Which shotguns does the Beretta recoil reducer fit ?

The Beretta Inertia Recoil Reducer fits into the wood stocked models of our 12 gauge 391 Urika and Teknys shotguns that came from the factory with Optima barrels. You can identify these shotguns by looking for "Optima" stamped on the fore-end. Starting in 2005, wood stocked 20 gauge 391 Teknys Sporting shotguns will also accept this reducer. Check the proof mark for the year of production on your barrel to determine if your 20 ga is a 2005 or newer model. Over-unders, side by sides and Synthetic stocked shotguns of any model will not accept the reducer.  Please review the proof mark chart below:
