Beretta Optima-Choke® HP tubes stand up to the heat of competition. Manufactured from high strength steel and finished in a nickel-alloy coating, these chokes guarantee significant corrosion resistance and have the ability to withstand the rigors of steel shot. Optima-Choke® HP tubes are fully interchangeable on all Beretta barrels that are threaded for Optima-Choke® HP. These choke tubes are designed for 12 gauge shotguns with the optimachoke HP system.
WARNING: Use of the Optima HP choke tube in an Optima firearm (without the HP designation) can cause severe damage to the choke tube and barrel when the shotgun is fired.
