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.
PLEASE READ AND UNDERSTAND ALL OF THE PROPER HANDLING AND INSTRUCTION PROCEDURES OUTLINED IN THIS BOOKLET BEFORE USING YOUR NEW FIREARM. ALWAYS KEEP THE MUZZLE OF YOUR SHOTGUN POINTED IN A SAFE DIRECTION even though you are certain

the shotgun is unloaded. Never point your shotgun at anything you do not intend to shoot. Be extremely alert and aware of all persons and property within the range of your ammunition.

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.\” Like any mechanical device, a safety can sometimes fail; it can be jarred or inadvertently manipulated into an unsafe condition. Mechanical \”safeties\” merely aid safe gun handling and are no excuse for pointing your shotgun\’s muzzle in an unsafe direction. While it is a good idea to \”test\” your shotgun\’s mechanical \”safety\” periodically for proper function, NEVER TEST IT

NEVER TRUST YOUR SHOTGUN\’S MECHANICAL \”SAFETY\” DEVICE.

WHILE YOUR SHOTGUN IS WADED OR POINTED IN AN UNSAFE DIRECTION.

Safe gun handling does not stop with your gun\’s mechanical \”safety\” device — it starts there. Always treat this shotgun with the respect due a loaded, ready-to-fire firearm. 3

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.
DO NOT TRANSPORT YOUR SHOTGUN LOADED, WHETHER IN A SCABBARD, GUN CASE, OR OTHER CONTAINER. BEWARE OF BARREL OBSTRUCTIONS–

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 ruin (swell or rupture) the finest of shotgun barrels. Before you load your firearm, open the action. BE CERTAIN NO LIVE ROUND IS IN THE CHAMBER. Then look through

4

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. Store your gun and ammunition the separately-beyond reach of children. Take all safeguards to ensure your gun does not become available to untrained, inexperienced, or unwelcome hands.

The barrel and action of this shotgun have been made with substantial safety margins over the pressures developed by established American commercial loads. Nevertheless, Browning assumes no liability for accidents which occur through the use of cartridges of non-standard dimensions or which develop pressures in excess of commercially available ammunition which has been

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

The most certain way to bulge or rupture a barrel is to drop a 20 gauge shell into a 12 gauge chamber. The 20 gauge shell, unfortunately, will not fall completely through the barrel; its rim is caught by the front of a 12 gauge chamber. Your gun will misfire. It is then possible to load a 12 gauge shell behind the 20 gauge shell. If the 12 gauge shell is then fired, the result will be a so-called \”12-20 burst\” which can cause extensive damage to your gun and possible serious injury to you.
DO NOT USE 3\” SHOTGUN SHELLS IN A BARREL WITH A 2 3/4\” CHAMBER. THE SIZE OF THE CHAMBER IS INSCRIBED, ALONG WITH CHOKE DESIGNATIONS, ON THE SIDE OF THE BARREL.

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.

ALWAYS UNLOAD ANY GUN\’S CHAMBER AND MAGAZINE BEFORE CROSSING A FENCE, CLIMBING A TREE, JUMPING A DITCH OR NEGOTIATING OTHER OBSTACLES.

Refer to page 30 of this instruction booklet for instructions on the unloading of your shotgun. Never lean a loaded gun against a fence, tree, car or other similar object.
WEAR EYE AND EAR PROTECTION WHEN SHOOTING. Unprotected, repeated

exposure to gunfire can cause hearing

7

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. Be extremely careful, while hunting or during any shooting activity, to avoid dropping a loaded firearm.

IF YOUR GUN FAILS TO FIRE, KEEP THE MUZZLE POINTED IN A SAFE DIRECTION. Hold this position for a

minimum of 30 seconds. Carefully open the action and remove the cartridge. If the primer is indented, the cartridge should be disposed of in a way that cannot cause harm. If the primer is not indented, your firearm should be examined by a qualified gunsmith and the cause of the malfunction should be corrected before further use.

BE DEFENSIVE. BE ON GUARD AGAINST UNSAFE GUN HANDLING AROUND YOU AND OTHERS. Don\’t be

8

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.

EDUCATE AND SUPERVISE FIREARMS SAFETY TO ALL MEMBERS OF YOUR FAMILY, especially to children and non-

shooters. Closely supervise newcomers to the shooting sports. Encourage enrollment in hunting/shooting safety courses.

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 or to others.

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

Your gun is a mechanical device and is subject to wear and requires periodic inspection, adjustment, and service. Browning firearms should be serviced by a Browning Recommended Service Center or by Browning\’s service facility in Arnold, Missouri. Browning cannot assume any responsibility for injuries suffered or caused by unauthorized servicing, alterations or modifications of Browning firearms. IT
CAN BE VERY DANGEROUS To ALTER THE TRIGGER OR OTHER FIRING MECHANISM PARTS OF ANY FIREARM.

PERIODIC MAINTENANCE– UNAUTHORIZED SERVICING.

BE CAREFUL!

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.

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. However, Browning can assume no responsibility for incidents which occur through the use of cartridges of non-standard dimension or those developing pressures in excess of SAAMI (Sporting Arms and Ammunition Manufacturer\’s Institute) established standards.
CAUTION: DO NOT USE 3\” SHOTGUN SHELLS IN A BARREL WITH A 2 3/4\” CHAMBER. THE SIZE OF THE CHAMBER IS INSCRIBED, ALONG WITH CHOKE DESIGNATIONS, ON THE SIDE OF THE BARREL.

With the E80 Plus barrels are inscribed 3\” and 2 3/4\”. The E80 Plus barrel is designed to accept either sized shell. 12

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. To close the bolt, depress the cartridge stop / bolt release button which is located just below the ejection port on the right side of the receiver. (See Figure 2.)

13

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.

CAUTION: KEEP YOUR FINGERS CLEAR OF THE EJECTION PORT AS THE BOLT CLOSES.

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. The various exposed metal parts of 14

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\”. All B-80 Plus models require a recoil adapter as described below. You may have to install a recoil adapter in your pre \’87 12 gauge B-80. If you are going to use a 2 3/4\” barrel, note the area where the magazine tube enters the receiver. If there is a thin spacer (recoil adapter) between the two forearm guide screws and the receiver, your B-80 shotgun is ready for a 2 3/4\” barrel and 2 3/4\” loads. (See Figure 4.)

15

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. Your dealer can install this adapter or, you may install it yourself by referring to this instruction booklet in the following manner: 16

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. When completed with step seven on page 42, your B-80 is ready to function with 2 3/4\” light target loads. REMEMBER: When you plan on installing a 3\” magnum barrel to shoot 3\” shells, you should remove the recoil adapter. As mentioned previously, the recoil adapter described above needs to be used only on those B-80s manufactured prior to late 1985.

17

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.) While holding your B-80 upright, note the position of the gas piston which is held in position by the forearm and forearm cap
