I have a few Beretta Optima (NOT Optima Plus) chokes for sale. I used these with a 2005 Beretta 682 Gold E, they're not the newer Optima Plus ones brought out when the Extrema shotgun came out (whenever that was).
I've got the following :
Red banded Skeet PB-SK-SP (two of these)
Black Banded Three-Quarter PB-IM-SP Improved Modified **
Bronze banded Three-Eighths PB-LM-SP Light Modified
Yellow banded Quarter PB-IC-SP Improved Cylinder ****
Green banded Half PB-M-SP Modified ***
These are all in used condition, not bad for their age, but by no means mint!
