Internal choke (when supplied)
Before attempting any work on your M4 make
sure that the chamber and the magazine of your
shotgun are unloaded.
(See the instructions on loading and unloading).
WARNING: before using the shotgun, make
sure that the barrel has a choke correctly
installed.
WARNING: the internal choke correctly mount-
ed must not stick out of the barrel’s muzzle. Use
only the Benelli internal chokes with a length
which correctly fits the barrel.
To change or clean the internal choke, proceed
as follows:
1) Unscrew the internal choke using the special
choke wrench supplied with the shotgun and
extract it completely from the barrel seat (fig.
72).
2) If the threaded seat of the choke on the barrel
is too dirty, clean it by spinning round the
threaded part of the proper wrench (fig. 73).
NOTE: before re-using the shotgun, make sure
that the choke wrench has been removed from
the barrel’s muzzle.
3) Reassemble on the barrel seat the kind of
choke required, taking care to insert the non-
threaded part inside the barrel, before screw-
ing the choke on the barrel’s thread (fig. 74).
NOTE: the choke correctly mounted must not
stick out of the barrel’s muzzle.
