Hi Avery, one is not a slug barrel. This is a Turkey/Waterfowl Combo. The The 28" waterfowl barrel is a unique addition that provides an extended reach for bird hunting, has a vented rib and front bead sight, and includes a mobile choke set, Full, Modified, Improved Cylinder Choke Tubes.
The 24" barrel has a Blade Front Sight.
Stay safe & have a great day!

In my opinion the 24 inch barrel is no a slug barrel but a turkey barrel (you would not have a slug barrel in a TKY/WTFL combo) I think both barrels are screw in chokes I would ask RIA for a accurate answer armscor.com/ria-usa

Hi Avery and welcome. Yes Sir, Includes: Full, Modified, Improved Cylinder Choke Tubes. 28- and 24-inch barrels.
