ACCESSORIES AND ADJUSTMENTS
Drop and cast adjustment
Before beginning any operation on your shot-
gun, always make sure that chamber and
magazine have been completely emptied!
(Carefully read loading and unloading instruc-
tions).
The shotgun is supplied with a “drop change kit”
(fig. 56) which enables you to adjust the original
drop the shotgun is supplied with.
The kit includes steel stock locking plates and
plastic drop change shims in addition to a pin for
fitting a sling attachment (for wooden stocks).
The kit enables you to obtain five different drop
patterns (as specified in the table) and two different
deflections (right hand or left hand). Each unit is
marked with the corresponding drop and cast
letter.
Determine if your stock drop fits you perfectly, or
whether it is either too high or too low for you.
If the stock is too low for you (meaning that the
drop is too great), select the adjustment set in
reverse alphabetic order (e.g. if the shim fitted in
the factory is marked “C”, switch to that marked
“B” and to the corresponding stock locking
plate).
Proceed as follows to change shims (fig. 57).
1) Unscrew the two fixing screws and remove
the butt plate “1” (using a cross-head screw-
driver).
WARNING: to avoid damaging the butt plates,
apply a light coat of vaseline or grease to the
shaft of the screwdriver.
2) Unscrew the two fixing screws using a
Phillips screwdriver and remove the comfort
kit “2” from the stock.
Matching instructions: the drop change shims and
stock locking plates in the kit are identified by letters.
To ensure a correct drop, always use plates and shims
with the same letter, e.g.: C - CDX – for a 60-RH drop
or C - CSX – for a 60-LH drop.
DX = Right hand
SX = Left hand
3) Unscrew the stock retaining nut “3” (using a
13 mm hexagon wrench).
4) Remove the nut “3”, from the recoil spring
tube and remove the rubber washer “4”,
stock locking plate “5”, stock “6”, cast shim
“7” and drop shim “8”.
WARNING: if the stock spacer “9” doesn't
remain inside the stock, reassemble it with the
seat of plate “5” facing the butt plate.
5) Assemble the drop shim “8” that you have
selected onto the recoil spring tube with the
stamped letter facing the stock.
6) Reassemble the selected cast shim “7” with
the stamped letter (DX or SX) facing toward
the stock.
7) Point the barrel towards the floor and fit the
stock. Engage the stock locking plate “5” in
the stock with the side punched with the
chosen letter facing the butt plate.
