We are pleased that you have chosen a Browning B-80 Semi-Automatic Shotgun. It is certainly a gun that you can be proud of. It incorporates Browning’s traditional quality and craftsmanship, and is made using the finest materials and manufacturing methods. With a reasonable amount of care, your B-80 should give you many years of dependable, enjoyable service. Please feel free to write us immediately if you have any important observations regarding its performance and operation.
As a gun owner, you accept a set of demanding responsibilities. How seriously you take these responsibilities can be the difference between life and death. Mistakes made with guns are final and cannot be paid for with money or regret. There is no excuse for careless or abusive handling of any firearm. At all times handle this shotgun with intense respect for its power and potential danger.
NEVER TRUST 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 B-80 has a ‘cross bolt’ “safety” which blocks the gun’s trigger. See page 21 for instructions on operation of this gun’s “safety.
ALWAYS VISUALLY CHECK YOUR SHOTGUN'S CHAMBER AND MAGAZINE to be certain that they do not inadvertently contain any ammunition. Open the action, invert the shotgun and inspect the magazine and chamber. Be sure no live round is in the chamber, feed mechanism or magazine. Keep the "safety" in the "on safe"position. WHENEVER YOU HANDLE A FIREARM, OR HAND IT TO SOMEONE, ALWAYS OPEN THE ACTION IMMEDIATELY, and visually check the chamber, receiver and magazine to be certain they do not contain any ammunition.
the barrel to be sure it is clear of any obstruction. It takes only a small obstruction to dangerously increase pressures. 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. See “Cleaning Suggestions” on page 32. ALWAYS UNLOAD YOUR SHOTGUN WHEN NOT IN USE. REFER TO PAGE 30 OF THIS INSTRUCTION BOOKLET EXPLAINING THE UNLOADING OF YOUR SHOTGUN. As a safety precaution it is preferable to disassemble your gun for storage.
loaded in accordance with standards established by SAAMI (Sporting Arms and Ammunition Manufacturers Institute). DO NOT PUT A 20 GAUGE SHELL IN A 12 GAUGE GUN. Store all shells of different gauges in completely separate and well-marked containers. Do not store shells of mixed gauges in a common container or in your pockets. EXAMINE EVERY SHELL YOU PUT IN YOUR GUN! The most certain way to bulge or rupture a barrel is to drop a 20 gauge shell into a 12 gauge chamber.
DO NOT SNAP THE HAMMER 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. KEEP YOUR FINGER AWAY FROM THE TRIGGER WHILE UNLOADING, LOADING OR UNTIL YOU ARE READY TOSHOOT. 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.
damage. Wear hearing protectors to protect your ears from loud noise and shooting glasses to protect your eyes from flying particles. 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. DROPPING A LOADED GUN CAN CAUSE AN ACCIDENTAL DISCHARGE even with the “safety” in the “on safe” position.
timid when it comes to gun safety. If you observe other shooters violating any of these safety precautions, politely suggest safer handling practices. BE CERTAIN YOUR GUN 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.
in the instruction booklet and on ammunition boxes. It is your responsibility to secure the most up-to-date information on the safe handling procedures for your Browning gun. Browning cannot assume any responsibility when unsafe or improper arms and ammunition combinations are used. READ AND HEED ALL WARNINGS PERIODIC MAINTENANCE— UNAUTHORIZED SERVICING. Your gun is a mechanical device and is subject to wear and requires periodic inspection, adjustment, and service.
In conventional gun terminology, the position and movement of shotgun parts are described as they occur with the shotgun horizontal and in normal firing position; i.e., the muzzle is forward or front; the butt stock is rearward or rear; the trigger is downward or underneath; the sight is upward or on top. For general parts nomenclature, refer to Figure 1. All figures and schematics will refer to all 12 and 20 gauge E80 Shotguns unless otherwise noted. A. Barrel K. Magazine Tube B.
The serial number of your B-80 shotgun can be found on the left side of the receiver. The Browning B-80 is shown disassembled to the extent necessary in order to follow instructions contained in this book. (See Figure 1) The B-80 was designed to function with all standard factory field loads and target loads.
This shotgun is gas-operated. A portion of the expanding powder gases is bled off through gas ports and used to operate the mechanism. During rearward travel, the bolt extracts and ejects the spent shell and cocks the hammer. During the forward travel the next cartridge is fed from the magazine in the chamber. This operation is semi-automatic; the trigger must be released and pulled for each successive shot. After the last cartridge has been fired, the bolt locks open. This facilitates fast reloading.
CAUTION: KEEP YOUR FINGERS CLEAR OF THE EJECTION PORT AS THE BOLT CLOSES. If the bolt will not lock in the open position, press the carrier release which is located at the rear of the carrier just forward of the trigger guard as shown in Figure 3. Before assembling the B-80, anti-rust compounds should be removed from all metal parts, paying close attention to the barrel interior and the breech area.
your new B-80 have been coated with a rust preventative compound for protection. Browning Gun Oil is ideal for removing this compound and for giving your new gun its first lubrication; however, any quality gun oil may be used. You may have to install a recoil adapter in your B80. B-80’s manufactured prior to 1987 used recoil adapters only on 2 3/4” models as described below. In 1987 the B-80 Plus was introduced. A B-80 Plus is identical if the barrel is inscribed 3” and 2 3/4”.
Replace the forearm and forearm cap assembly. If there has been no recoil adapter installed, and your individual gun will not function reliably with light target loads, you should proceed with the following: Obtain a B-80 12 gauge recoil adapter (Part number PO13350) from your dealer, or from the Browning Parts Department in Arnold, Missouri. This adapter makes the B-80 one of the most versatile shotguns on the market; a shotgun that will shoot virtually every 2 3/4” 12 gauge load.
Refer to the section “To Remove The Bolt Assembly,” page 37. After completing steps one through seven, you are ready to install the adapter. Remove both forearm guide screws from the front of receiver, near the magazine tube. (See Figure 4.) Slide the recoil adapter over the magazine tube so that it conforms to the contour of the front of the receiver, and lines up with the screw holes. Replace screws firmly, but do not overtighten. Refer to page 39 regarding reassembly of bolt assembly and trigger housing.
Remove and set aside the forearm cap assembly which holds the forearm in position on the stock/receiver group. (See Figure 5.) Slide forearm up and remove from the magazine tube. (See Figure 6.
assembly. If you remove the gas piston, replace it so that it stands on its flanges atop the magazine tube. Depress carrier release. Pull the bolt to the rear by means of the operating handle until the bolt locks in the open position. Carefully insert the barrel into the receiver while aligning the barrel guide with the magazine spring retainer and forearm cap stud. (See Figure 7.
Align the forearm with the barrel and carefully slide it over the gas piston and magazine tube. CAUTION: DO NOT APPLY FORCE AS DAMAGE TO THE FOREARM COULD RESULT. ANY RESISTANCE SHOULD BE FOLLOWED BY A VISUAL CHECK FOR ALIGNMENT. (See Figure 8.) Replace the forearm cap assembly. BE CERTAIN THE FOREARM CAP ASSEMBLY IS SCREWED COMPLETELY DOWN SO THAT THE REAR END OF THE FOREARM IS IN FIRM CONTACT WITH THE FRONT END OF THE RECEIVER, (See Figure 9.
For convenience in casing and carrying the dismantled gun, return the forearm to its position on the magazine tube and screw on the forearm cap assembly. You will then have two compact units. One is the barrel; the other is the action with forearm and stock. The cross-bolt “safety” is designed to block the trigger from traveling. In the “off-safe” or “fire” position a red warning band is visible on the left side of the trigger guard alerting the shooter of the gun’s ready-to-fire status.
There are two basic methods for getting a loaded shell into the chamber of a B-80. First, the shell can be directly loaded through the ejection port. Second, a shell can be loaded manually from the magazine. Loading of the magazine is the same for both procedures. CAUTION: AT ALL TIMES DURING THE LOADING PROCEDURE, BE SURE YOUR MUZZLE IS POINTING IN A SAFE DIRECTION AND THE SAFETY IS "ON SAFE.
DO NOT PUT A 20 GAUGE SHELL IN A 12 GAUGE GUN. Store shells of different gauges in completely separate and well-marked containers. See caution number 9 on page 6 of this booklet. Do not store shells of mixed gauges in a common container or in your pockets. LOADING THROUGH THE EJECTION PORT— Pull the operating handle to the rear until the bolt locks in the open position. If the bolt will not lock in rear, press the carrier release.
Insert the second cartridge through the loading port at bottom of receiver as shown in Figure 12. Note: MAKE SURE THAT THE CARTRIDGE IS PUSHED PAST THE CARTRIDGE STOP, AND THE CARRIER IS FREE TO MOVE. (See Figure 13.
Repeat the above procedure until your gun is fully loaded. Your B-80 will hold three 3 inch or three 2 3/4 inch cartridges in its magazine plus one in its chamber. NOTE: A magazine plug restricting the B-80’s magazine capacity to two cartridges is installed at the factory. lnstructions for removing the magazine plug will be found on page 42. LOADING MANUALLY FROM THE MAGAZINE- Make sure the muzzle is pointed in a safe direction.

open, push the cartridge stop button, making sure your fingers are clear of the ejection port. Push the “safety” from left to right or to the “on safe” position. The red band indicating that the B-80 is ready to fire should not show. Insert cartridge of the proper gauge through the loading port at the bottom of the receiver up into the magazine as shown in Figure 12. Make sure the cartridge is pushed past the cartridge stop and that the carrier is free to move.
Pull the operating handle all the way to the rear and eject the chambered cartridge and lower the bolt on the empty chamber. NOTE: It is not necessary or recommended that the remaining cartridges be cycled through the action. That would necessitate depressing the carrier release after each cartridge is ejected. It is easier and safer to invert your B-80, insert your index finger into the loading port and while pushing slightly on the round in the magazine, depress the cartridge stop. (See Figure 14.
separately from the gun beyond the reach of children. To change loads in your B-80, simply eject the chambered cartridge by pulling the operating handle all the way to the rear. Insert the desired cartridge (such as a goose load) of the same gauge through the ejection port into the chamber. Repeated cycling of the bolt’s operating handle alone is not assurance that the B-80 is unloaded. There still may be cartridges in the magazine.
pronounced in the constriction area of the choke and just forward of the chamber, are caused by leading. A normal amount of leading can be expected with today’s high velocity loads and improved wads but this is not serious. If leading should become heavy, it can be removed with a brass bore brush. Spray the bore or the bore brush with a good powder solvent, and scrub the bore until leading is removed.
making sure to wipe gun clean of all finger marks. The wood surfaces can also be wiped with Browning Gun Oil or they can be polished with any quality furniture wax (but not both). Once a year, or after 1000 shots, it is advisable to soak the gas piston in solvent and scrub it with a brass-wire brush to remove accumulated deposits. The gas cylinder and barrel guide should also be thoroughly cleaned and wiped dry. Do not oil.
REMOVING THE TRIGGER HOUSING— WHILE POINTING THE MUZZLE IN A SAFE DIRECTION, MAKE SURE THE CHAMBER AND MAGAZINE ARE EMPTY. Draw bolt fully to the rear and release it by depressing the cartridge stop and bolt release button. Push “safety” to the “on safe” position. With a punch or dowel push the trigger housing retaining pin from either side until it can be grasped and pulled free by hand. (See Figure 15.
Depress the cartridge stop / bolt release button flush with the receiver and lift the trigger housing forward, up, and out of the receiver. (See Figure 16.) REPLACING THE TRIGGER HOUSING— With the bolt closed, and the trigger housing hammer cocked, and the safety in the “on safe” position, insert the mainspring support into position by mating the projection at the rear of the trigger assembly into the recess inside the receiver. (See Figure 17.
HOW TO REMOVE THE BOLT ASSEMBLY— While pointing the muzzle in a safe direction, make sure the magazine and chamber are empty. Place the “safety” in the “on safe” position. Remove forearm and barrel as previously described.
Remove the gas piston by pulling it up and off the magazine spring retainer and forearm cap stud. Remove the trigger housing as previously described under “Trigger Housing.” Remove the operating handle by pulling it straight out and free of the bolt. Grasp the action bar and sleeve and ease assembly forward until bolt clears receiver. Be ready to catch bolt assembly as once it clears receiver it will be free to separate into its three basic components. . .
HOW TO REASSEMBLE THE BOLT ASSEMBLY— Hold bolt with firing pin up and place bolt slide into position by inserting it into the bolt recess. Components should fit flush, as shown in Figures 20 and 21. Insert the bolt and slide assembly approximately half way into the receiver and maintain their position with hand pressure from the side while the action bar and sleeve is slipped over the magazine tube and engaged in the bolt slide. (See Figures 22 and 23.
Engage the link into the action spring follower.
will go all the way back before continuing assembly. If the bolt will not go back freely, remove the assembly and align all components carefully, then repeat procedure. Replace the operating handle into the recess on the bolt. (See Figure 25.) Install the trigger housing, being careful to insert the main spring support into the recess. Depress the cartridge stop and bolt release button. Align all components and replace the trigger assembly retaining pin. (See Figure 26.
Depress the carrier release and draw the bolt rearward until it locks in the open position. Replace the gas piston, barrel, forearm and forearm cap assembly. Your B-80 is shipped with a three shot adapter installed.
BE CERTAIN THE GUN IS NOT LOADED AND “SAFETY” IS “ON SAFE.” WE RECOMMEND THAT SAFETY GLASSES BE WORN. Press the carrier release. Lock the bolt to the rear. Remove the forearm cap assembly, forearm, barrel and gas piston. Place the receiver, loading port up, in a well padded vise. Locate the tip of the magazine spring retainer which projects through its port in the underside of the magazine tube.
Remove the punch and continue turning the magazine retainer and forearm cap stud until three threads are exposed. At this point lay the screwdriver aside and proceed by hand. (See Figure 28.
NOTE: The magazine plug is spring loaded and under tension. Be prepared to use both hands in guiding the spring out of, and back into, the magazine tube once the plug has been removed. To reassemble, simply reverse the foregoing procedure taking care to depress the magazine spring retainer lock spring at the point where it prevents the final turns of the magazine retainer and forearm cap stud. (See Figure 29.
Your shotgun barrels may have been threaded to accept the Browning Invector Interchangeable Choke System. You may confirm this by glancing on the right side of your barrel where the specifications are inscribed, or on the left side of the B-80 breech area where the choke markings are normally located. The word, Invector, denotes that the barrels are threaded. If so, please follow these instructions. DO NOT FIRE THIS SHOTGUN WITHOUT HAVING AN INVECTOR CHOKE TUBE INSTALLED.
BROWNING. USE ONLY CHOKE TUBES MARKED INVECTOR. Replacement or additional lnvector choke tubes and wrenches are available from your Browning dealer, the Browning Service Center near you, or by writing to the Browning Consumer Department, Route 1, Morgan, Utah 84050. (801)543-3200. Canadian customers please call or write to Browning Canada Sports Ltd/Ltee, 3167 De Miniac, St. Laurent, Canada H4S 1S0. (514)333-7261.

screw on the right side of the sight. Then tighten the small screw on the left side of the sight. This is a process of trial and error. Make small adjustments, then check the effect on the point of impact. GUN SHOOTS TO THE RIGHT — Do the same procedure as outlined above, except move the sight to the left by loosening the left screw and tightening the right screw. GUN SHOOTS HIGH — Lower the rear sight by turning the large screw on top of the sight in a clockwise direction.
If your B-80 should require service or repairs, we suggest you first contact a local recommended Browning Firearms Service Center. Your Browning Sporting Goods dealer can tell you the address of the Recommended Service Center nearest you or you may call or write our Consumer Information Dept. in Morgan, Utah -(801)543-3200. Otherwise you may return your B-80 to our own repair facility for servicing.
You Are Responsible For Firearms Safety. As a gun owner, you accept a set of demanding responsibilities. How seriously you take these responsibilities can mean the difference between life and death. Failure to follow any of these instructions can cause extensive damage to your gun and/or possible serious injury or death to yourself and others. There is no excuse for careless or abusive handling of any firearm. At all times handle any firearm with intense respect for its power and potential danger.
7. BEWARE OF BARREL OBSTRUCTION. Do this 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 can ruin (swell or rupture) the finest shotgun barrel. BEFORE CHECKING FOR A BARREL OBSTRUCTION, BE CERTAIN YOUR FIREARM IS FULLY UNLOADED. Make sure no live rounds are in the chamber.
12. USE SHELLS OF CORRECT LENGTH. The size of the chamber is inscribed, along with gauge and choke designations, on the side of the barrel. Do not use 31/2" shotgun shells in a shotgun or barrel with a 2 3/4" chamber or 3" chamber. Do not use 3" shells in a shotgun chambered for a 2 3/4" shells. 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. 13.
22. SUPERVISE AND TEACH FIREARMS SAFETY TO ALL MEMBERS OF YOUR FAMILY -ESPECIALLY TO CHILDREN AND NONSHOOTERS. Closely supervise newcomers to the shooting sports. Encourage enrollment in hunting/shooting safety courses. 23. NEVER DRINK ALCOHOLIC BEVERAGES OR TAKE ANY TYPE OF DRUGS BEFORE OR DURING SHOOTING. Your vision and judgment could be dangerously impaired, making your gun handling unsafe to you and to others. 24. PERFORM PERIODIC MAINTENANCE -- AVOID UNAUTHORIZED SERVICING.
