Looks to be about 25 inches. Has screw-in choke. Feels very open. A dime sails right through. This is a rare barrel for the finest gun ever made. How can you stand to be without this barrel if you own a Beretta semiauto? You'll always feel this yearning to add this barrel to your collection and make your gun complete. These are so rare, and only getting rarer, so I feel crazy for letting it go for $250.
