Mossberg brings back a tactical pump

Originally offered as an RSR Group exclusive in 2014, the 590A1 Magpul 9-Shot shotgun returns to Mossberg’s full line this year. Pairing the 12-gauge pump-action platform with Magpul’s SGA adjustable stock and MOE forend and an XS Sights’ Ghost Ring sight system helps elevate the performance of this tactical shotgun to the point where it is the only pump to pass U.S. Armed Services MilSpec 3443 requirements for endurance, accuracy, and quality.

Based on Mossberg's proven 500 pump action platform, standard features of the 590A1 include non-binding twin action bars, positive steel-to-steel lock-up and anti-jam elevator, dual extractors, an anodized aluminum receiver, and an ambidextrous top-mounted safety. Enhancements to the 590A1 include nine-shot capacity with 2¾-inch shells (one less with 3-inch shells), 20-inch heavy-walled barrel with an open-ended flush magazine-tube design, and a durable Parkerized finish on exposed metalwork. The adjustable stock allows a user to customize length of pull (from 12.25 inches to 14.25 inches) through a series of half-inch stock inserts. Optional cheek risers can also be used with optics or raised sights. The MOE forend features an extended length and is designed with front and rear hand stops for improved manipulation. The forend is also compatible with Magpul MOE rails for ease of adding accessories. Completing this 590A1 package is the XS Ghost Ring sight, consisting of an anodized-aluminum receiver-mounted rail and sight (adjustable for windage and elevation) paired with an AR-style white-stripe front sight. SRP: $836. (
