The Mossberg 590A1 Professional Series in 12 gauge finished in Marinecote (brand part no. 50794) pairs the duty-proven Pro Series platform with Magpul furniture and a corrosion-resistant coating built for wet, humid environments. Mossberg equips this 590A1 Pro with adjustable ghost ring sights, an 18.5-inch heavy-walled barrel, and a fixed cylinder bore choke. The shotgun feeds from a magazine with a 6+1 capacity, and Marinecote’s corrosion resistance makes it well suited for marine, coastal, or humid climates. Among pump-action shotguns, this 590A1 Pro favors buyers in humid or coastal environments who want Magpul ergonomics.
