I recently bought a new Beretta over/under which I really like but can't seem to figure out the choke tube thing.
I assumed it was Optima chokes as they advertise on their website yet when I bought additional Optima extended tubes for it they don't fit. The threads are almost twice as long on the extended tubes as they are on the ones that came with the gun.
Is my gun equipped with Mobilchokes? If not, what did it come with? If they are Mobilchokes, can I purchase Beretta extended tubes for it? When did Beretta switch over to Optima from Mobil?
Somebody please enlighten me!!!
