I used to work for Beretta and referenced this chart quite often:

The variety of choke systems used over the years is mind-boggling, but suffice to say the base model shotguns (i.e. 686 Silver Pigeon I and A300 Outlander) use the MobileChoke system and the upgraded shotgun models (i.e. A400 Xplor/Action/Xtreme/Lite and 690/692/DT11) use the Optima HP system. There are exceptions to every rule, but hopefully the link above helps.

Happy New Year!

Hi,

I just purchased a 686 Silver Pigeon I, hasn't arrived yet, it says it has "Optima Bore HP" chokes a/k/a OBHP.

Is this the same as "Optima HP" chokes or the "Optimachoke HP" chokes on the Beretta website?

I called Beretta and they told me they couldn't tell me the correct chokes without the serial number of the firearm, model number wasn't enough. I assume this means that the same models may take different chokes depending on when they were made.

There are quite a few warnings on the Beretta sites not to use the wrong chokes, you'd hope they would have consistent terminology, but apparently not.

Any help is greatly appreciated.

Thank you.

Yes. "Optima Bore Hi Performance", "Optima Bore HP", "OBHP", "Optima HP", are all the same thing.

Who actually manufactures the Optima HP chokes w/ AI Band for Beretta? They resemble Briley's Spectrum line.

I have a friend that recently acquired a Beretta Multi Target model. On 2 separate occasions he has blown the choke tube right out of the gun. Only found one of the two and it shows signs like the tube wasn't screwed all the way into the barrel but when it happened today I had looked at the gun and it was screwed in all the way.
Seems I remember reading about 2 different choke diameters that were causing problems. Is that what I just read in the post above??

If this is so, I had no idea Beretta could make such a blunder as to have fitment confusion with a new choke type.

All my Beretta shotguns have Mobil chokes. Back then the optima bore choked guns were all the rage and I personally never wanted two types of chokes and stuck with buying only older shotguns. Mobil choked guns shoot just fine for me.

My Berettas use Mobile and Optima HP, I've never had an issue with any of them.

Here is the result of using Optima-HP in an Optima barrel. I learned an expensive lesson here, and I also feel Beretta should have some more distinguishing features so that it's a little more obvious to someone not super versed in Beretta.

Learn from my mistake and match the barrel stamp to the choke designation if you buy a Beretta second hand.
