kinking the front action springs.
Insert the operating handle into the recess
(See Figure 11-A on page 37). The
breechblock is now installed.
REINSTALLING THE TRIGGER GROUP -
Reinsert the trigger group into the bottom
of the receiver, moving it rearward to
assure correct location of the rear pins into
the holes in the receiver. Then start at the
back and hinge the trigger guard forward
(See Figure 14).

							Line up the hole in the trigger guard with
the holes on each side of the receiver.
Insert the trigger guard retaining nut
completely through the receiver. Start the
retaining screw with your fingers and tighten
using two screwdrivers, one for each
slotted head on each side of the receiver.
Three-Shot Magazine Adapter
The following instructions are for disassembly of
the magazine, and the removal or installation of 
the three-shot magazine adapter. Steps 
1-8 detail
magazine disassembly, and are the same for 
both removal and installation of the three-shot
adapter. Steps 9-A and 9-B explain reassembly of
the magazine with or without the  three shot adapter.
The A-500 shotgun is delivered with the three-
shot magazine adapter installed in the magazine,
limiting magazine capacity to two shells -
allowing three shots total in compliance with
federal migratory bird regulations. If you do not
wish to be limited to three shots - when it is
not required by law 
- you can remove or
reinstall the three-shot adapter (plug) as follows:
ALWAYS WEAR PROTECTIVE SAFETY
GLASSES DURING THIS OPERATION.

							Unscrew the forearm cap and remove the
forearm, BARREL, forearm buffer and recoil
spring from the gun as explained under
“Disassembly of Barrel and Forearm
Assembly” on page 21.  UNDER NO CIRCUM-
STANCES SHOULD YOU PERFORM THE
FOLLOWING PROCEDURES  
WITH THE
BARREL ATTACHED.
2Reinstall the magazine cap on the magazine
tube approximately one turn engaging at
least ONE FULL  TURN OF THREADS  solidly.
3Release the breechblock forward slowly by
pressing the breechblock release button and
slowly allowing the breechblock to travel
forward. Do this by pressing the button with
one hand and offering resistance on the oper-
ating handle with the other hand, gently
easing it forward to the fully forward position.
4Pull back approximately 1/4 of an inch
on the operating handle. With your other
hand insert two 2 3/4 (or two 3-inch
magnum shells) into the magazine if you
are removing the three-shot adapter OR
insert four 2 3/4 shells (or three 3-inch
magnums) if the three-shot adapter was 
removed previously and you are
reinstalling it. Position an additional shell
as if you were going to insert it into the
43 
						

							magazine (it will stop only partially
inserted because of the full magazine).
Apply steady, hard pressure on the shell,
pushing all the shells forward in the magazine
until the magazine spring retainer is
dislodged from its compressed fitting at the
end of the magazine (See Figure 15). You
will feel forward movement of the shells in
the magazine when it is dislodged.
IF IT WILL NOT DISLODGE WITH
STEADY PRESSURE  you may have to
work the last shell in and out to increase
force on the shells in the magazine.
If this also fails to dislodge the magazine spring
retainer, place another shell behind the one 
						

							partially inserted and apply increased 
pressure with the palm of your hand, or
strike the back of the last shell with thepalm of your hand until the retainer is
dislodged (See Figure 16).
NOT USE ANY OTHER OBJECT THAN
THE PALM OF YOUR HAND TO APPLY
PRESSURE TO THE LAST SHELL.
With the retainer dislodged,  IMMEDIATELY
REMOVE THE SHELLS FROM THE
MAGAZINE. DO NOT UNSCREW THE
MAGAZINE CAP WITH SHELLS IN THE
MAGAZINE. Remove the shells by first
pulling back approximately 1/4 on the
operating handle. Then release the shells 
from the magazine by reaching inside the
45 
						

							loading port and simultaneously pressing
in on the bottom of the carrier and
pressing the carrier latch with your finger
(See Figure 17). Release and remove one
shell at a time from the magazine.
IMMEDIATELY PUT ALL THE SHELLS
AWAY IN YOUR AMMUNITION
STORAGE AREA  - AWAY FROM  YOUR
A-500 AND OTHER GUNS.

Carefully unscrew the magazine cap from
the magazine. CAUTION: THE MAGAZINE
SPRING IS UNDER TENSION AND WILL
FORCE OUT THE RETAINER, THREE
SHOT ADAPTER AND THE SPRING
ITSELF UNLESS CARE IS TAKEN.  Slowly 
						

							lift the magazine cap off of the magazine.
At the same time, catch the spring with
your other hand as it begins to come out
(See Figure 18). If already installed, the
three shot adapter will be on top of the
magazine spring.
Remove the spring and adapter, if present,
from the magazine tube. Remove the 
magazine spring retainer from the inside of
the magazine cap. The magazine follower
can be removed by pointing the magazine
tube downward and dumping it out.
REASSEMBLY WITH THE THREE-SHOT
MAGAZINE ADAPTER INSTALLED
To reassemble the magazine with the
47 
						

							three-shot adapter installed, first, position
the gun vertically, butt down. Then
reinstall the magazine follower in the
magazine tube, closed end first. Place the
three-shot adapter inside one end of the
magazine spring, small end first. Place the
magazine spring retainer over the top of
the adapter. Insert the other end of the
magazine spring into the magazine tube
and compress it into the magazine tube
(See Figure 19). With hand pressure, seat
the magazine spring retainer fully into the
compression fitting on the end of the
magazine tube.
48 
						

							REASSEMBLY WITHOUT THE THREE-
SHOT  MAGAZINE ADAPTER.
Reassembly of the magazine without the
three-shot adapter is identical to step 9-A
with one exception: after inserting the
magazine follower into the magazine tube,
place the magazine spring retainer directly
on the end of the magazine spring. Then 
insert the other end of the magazine spring
into the magazine tube and compress it into
the magazine tube. With hand pressure,
seat the magazine spring retainer fully into
the compression fitting on the end of the
magazine tube.
Reassembly of the magazine, and removal/
installation of the three-shot magazine adapter is
now completed. To prepare for replacing the
barrel and forearm on your A-500, pull the
operating handle on the breechblock fully
rearward, locking the breechblock back. You are
now ready to reinstall the barrel/forearm
assembly to the receiver as outlined in
“Assembly Procedures-Barrel to Receiver” on
page 16.

							Invector Interchangeable Choke
System
All A-500 shotgun barrels have been threaded to
accept the Browning Invector Interchangeable
Choke System. You may confirm this by looking
on the right side of your barrel where the
specifications are inscribed, and where the
choke markings are normally located. The word
INVECTOR denotes that the barrels are
threaded. The degree of choke tube is indicated
twice on each choke tube: Inscribed on the side
of the tube, and indicated with a “notch’ code
on the top rim of the tube.
Invector Choke Tubes are made with tempered
steel and are fully compatible with all FACTORY
AMMUNITION (loaded in compliance with 
SAAMI specifications) including Magnum lead
and steel shot loads and rifled slug loads.
