GAS OPERATED AUTOMATIC SHOTGUN NOMENCLATURE In conventional gun terminology, the position and movement of gun parts are described as they occur with the gun horizontal, in normal firing position; i.e., the muzzle is forward or front; butt stock is rearward or rear; trigger is underneath; the rib is on top. CAUTION a. A L W A Y S V I S U A L L Y C H E C K YOUR SHOTGUN - to be certain that it does not inadvertently contain any ammunition.
and with alert consideration to all within its range. c. ALWAYS KEEP THE MUZZLE OF YOUR GUN POINTED IN A SAFE DIRECTION - even though you are certain the gun is unloaded and “on safe.” Never point your gun at anything you do not intend to shoot. d. ALWAYS UNLOAD YOUR SHOTGUN WHEN NOT IN USE - As a safety precaution it is preferable to disassemble your gun for storage. Store your gun and ammunition separately - beyond the reach of children. e.
ed a more serious hazard to your gun and yourself. f. 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. g. 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.
CAUTION: Do not take the measurement of an unfired shell to determine the length. An unfired 2 3/4" shell, for example, only measures about 2 1/2". Most shell boxes are stamped as to the length of the shells they contain and some shells are actually individually marked as to their length. The Browning 2000 must be used only with the gauge of ammunition stamped on the barrel.
MOUNTING THE BARREL TO ACTION Your Browning 2000 is packaged and shipped with the forearm attached to the receiver and magazine tube. In order to install the barrel it is necessary to remove the forearm from the magazine tube and affix the forearm on the barrel before mounting the barrel to the action. Follow the stens below: 1. THOROUGHLY CLEAN ALL ANTIRUST COMPOUND FROM THE BARREL,THE BORE AND OTHER METAL SURFACES. Remove with any good quality gun oil or gun cleaning solvent. 2.
4. Draw the breech bolt rearward so that it remains locked back. Be sure the safety is “on safe”. 5. Grasp the butt stock by the pistol grip and anchor the butt end on your hip. With your other hand grasp the forearm and barrel and after a final glance through the bore to be sure there is no barrel obstruction, carefully work the forearm down the magazine tube and introduce the barrel extension into the receiver (Figure 2).
6. As the barrel and forearm are seated into final position, be certain the Ushaped cut in the barrel extension (Figure 3) mates fully against the Fig. 3 barrel guide in the upper inside of the receiver (Point A, Figure 4). Also check that the metal forearm tabs in the rearward end of the forearm (Figure 5) slide into the opposing receiver recesses (Point B, Figure 4). 7. Screw the forearm cap onto the magazine tube. HAND TIGHTEN ONLY.
Never apply a wrench or any kind of severe force. Removing the barrel is simply done by reversing the above procedure. If you prefer to store your gun with the action and barrel separated, it is suggested that the forearm be attached to the magazine tube and receiver. This secures your forearm and prevents it from possible damage. CLOSING THE BREECH Do not press the carrier latch and let the breech bolt ride home under its own force, unless the bolt is actually feeding a round into the chamber.
right side of the trigger guard. Unlike many other guns with cross bolt safeties, no extra parts are necessary for this conversion. LOADING BE SURE THE MUZZLE IS POINTED IN A SAFE D I R E C T I O N , A N D T H E SAFETY I§ “ON SAFE.” The Browning 2 0 0 0 is equipped with the speed loading system Browning Automatic shotguns are famous for. It is not necessary to jiggle the first round into the chamber and then trip the carrier latch (bolt release) to ready the first round for firing.
(Remember to keep your fingers away from the ejection port on the opposite side of the receiver. The bolt drives forward with force during the loading of this first round.) The second, third and fourth shells to be loaded are then thumbed completely into the magazine. You will not be able to insert the fifth shell you load completely into the magazine.
FIRING Once loaded, all that is necessary to fire the gun, of course, is to push the safety to the “fire” position and pull the trigger. The first shell will fire and be ejected. The second will automatically be chambered. The trigger must be released and pulled to fire each successive shot. THE BREECH REMAINS OPEN after the last shot has been fired. This allows you to reload quickly, if you desire to. BREAKING IN WITH LIGHT LOADS If the initial shooting of your 12 g a .
in the loading port outward with your thumb until you can remove it. To remove the shells in the magazine depress the cartridge stop. The cartridge stop (Figure 8) projects from the bottom of the bolt slide. With the cartridge stop depressed let each shell ride rearward and out of the loading port. In this manner you can remove all the shells except the one in the chamber. This shell is removed by drawing the breech bolt rearward and catching the shell as it ejects.
completely within the magazine (Figure 9). Important: Be certain that the split end of the magazine plug is rearward. TO REMOVE THE PLUG first remove the trigger group (see pages 23 and 24). Then take an empty shotshell and place the mouth of the shell against the magazine follower (Figure 10). Thumb this empty shell far enough into the magazine to place a second empty shell behind the first. Then press the second empty shell into the magazine (Figure 11).
With the plug installed the capacity is reduced to three shells - whether the 2000 is set up to fire 2 3/4" shells only or 3” magnum shells. INTERNAL GAS SYSTEM The Browning 2000 has a uniquely designed, extremely reliable gas system. It is compactly contained within the magazine tube. This makes it less accessible to dirt and allows a slim forearm design.

This is necessary because the gas system is under spring tension. Now ease the gas system components forward out of the magazine tube.

CAUTION: Do not trip the carrier latch and let the bolt fly home when the gas piston bar is removed. The operating handle of the bolt will slam into the front of the receiver and damage it. If you wish to close the bolt at this time, make sure you hold onto the operating handle and let the bolt very slowly ride forward until the operating handle rests against the forward edge of the ejection port. You are now ready to wipe out the magazine tube and clean the components.
particular attention to lining up the slot in the gas piston bar guide (A, Figure 15) with the holes in the gas piston (B, Figure 15) and the magazine tube (C, Figure 15) so that you can easily insert the gas piston bar. Be cer- tain that the slot in the gas piston bar guide (A, Figure 15) is rearward. This is critical for proper functioning.

of the receiver. DO NOT LET THE BOLT SLAM FORWARD. 3. Remove the trigger guard retaining pin (Figure 17). Fig. 17 TRIGGER GUARD RETAINING PIN 4. Draw the bolt rearward about 11/2 inches (Figure 18).
5. With your other hand trip the carrier latch, grasp the trigger guard (Figure 18) and remove by forcing it slightly forward before attempting to lift it out of the receiver (Figure 19). Ease the bolt forward again. With the butt stock resting firmly on a workbench or table, grasp the action bar assembly and compress the a c t i o n spring several inches (Figure 20). Remove the bolt operating handle with your other hand.
pressure removes it easily (Figure 21). 9. To remove the bolt and bolt slide ease the action bar assembly forward off the magazine tube while depressing the cartridge stop with your finger (Figure 22). The cartridge stop projects from the bottom of the bolt slide. Particularly notice how the double action bars separate from the bolt. This will help you during reassembly later.
You can now easily clean all of these components as well as the inside of the receiver. (See Figure 23.) Again a good solvent is ACTION SPRING BOLT S L I D E CARTRIDGE STOP recommended. Further disassembly of the trigger group is not recommended. NOTE: Do not apply large quantities of oil to the trigger group or other areas of the action. Excessive oil is not necessary and serves to collect dust and minute particles of dirt.
recesses in the bolt slide. This is done just forward of the receiver before the bolt is completely inserted into the receiver. Notice that the left (loading port side) action bar enters from the top of the bolt slide (Figure 24) while the right action bar LEFT A C T I O N BAR E N T E R S BOLT SLIDE FROM TOP attaches from the bottom (Figure 25). It is RIGHT ACTION BAR ENTERS BOLT SLIDE FROM BOTTOM Fig.
easiest to cant the bolt assembly to the left and attach the left action bar first, then rotate the bolt assembly to the right and downward until the right action bar is engaged. 3. Keeping the action bars located in the bolt slide with your fingers (Figure 26) carefully orient the bolt assembly in the appropriate receiver channels and push rearward on the action bar assembly until the bolt assembly slides into the receiver.

STOP stop. (This is the long, slender, unblued piece of metal which lies alongside the carrier; see Figure 27.) If you will tip the trigger group so that you introduce the carrier and the carrier cartridge stop into the receiver first, you can easily avoid scratching the receiver. 6. Lock the bolt open. 7. Replace the gas system (see pages 19 and 20) and install barrel and forearm.
NOTE: As pointed out earlier, you do not need a complete separate gun to shoot 3” magnums. An extra 3” magnum barrel is all that is needed. Simply interchange barrels. Altering the gas system is unnecessary. See page 22. NOTE: With the 3 inch Magnum barrel installed the B-2000 is designed to function reliably with 3 inch Magnum shells.
3. Inspect bore from both ends for leading by looking through bore toward light. Leading will appear as dull longitudinal streaks and is usually more predominant in the constriction area of the choke and just forward of the chamber. 4. Leading is minimal with today’s modern loads. If or when leading should become heavy, it can be removed with a brass bore brush. Use a good powder solvent such as Browning Liquid Gunsmith and scrub bore until leading is removed.
SERIAL NUMBER: The serial number of your Browning 2000 Shotgun is found on the underside of the receiver, just forward of the carrier. CHOKE MARKING The choke of your barrel is indicated by a clearly defined mark stamped on the right hand side of the barrel.
