2Open the action and place the “safety” in
the “on safe” position.
3Before installing a tube, check the internal
choke tube threads in the muzzle, as well
as the threads on the Invector choke tube
to be sure they are clean. Lightly oil the
threads with an oil like Browning Oil.
4Using your fingers screw the appropriate
tube into the muzzle end of the barrel,
tapered end first, notched end outward. When
it becomes finger-tight, use the Invector
choke wrench to firmly seat the tube.

or use the identification mark(s) located on the
top rim of each tube (See Figure 20).
INVECTOR TUBE SELECTION
This chart shows lead/steel choke constriction
designations for each lnvector tube within each
gauge. Designation is listed lead first, then steel:
for example, M/F means a certain tube shoots
Modified with lead shot and Full with steel shot.
Tubes listed are also available as accessories.

Use of Extra Barrels
On all Browning A-500 shotguns, barrels of the
same gauge are completely interchangeable, and
no special fitting is required. Thus, by merely
buying another barrel of a different length, or
for a different purpose (such as a Buck Special
barrel), and using the appropriate lnvector choke
tube, you have acquired the utility of another
gun at a traction of the cost of a new gun; a
duck gun becomes a fine upland game gun, a
pheasant gun becomes a rifled slug deer gun.
Sight Adjustment...

VERTICAL ADJUSTMENT - Adjustment of the
sight is controlled by the screw located on top of
the sight. To RAISE the point of impact, turn the
screw in a counterclockwise direction. To
LOWER the point of impact, turn the screw in a
clockwise direction. Vertical adjustment is also a
process of trial and error.
Cleaning and Maintenance
Suggestions
You should clean your A-500 whenever it becomes
excessively dirty - and perform a thorough
cleaning at least once a year. The barrel should
be cleaned, and the...

PERIODIC OILING- Ordinary good judgment
will indicate that the metal parts of the gun
should receive a light film of oil after the gun
has been exposed to weather or handling.
Occasionally, a small drop of oil may be placed
on each receiver track in which the barrel
extension guides and breechblock run during
operation (See Figure 21). This will help to
relieve friction and ensure smooth operation.
Also, lightly lubricate the breechblock, rotary
bolt and spring guides. DO NOT POUR LARGE
QUANTITIES OF OIL...

CLEANING PROCEDURES - The correct pro-
cedure for cleaning your A-500 shotgun is as follows:
BE CERTAIN YOUR SHOTGUNS
MAGAZINE, FEED MECHANISM AND
CHAMBER ARE UNLOADED. PLACE
THE “SAFETY” IN THE “ON SAFE”
POSITION. ALWAYS WEAR
PROTECTIVE SAFETY GLASSES
DURING ALL DISASSEMBLY AND
CLEANING PROCEDURES.
Remove the barrel so that it can be
cleaned from the breech end (See
“Disassembly . . . ” on page 21).
Using a shotgun cleaning rod with tip and
patch large enough for a snug fit in the
bore, insert the rod...

5A normal amount of leading can be
expected with today’s high velocity loads
and improved wads but this is not serious.
If or when leading should become heavy, it
can be removed with a brass bore brush.
Make sure a choke tube is installed. Spray
the bore or the bore brush with a good
powder solvent, and scrub the bore until
leading is removed. To prevent brass
bristles from breaking off, the brush should
be pushed completely through the bore
before being withdrawn.
6After leading has been removed, the...

explained under “Full Disassembly . . . ” on
page 31. Clean with an oil such as Browning
Oil or a gun solvent as necessary, using an old
toothbrush to loosen any caked-on grime.
Wipe the receiver cavity clean. Lightly oil
the cavity (aerosol Browning Oil is ideal)
and wipe it dry. No further disassembly is 
required for cleaning.
Reassemble the trigger group, breechblock,
and the barrel to the receiver. Then wipe all
exposed metal surfaces with an oiled cloth
making sure to wipe your A-500 clean of all...
