F/S Beretta 30" 28 gauge barrels for 12 gauge frame

These barrels are getting harder and harder to find. Beretta 680 682 686 687 - 30" 28 gauge sporting barrels for 12 gauge frame. Mobilechoke threads and comes with 4 chokes. Absolutely MINT condition. I also have a Beretta 686 12 gauge R&I that would be perfect for a small gauge sporter build with mechanical triggers already done by Coles. These barrels are not fit to that receiver. Barrels are offered at $1600. Thanks and good shooting, Rey
