load in the chamber of the gun without going to
the trouble of unloading the whole magazine. For
instance, in this way a duck load can quickly be taken
out and a goose load inserted, if the need arises.
To operate the magazine cutoff, merely manipulate 
the lever to the “MC” or “R” positions. The “MC”

WEAR EYE PROTECTION WHEN PERFORMING
ANY MAINTENANCE OR DISASSEMBLY
REMOVING THE TRIGGER GROUP - You will
need two medium blade screwdrivers to remove
the trigger guard retaining screws (the trigger
guard retaining nut and the trigger guard
retaining screw). Make sure the screwdrivers are
of appropriate size to prevent damage to the
slotted heads. No other tools are necessary.
1Remove the barrel as explained under
“Disassembly . . . ”on page 21. Set the
forearm,...

turning while unscrewing the opposite side
(See Figure 9).
Remove the retaining nut and screw from
the receiver.
With the gun inverted (trigger guard up),
grasp the trigger guard and pull it up,
forward and out from the receiver (See
Figure 10). DO NOT DISASSEMBLE THE
TRIGGER GROUP BEYOND  THIS POINT
Perform all cleaning with the trigger group
kept intact as an assembly
REMOVING THE BREECHBLOCK - Normal
procedure is to remove the trigger group first, as
explained previously. 

12Remove the operating handle as follows:
With your left hand, push on the bolt head
moving the breechblock about 
1/2 back
into the receiver, lining up the operating
handle with the notch at the bottom front
of the ejection port (See Figure ll-A). With
your right hand grasp the operating handle
and pull it outward, removing it from the
breechblock (See Figure ll-B).
The breechblock will now be able to move
forward about another 1/2. Again, push
rearward on the bolt head, depressing the
breechblock back...

found on the bottom side of the breechblock
(See Figure 12). The breechblock lever serves
to retain the breechblock in the receiver.
(SPECIAL NOTE: It is possible to remove
the breechblock first before removing the
trigger group. You will need simultaneously
push rearward 1/4 on the breechblock
and “reach” in through the opening at the
front of the carrier to depress the
breechblock lever, using the eraser end of
a pencil, a small wood dowel, a
screwdriver, or other similar object.)
With the breechblock...

the breechblock must fit in the receiver tracks.
Make sure the front action springs fit over
the ends of the action spring guides (See
Figure 13). Push the breechblock in far
enough that the breechblock lever engages,
holding the breechblock in the receiver.
Simultaneously push back on the breechblock
while depressing the breechblock release
button until the notch in the ejection port
lines up with the operating handle recess
on the breechblock. Make sure that the
action springs are compressed inside...
