If you put a poly choke or an adapter to use screw in chokes you could use one . Also the sights are NG for trap ,in fact the factory front sights are above the barrel on the gas piston houseing ( not in line with the barrel),you will have to get used to the sights or change them . If your used to putting your front sight bead at the bottom of your target,you will be shooting low.You will need to point at the center. I solved this problem by useing a AK tower type front sight with an AR 15 center post ,its dead on now .
