Banish 20 Adapter Features The Banish 20 Adapter is machined from stainless steel for strength and corrosion resistance then finished in a black nitride coating that holds up to repeated firing cycles and field use. Direct thread mounting provides a secure repeatable connection between the Beretta Optima HP choke system and a compatible Banish suppressor. Because it is purpose built for this specific host the adapter threads on without modification to the barrel or choke system. This lets shotgun shooters add suppression to their 20 gauge Beretta without sacrificing the factory choke interface. At roughly 0.09 pounds the adapter adds negligible weight or balance change to the shotgun keeping the gun s natural point of aim intact. The black finish matches most factory shotgun finishes so the adapter blends in rather than standing out on the muzzle. Shooters running suppressed shotguns for hunting or pest control gain a quieter more comfortable shooting experience with this adapter in place. The Banish 20 Adapter is a straightforward dedicated solution for anyone wanting to suppress their Optima HP equipped shotgun.
