It has a slug barrel on it currently, but I guess it isnt beyond comprehension that someone took a bird barrel and made it into a slug barrel with the right sights
I have a Mossberg 500 16ga that my father-in-law gave to me for my boys to deer hunt with. The barrel is horribly rusted/pitted so it wont pattern worth a darn. I CAN find slugs. Its a pre-1967 mod ...
