The White Onyx Sporting uses Optima chokes. The other versions of the 686 Onyx series use Mobil chokes.

I don't know where you got that info, but if it came from the Beretta USA web site, I would not depend on it to be up to date. I would also check it often for changes. It appears to me that Beretta must be in the process of gradually changing all Optima models to the Optima Plus choke tubes. They started with the Extrema, then went to the field grades of 391 Urika, now they have added some O/U's. The trend is bound to continue, because it just doesn't make good business sense for them to continue to use two different Optima chokes.

As recently as January 2004 Beretta USA was saying on their web site that the Optima Plus chokes were used ONLY on the Extrema, but even at that time they were selling 391 Urikas with the Optima Plus chokes. Now 9 months later we have a list of 6 models that use the Plus chokes. I predict that within a year Beretta will not be making any new guns with the Optima chokes.

The white onyx doesn't have opt chokes, it has the mob chokes.

The 686 essential has mob chokes.

The White Onyx Sporting does have Optima barrels and chokes -- that's why I bought one -- but the field White Onyx and the White Onyx Pro do not. Apart from the receiver, these are different guns and priced differently as well.<p>

My Urika 12 came with the mobile choke system. Must be when they were made to depend on which choke system they use?

What is the difference between the Optima + and the standard Optima tubes? Is the + for steel shot?

The Optima Plus tubes are used in the Field guns. It started in the Extreme (3.5"), progressed to the Teknys field then the 391 Urika Field.
The Competition, including the Sporting/Trap/Skeet guns, were given the Optima tubes. They both, Field and Competition, have the Optima Bore just not the same tubes. I have not put them on the scales but, the Optima Plus feel heavier than the Optima's. :?

A year later......The confusing thing is the new White Onyx Sporting uses the Optima chokes and as you state the old one doesn't. Why Beretta makes the changes it does baffels me.

It is my understanding that the guns with the optima barrels are back bored and have lengthened forcing cones. Is this correct?

Backbored, yes. Forcing cones, I think so.

the nicest finished set of cones i have ever seen were in my gold e, the only way to tell they were there was with a bore mic. the taper was almost 5'' long, and polished like the barrel----nicely done, and done factory. not all i have looked at were finished like that, but all were lengthened

Optima chokes are designed primarily for Sporting uses. Optima Plus chokes are designed primarily for Hunting uses. The way it was explained to me was that the sporting shooter GENERALLY shoots a LOT Of lighter pressure loads at slower speeds using lead shot while a hunter uses harder shot (ie steel, etc.) and higher speeds and pressures.

Also, if the gun has Optime or Optima plus barrels, the barrel is overbored to .733-735 and has lengthened forcing cones as well.

Beretta made a run of DT10 commemorative models for the 100th Anniversary of Vandalia and The Grand in 1999. The chokes in at least some of those guns are called "Overbore", and do not fall into the optima or mobil choke lists as posted.

They are an entirely different choke tube, and neither the Optima or Mobil choke will fit in my Vandalia 100th Ann. DT10.
