Optima choke tubes are one of the most popular early choke systems developed for Beretta shotguns. These choke tubes can be found in just about every diameter. Most choke manufacturers offer Optima choke tubes for waterfowl and turkey hunting.
Shotguns that accept Optima chokes will typically be marked “OB” on the barrel after the gauge. Only older Beretta shotguns use these chokes, as they aren’t compatible with the newer Optima Plus or Optima HP chokes. Consult Beretta.com or see the choke interchange lookup if you think your shotgun may use Optima chokes for the latest compatibility list.
