JUST GOT THE MOSSBERG 500 SLUGSTER

I NOTICE IT DOESNT HAVE THE SCREW IN CHOCK ON THE BARREL, IS THIS BARREL REALLY ONLY GOOD FOR SLUGS

OR WILL BUCK SHOT, BIRD SHOP STILL GROUP NICELY WITH THE BARREL

ANY ADVICE ON THE GUN WILL BE APPRECIATED

well I am not certain about buck or bird shot through the rifled barrel but you can get smoothbore barrels for it. They change easily.
