The Mossberg 590A1 Pro in 12 gauge (brand part no. 50797) is a pump-action shotgun built around a 20-inch barrel, giving defensive and tactical shooters a manually cycled platform built to the same military-spec standard as the original 590A1. Mossberg finishes the 590A1 Pro in Tungsten and equips it with adjustable ghost ring sights for precise aim under stress. Among shotguns in the semi-auto shotguns category, this listing is a pump-action 590A1 Pro rather than a semi-automatic — shooters cycle each round manually via the forend slide.
