Before starting any operation on your shotgun, make sure that the chamber and the magazine are unloaded! (Carefully read the instructions on gun loading and unloading).
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. 54).
2) If the threaded seat of the choke on the barrel is too dirty, clean it.
