Bruce, you can always go the screw in choke route. Years ago off the cuff I bought a 16 ga 4E that someone had briley screw in chokes installed. Apparently the original 28" barrels had the ends damaged and someone cut 2" off and had the briley chokes installed. It's a really neat gun and shoots very well not to mention there were only like 20 some 4E's ever produced in a 16 ga made
