ZAFER-CHOKE® screw-in choke tubes are made of
high-grade steel for corrosion resistance and
durability with special heat treatment. ZAFER Over &
Under Shotgun is supplied together with 5 ZAFER-CHOKE®
choke tubes. These chokes have 1 notch to 5 notches
in their top rim for different purposes. All ZAFER-CHOKE®
tubes are designed for use with factory cartridges
loaded to standard specifications.
ZAFER-CHOKE® tubes are also inscribed on the
side with the patterns F, IM, M, IC, CL they produce
with lead shot. ZAFER-CHOKE® tubes are fully
interchangeable. You can use them with other ZAFER
products.
ZAFER-CHOKE® is a registered trademark of
ZAFER ARMS COMPANY.
WARNING: DO NOT USE ZAFER-CHOKE® TUBES IN ANY
SHOTGUN BARRELS NOT SUPPLIED BY ZAFER. ALSO, DO NOT
USE ANY OTHER CHOKING DEVICE IN ANY SHOTGUN BARRELS
SUPPLIED BY ZAFER.

ZAFER-CHOKE® CODES (DEFINITION) |
To identify ZAFER-CHOKE® tubes, use the
identification mark(s) located on the top rim of
each tube. These notches are a code to allow you to
determine the choke designation while the tube is
installed.

ZAFER-CHOKE® TUBE SELECTION |
To help you choose the correct choke tube for each
hunting situation, all ZAFER-CHOKE® tubes are
inscribed on the side with the patterns they produce
with lead shot. The notches on the rim and pattern
designation on the side are only for lead shot. For
steel shot you will need to use the cart below to
cross-reference from lead to steel and determine
appropriate tubes for your ammunition and hunting/shooting
situation. Since steel shot generally patterns
tighter than conventional lead shot loads, it would
be wise to avoid the use of steel shot altogether in
conventionally choked "FULL CHOKE" barrels. "MODIFIED
CHOKE" barrels generally deliver "FULL CHOKE"
patterns when used with steel shot.
WARNING: Whenever handling any shotgun for the
purpose of removing or installing a choking device,
make absolutely certain the gun is fully unloaded,
and the action is open. Never attempt to remove or
install a shotgun choking device on a loaded firearm.

INSTALLATION OF CHOKE TUBES |
WARNING:
Check the firearm is unloaded. If not, unload the
firearm by operating as described in the chapter "Unloading
the shotgun".
WARNING: Never look into the muzzle or change tubes
on a loaded gun, even with safety engaged.
1. Either open the action or lift the barrel out of
the receiver.
2. Apply a thin coat of gun oil to the threads of
the barrels and of the choke tubes.
3. Insert the desired chokes into the choke housings.
4. Carefully hand screw the chokes into the barrels
clockwise. Using the ZAFER choke tube wrench tighten
the chokes until they are fully bottomed into their
recesses in the barrels.
5. Remove the choke tube wrench after tightening.

WARNINGS
|
1. Never shoot choke barrels without using choke
tubes. Shooting without choke tubes is very
dangerous as debris could be trapped by the threads
and create barrel obstructions. This situation is
very dangerous when firing and may cause damage to
the shotgun and serious injury to the shooter and
bystanders. It may also cause erratic shot pattern
and can damage the barrel's internal screw thread
irreparably.
2. Choke tubes must be kept correctly tightened in
the barrels at all times, even during storage and
cleaning. Cleaning barrels with no choke tubes in
place can push dirt into the barrel threads, causing
improper choke installation, rusting, or barrel
obstruction.
3. Periodically check, with the unloaded and opened
chambers, whether the chokes are fully and tightly
set into the barrel. If necessary, firmly tighten
the chokes, using the ZAFER choke tube wrench, until
they can be tighten no more. This tightening is
needed to avoid damage to the barrels and to avoid
propelling the chokes out of the muzzle when the gun
is fired, which may cause damage to the gun or
injury to persons.
