    what exactly is the difference between a normal barrel and a "heavy-walled" barrel on a Mossberg, besides being thicker? properly maintained a normal barrel should last forever...what's the reasoning behind a thicker barrel? actual blunt force maybe?

    well for me.....its in case I fall on a darn tree and dont bend the barrel

    have a 590A1 and a Breacher both use the same HB...and its alot heavier than a 500

    Maybe it handles heat better? I always figured that's why target rifles have really thick barrels, less variation in shot due to the barrel warming up.

    Most likely to pass the "mil-spec" drop tests and such.

    Doesn't the bayonet attach to the mag tube on the Mossberg?

    Probably for reasons all of the above.

    The HB is thick enough to thread for a choke like my factory accu-choked 18.5" heavy barrel. They would also be less likely to burst when firing with water in them. More weight = less kick.

    But it also makes it harder to swing too. Unless you have a valid reason for needing the heavy barrel or are in good shape and/or a little on the big side you may want to consider sticking with the standard barrel. This goes double for the extended mag. variants.

    When in doubt, use it as a baseball bat.
