CHOKE TUBES
BEFORE REMOVING OR INSTALLING ANY CHOKE TUBE:
Move the safety button fully rearward to the “ON” (SAFE) position (Fig. 1)
and keep the muzzle pointed in a safe direction.
Open the firearm, visually and physically check both chambers to be
certain the firearm is unloaded (Fig. 7).
Do not use bent or deformed choke tubes as these may result in tube or
barrel damage upon firing which may cause serious personal injury.
Inspect choke tubes periodically to insure they are properly installed and
in good condition. Pay special attention to the threaded end of the choke
tube to be certain it is not deformed or dented.
Never fire this shotgun without a choke tube properly installed. Failure to
do so will damage the precision threads on the inside of the barrel. Firing
this shotgun with loose choke tubes may lead to damage to the choke
tube and barrel, as well as serious personal injury.
CARE & CLEANING: The precision threads on your choke tube should be kept
clean and lightly oiled at all times.
During cleaning of the barrel, be certain the choke tube is properly installed. This
will avoid residue build-up on the threads.
Mossberg International choke tubes shipped with the firearm are designed for use
with Lead, Steel, and other non-toxic shot. Each tube is marked with the type of
pattern it will produce.
TO REMOVE CHOKE TUBE: Loosen with choke wrench provided, turning it
counterclockwise. When the choke tube is loosened, remove it completely with
your fingers. Place choke tube on a clean, dry surface.
TO INSTALL CHOKE TUBE: Screw the tube clockwise into barrel by hand and
then tighten the tube until snug with the choke wrench. These tubes fit
completely inside the barrel when properly installed. Do not use excessive force
when installing.
Tube tightness should be checked periodically.
