Just found this

The new muzzle can be used on all spear guns featuring a barrel with an internal diameter of 25.6mm (Omer aluminum barrels) or 25.0 mm (Omer carbon fiber barrels).
Cod. ex 16 for all Omer spear guns featuring an alluminium barrell
Cod. ex 17 for all Omer spear guns featuring a carbon fiber barrell
The muzzle features a small stainless steel clip inserted in the bottom part. This clip allows the reel line to pass through after shooting, without any interference.
The assembly on the barrel is done with a pin manufactured in a highly technical plastic material called Grivory GV5H. This material allows the pin to be as resistant as metal pin but avoiding the usual oxidation.
