If still it does not fire, unload the shotgun and take it to a qualified gunsmith.
⦁ When you are firing, if you notice that the sound of any cartridge is considerably louder or softer than the previous one, stop firing and do not load the shotgun anymore. In such a case, follow the below instruction.
⦁ Point the shotgun in a safe direction.
⦁ Engage safety.
⦁ Follow the instructions in the “unloading section” and unload the shotgun completely.
⦁ With the shotgun unloaded, check the barrel for blockage or damage. If you notice any damage or malfunction in the shotgun take it to a qualified gunsmith.
⦁ Shotgun is loaded and ready to fire. Keep your fingers off the trigger and keep the safety ON.
⦁ During unloading, never allow fingers or any object to contact the trigger. Keep the muzzle pointed in a safe direction at all times.
Unload your shotgun as follows;
⦁ Point the shotgun in a safe direction and engage the safety.
⦁ Depress the action release control button (1) and pull the forearm rearward, slowly, until the live round is completely withdrawn from the chamber and visible in the ejection port, and then remove it.
⦁ Continue pulling the forearm rearward to release the next round onto the carrier. Turn the shotgun so that ejection port faces downwarc4s to allow the released round to drop out through the ejection port.
⦁ Push the forearm completely forward, closing the bolt without a shell being chambered.
⦁ To eject the cartridges from the magazine tube, turn the shotgun over so the trigger guard is upward and the shotgun remains pointed in a safe direction. With one of your hand depress the carrier. With your other hand slowly pull the forearm until you feel that the carrier stays depressed at the bottom by itself. (6)
⦁ Then remove your hand that you depressed the carrier and pull the forearm fully rearwards to eject the cartridge from magazine tube. (7)
⦁ Repeat this procedure until no more cartridges are ejected from the magazine tube.
