Browning 2000 Owners Manual

							right side of the trigger guard. Unlike manyother guns with cross bolt safeties, no extra
parts are necessary for this conversion.
LOADING
BE SURE THE MUZZLE IS POINTED
IN A 
SAFE DIRECTION, AND THE
SAFETY I§ “ON SAFE.” The Browning 
2000 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. Nor is it neces-
sary to insert a round into the magazine and
then cycle the bolt to chamber the first round
After being sure the breech bolt is locked
open, 
all you do is thumb the first round into
the loading port on the left side of the re- 
ceiver.. Push this first round forward so that 
the brass head of the shell is about an 
inch forward of the carrier latch trip (Figure
6). Release the shell by withdrawing your
thumb completely out of the loading port and
letting the shell slam rearward against the 
carrier latch trip. Instantly this round will
be whisked into the chamber ready for firing!
9 
						

							(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 maga- 
zine. This fifth shell (the second shell in line- 
up for firing) is inserted so that it lays in the
loading port with the crimped end protruding only partly into the magazine (Figure 7). Be 
certain that this shell lays straight and is en- 
tirely within the loading port. It is held firm-
ly in this position and will not fall out or
rattle. This is also true when 
the plug is installed
- the third (last) shell to be loaded (second
in  firing sequence) lays visible in the loading
port.
The shell
SWITCH LOADS FAST
which lays visible in the loading
port can be quickly removed, if you want to switch loads in a hurry. Suppose your 2000 is
loaded with duck loads and geese decide to veer 
your way. Simply pluck the visible shell from the loading port and insert a goose load. Cycle
the bolt. Your chambered duck load will eject,
and the goose load will be chambered.
10 
						

							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 succes- 
sive 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 ga.
B-2000 is done with trap, skeet or light field
loads, you may experience a few malfunctions
in the first box or two of shells. After this
short break-in period your B-2000 will oper-
ate well with light or heavy loads.
UNLOADING
As well as speed loading, the Browning
2000 features speed unloading. Before un-
loading, BE SURE THE SAFETY IS “ON SAFE” AND THE MUZZLE IS POINTED
IN A SAFE DIRECTION. The shells in the loading port and maga-
zine are unloaded first. Simply ease the shell 
						

							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 cart-
ridge stop depressed let each shell ride rear-
ward and out of the loading port. In this man-
ner you can remove all the shells except the
one in the chamber. This shell is removed by
drawing the breech bolt rearward and catch-
ing the shell as it ejects.
MAGAZINE PLUG
A magazine plug, restricting the Browning
2000’s capacity to 3 shots, is furnished with
each gun.
TO INSTALL THE PLUG first remove the trig-
ger group (see pages 23 and 24). Merely push
the solid end of the magazine plug through
the opening in the follower until the plug is
MAGAZINE FOLLOWER 
						

							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 trig-
ger 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). Some
pressure with the thumb will be required, since it causes the split rearward end of the
magazine plug to compress and emerge
through the hole in the magazine follower and
into the inside of the first empty shell. Ease
the shells rearward and out of the magazine.
You will now see the plug protruding from
the follower. Simply pull the plug from the 
magazine follower (Figure 9). Now reinstall
the trigger group.
CAPACITY
With the plug removed your 2000 has a
capacity of five 2  3/4 shells. When it is set up
to fire 3 magnum shells with a 3 magnum
barrel, the capacity is four 3 shells.
13 
						

							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” magnumshells.
INTERNAL GAS SYSTEM
The Browning 2000 has a uniquely de-
signed, 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.
The gas is sealed off so that it cannot
blow rearward into the forearm, along the 
action bar assembly and toward the action 
The gas is vented forward through the hole
in the forearm cap.
How often should you strip down the gas
system and clean it? There is no rule of 
thumb. It depends somewhat on the type of
ammunition you use and how heavily you
shoot your gun. Hunters will probably want to
clean the system at the season’s end. Trap
and skeet shooters will perhaps want to clean
it more frequently It’s a matter of shooting
conditions and judgment.
DISMANTLING AND CLEANING THE
GAS SYSTEM
Dismantling the gas system is very simple.
Make sure the safety is on and draw the
breech bolt rearward until it locks open. Un-
screw the forearm cap and remove the barrel
and forearm.
You will notice the gas piston bar project-
14 
						

							ing from each side of the magazine tube (Fig-
ure 12). Remove this simply by pushing it
