The Mossberg 590A1 Retrograde shotgun combines the classic aesthetics of tactical pump shotguns with advanced functional features. This model pays homage to the original Mossberg tactical pumps, featuring a walnut stock with a checkered grip and vented recoil pad, and a matching walnut forend, which not only provides a vintage look but also enhances shooter comfort and control. The heavy-walled barrel, metal trigger guard, and safety highlight the 590A1's durable construction, while the parkerized finish ensures resistance to corrosion and wear, essential for prolonged field use. Functionality is central to the Mossberg 590A1 Retrograde, equipped with MIL-SPEC construction that supports reliability under rigorous conditions. Key operational features include dual extractors for consistent shell removal, positive steel-to-steel lockup for enhanced stability, and twin action bars that prevent binding and ensure smooth cycling. The shotgun’s receiver is drilled and tapped, ready for optics or accessory mounting, which is highly valued in tactical and hunting scenarios. It includes a clean-out magazine tube that facilitates maintenance and an anti-jam elevator that ensures smooth feeding under stress. With an ambidextrous safety mounted on the top, the 590A1 Retrograde caters to both right and left-handed users, making it a versatile choice for diverse shooting environments.
