Mossberg 590A1 Tactical 12GA 8+1 20" Heavy Barrel Parkerized

The Mossberg 590A1 Tactical delivers military-grade reliability with its heavy-walled barrel and mil-spec construction. This 12-gauge shotgun combines proven combat durability with tactical versatility for law enforcement, military, and civilian applications.

What Makes This Different

The 590A1 features a heavy-walled barrel that withstands sustained firing schedules without degradation, unlike standard sporting shotguns. Military specifications require components to pass rigorous testing protocols, including a 3,000-round proof test. The aluminum trigger guard and metal safety button provide enhanced durability over polymer alternatives found in civilian models.

Key Features

• Heavy-walled 20" barrel rated for extended high-volume shooting
• Parkerized finish provides superior corrosion resistance in harsh environments
• Drilled and tapped receiver accepts optics and tactical accessories
• Metal trigger guard and safety button exceed mil-spec durability standards
• Synthetic stock resists weather and impact damage

Field performance demonstrates consistent cycling across ammunition types from light target loads to heavy 3" magnum shells. The action remains smooth after thousands of rounds, maintaining the tight lockup essential for accuracy. Law enforcement agencies rely on this platform for patrol duty, while competitive shooters appreciate the consistent performance in 3-gun matches.
