Wanted: Mossberg 590 barrel 20”

Looking for a mossberg 590 barrel approx 20”, my mag tube sticks out further than my 18.5” and I’m not a huge fan. Bigger is okay too just not any less than 20”. 

Mossberg 500 barrels won’t work, piece for the mag tube is smaller compared the 590. 

I am Located near Trenton, ON but don’t mind travelling for the right deal.

Photo of my 590 for reference and the mag tube. 

Thanks!
