oil the threads inside the barrel, as well as on the choke
tube itself. This will protect the threads from being
damaged, and also prevent dirt build up that would
cause the choke tube to become difficult to remove
from the barrel. Clean the threads with solvent and a
small, soft brush like a toothbrush. Wipe completely
clean and leave a thin film of clean oil on the threads
— both on the tube and in the barrel. The threads of
the choke tube and the internal threads of the barrel
should be cleaned after each use and before the
installation of a tube.
3. Be careful when removing or installing a tube. Use the
specially designed WinChoke spanner wrench. Damage
can result to both the choke tube and the barrel when
attempting to remove sticky choke tubes.
4. Never fire your shotgun or run cleaning tools through
the barrel of any choke-tubed gun without having a
choke tube installed.
R EMOVING THE M AGAZINE P LUG
When hunting migratory birds, Federal Law mandates the
use of a magazine restriction device that only allows a total
of three shells to be held in your shotgun at one time.
WHEN REMOVING THE PLUG BE CERTAIN THERE ARE NO
SHELLS IN THE MAGAZINE OR CHAMBER, AND KEEP THE
BARREL AND MAGAZINE POINTED IN A SAFE DIRECTION
AT ALL TIMES. REMEMBER, THE PLUG IS UNDER SPRING
PRESSURE SO CARE MUST BE TAKEN FOR SAFE
REMOVAL. ALWAYS POINT THE END OF THE MAGAZINE
AWAY FROM YOUR FACE AND IN A SAFE DIRECTION.
ALWAYS WEAR EYE PROTECTION WHEN REMOVING AND
REINSTALLING THE MAGAZINE’S THREE-SHOT PLUG.
The magazine plug is spring-loaded and can thrust out of
the magazine when the friction-type magazine retainer is
removed too quickly. Never look directly into the cap end
of the open magazine.
1. Remove the magazine cap.
2. Place one hand over the retainer and pry it up slowly
with a screw driver using your other hand (Figure 9).
When the retainer releases you will feel the pressure of
the friction ring and plug on the palm of your hand.
