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?

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.

to support the bayonet while thrusting?

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.

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.
