The Mossberg 590A1 Tactical in 12 gauge with a 20-inch parkerized barrel (brand part no. 51668) is a duty weapon proven with military and law enforcement agencies worldwide. Mossberg pairs the heavy-walled barrel with a ghost ring rear sight, an ambidextrous top tang safety, and a fixed stock with a built-in storage compartment that carries four additional shells. Dual extractors, twin action bars, and positive steel-to-steel lockup keep the action cycling reliably under hard use. Among pump-action shotguns, the 590A1 Tactical favors buyers who want onboard spare-shell storage built into the stock itself.
