O.F. Mossberg & Sons, Inc. is proud to announce that it has been awarded a contract for approximately $11.6 million dollars to supply the U.S. Army with additional Mossberg 590A1 pump-action shotguns. First adopted by multiple branches of the U.S. Military in 1987, the Mossberg 590 proved its reliability and durability by successfully completing the rigorous MIL-SPEC 3443E testing protocol.

Following its adoption, the U.S. Military requested a purpose-built variant capable of withstanding sustained, high-volume use in the most demanding environments. That requirement led directly to the development of the Mossberg 590A1 — a strengthened, mission-ready evolution of the original 590 platform.

“Mossberg is honored to receive an additional contract from the U.S. Department of Defense for the battle-proven 590A1 shotgun,” said John MacLellan, Mossberg’s Vice President of Sales and Marketing. “This award reflects our long commitment to supplying rugged, mission-capable firearms built to exacting standards — and reinforces our pledge to provide timely solutions that support the safety and effectiveness of U.S. service members.”

Mossberg 590A1 shotguns are based upon the time-tested Mossberg 500 pump-action platform, with non-binding twin action bars; positive steel-to-steel lock-up; and an anti-jam elevator for smooth, reliable operation; dual extractors; anodized aluminum receiver for added durability, and ambidextrous top-tang mounted safety. The Mossberg 590A1 also features a heavy-walled barrel; metal trigger guard; metal safety selector switch; and parkerized finish.
