A:keep it at least 18.25" long for legal reasons
Measured from the face of the breech with the action closed. Where you get in trouble is measuring the barrel outside the action. Why bother? Get a spare barrel in the length you want.
I've got two Mossbergs, one manufactured sometime before 1967 (no serial number). I'm also a certified Remington armorer. Which one would I pick? For the price, a Mossberg. Not enough difference in quality and reliability to make up for the price diff.
