Beretta USA 000520RR A400 12 Gauge 2" 3-Round Semi-Auto Shotgun

The Beretta USA 000520RR A400 12 Gauge 2" 3-Round Semi-Auto Shotgun is a purpose-built tactical platform engineered for law enforcement, military personnel, and civilian defensive applications. Manufactured by Rob Roberts Customs, this semi-automatic shotgun represents a refined approach to close-quarters combat and breaching operations where reliability and speed matter. The 12-gauge chambering delivers superior stopping power, while the 2" chamber dimension optimizes performance with standard tactical ammunition loads commonly used in professional duty environments. This firearm is designed for shooters who demand a modern, semi-automatic action in a compact, controllable package.

The inertia-driven semi-automatic action reduces felt recoil and enables faster follow-up shots compared to pump-action alternatives, critical in high-stress scenarios. The 3-round magazine capacity keeps the overall profile manageable while maintaining sufficient on-board ammunition for tactical operations. Weighing 11.04 lbs and measuring 38 inches in overall length, the Beretta A400 delivers a balanced platform that transitions smoothly between various shooting positions without excessive muzzle rise. The Rob Roberts Customs configuration likely incorporates precision trigger work and reliability enhancements, ensuring consistent ignition and cycling with both buckshot and slug loads. The receiver design accommodates modern tactical accessories and mounting systems, allowing integration with lights, optics, and sighting solutions.

This shotgun benefits law enforcement tactical units, military support elements, and prepared civilians seeking a duty-grade semi-auto shotgun for home defense or specialized applications. The compact overall dimensions suit vehicle storage and room-clearing situations where maneuverability is essential. Compatibility with standard 12-gauge ammunition makes logistics straightforward in operational environments. Prospective buyers should verify local and federal firearms regulations before purchase, as this is a restricted firearm requiring proper licensing and background clearance. Proper training with shotgun fundamentals—sight picture, trigger control, and recoil management—maximizes the platform's effectiveness and safety.
