re: Beretta Optima plus choke

I believe they are totally different barrel designs. I'd imagine Beretta would have something similar, but aftermarket has just as good chokes. Just know with every Benelli ive had or used, and people I know use, the chokes always come loose after shooting some so make it a habit to safely tighten it every so often when hunting or shooting. (just make sure to not shoot yourself). I've been told Berettas do that too.
