Instruction Manual

HOKE 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. 8b).

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.

Do not use choke values FULL, IMPROVED MODIFIED, and MODIFIED

with slugs, single bullets or single projectiles. Do not use choke value

FULL or IMPROVED MODIFIED with steel shot.

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 the 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.
