New 18.5" barrel on Brownells $115
Magazine Tube $30
Magazine Spring $5
$150 in parts minimum. If you have to use a gunsmith to change it add at least $50 putting you at $200. You can get a brand new 500 18.5" 5+1 for $250-300 or trade your 590 for the 500 and probably pocket some money. You may also have warranty issues with Mossberg if you change it around to much or at least you will confuse them when you talk about your 18.5" 590 since they don't make one.
