The sleek profile of a 535 barrel coupled with a shortened magazine tube provides comfortable balance and swing. This gun is all-terrain, all-purpose with a 3.5" chamber for the widest range of useage. The 28" vent-ribbed barrel has a white front bead and comes with the Accu-Choke set of M, F and IC choke tubes. The 535 barrels are not interchangeable with other Mossberg shotguns.
