firing, the gas piston system ejects the empty hull from the chamber and
feeds the next shell from the magazine into the chamber, making the
shotgun ready for a following shot. Successive shots can be fired until the
magazine is empty. When the magazine is empty, and the last shell has
been fired, the bolt locks to the rear.
Additionally, a single shell can be inserted manually into the chamber and
the bolt closed, to load the chamber. If the trigger is pulled with the
“safety” in the off safe position, the shotgun will fire the shell. Single-shot
shooting is also possible by loading a single shell into the magazine and
manually cycling the bolt.
6.2. OPERATION
When the trigger is pulled, the firing pin strikes the shell primer, resulting
in the shotgun firing. Gas from the fired shell travels down the barrel and
some is diverted into the gas piston which then sends the piston sleeve
rearward to operate the bolt. During the rearward movement of the bolt,
the empty hull is ejected out of the ejection port. If there is a shell in the
magazine, it is picked up by the bolt as it returns forward by the force of
the recoil spring, and loaded it into the chamber, ready to be fired. If there
is not a shell in the magazine during this movement, the bolt lock engages
and the bolt remains in the open position.
With shells in the magazine and chamber, and the “safety” in the off safe
position, the shotgun will fire a single shell with each successive pull of the
trigger until the magazine and chamber are empty. When the last shell has
been fired, the bolt will lock in the rearmost, open position.
7. INITIAL CLEANING AND LUBRICATION
WEAR EYE PROTECTION WHEN ASSEMBLING AND
DISASSEMBLING YOUR SHOTGUN TO PREVENT SPRINGS,
SPRING-LOADED PARTS, SOLVENTS OR OTHER AGENTS
FROM CONTACTING YOUR EYES, RESULTING IN INJURY.
Various exposed metal parts of this
firearm have been coated at the
factory with a preservative lubricant.
Before using this firearm, a quality
gun oil should be used to clean the
preservative lubricant from the inside
of the action/chamber areas, and the
barrel using a cleaning rod and
patch as explained in Section 23.
Before assembling the firearm you
should first wipe the mechanism
clean and apply a few drops of
quality oil on the indicated surfaces
(Figure 2, page 15). Do not apply too much oil, only a light film is
necessary. Excessive oil should be wiped off, especially in cold weather.
If the firearm is to be stored, it is acceptable to leave the preservative
lubricant on the firearm and keep it in its original packaging. Never shoot
the firearm upon purchase without cleaning it first. If the firearm contains
hardened grease or other substances that you cannot remove, have the
firearm checked by your dealer or departmental armorer. For law
enforcement and military personnel, refer to the procedures of
your department.
8. OPERATION OF THE “SAFETY”
ALWAYS KEEP THE “SAFETY” IN THE ON SAFE POSITION
UNLESS SHOOTING IS IMMINENT. ALWAYS KEEP THE
MUZZLE POINTED IN A SAFE DIRECTION. FAILURE TO
FOLLOW THESE WARNINGS COULD RESULT IN SERIOUS
INJURY OR DEATH.
The cross bolt “safety” is designed to prevent the trigger from being pulled
when in the on safe position. The “safety” is located at the rear of the
trigger guard. In the off safe position, a red warning band is visible on the
FIGURE 2
Apply a few drops of lubricant on the bolt rail
guides and the piston sleeve push rod guide.
