As I understand it, Mobile and Optima chokes can not be used interchangeably...right? Are Beretta barrels marked so one knows which to use? I understand the chokes are marked.
This came up this week at our club with a used gun just purchased by one of our members.

Yes the barrel has the information on it

And they are not interchangeable.

the optima bore barrels - say OB but there is also optima plus ,which is completely differant

note thread coarseness on mobil vs optima on top
optima + has same as the mobil

 

[Motordoctor]

You also have to watch out for the optima and optima hp. They are different. Check the barrel and check the choke tube

All my semi auto that use optima tubes say optima on the forearm.

Does any body know the bore diameter of the different configurations?

Pretty sure Mobile choked barrels are .723" +/-
Optima choked barrels .732" +/-
