Benelli USA /Mobil Choke Tube 12 Gauge 3" 4-Round Shotgun

The Spandau Arms 21000185 S2 Field 12 Gauge Semi-Auto is a modern inertia-operated shotgun purpose-built for tactical operations, home defense, and field use where reliability under varied conditions is non-negotiable. Designed around proven inertia-driven operating principles, this 3-inch 12 gauge delivers consistent cycling across light and heavy loads without requiring adjustment or part changes—a critical advantage in duty or emergency scenarios where ammunition variety is unavoidable. The 24-inch ventilated rib barrel with Benelli/Mobil choke compatibility positions this platform as a flexible, mission-ready choice for law enforcement, armed security, and serious civilian operators.

The inertia operating system cycles rounds reliably whether you're running target loads or full-power buckshot, eliminating the maintenance-heavy gas tube adjustments found on piston-driven competitors. The drilled and tapped receiver accepts modern optic mounts, enabling rapid-target acquisition with red dots, reflex sights, or traditional scope systems. The ventilated rib barrel reduces muzzle jump and provides a superior sight picture during rapid follow-up shots, while the Benelli/Mobil choke tube system grants shooters field-configurable shot patterns for specific engagement distances. At 8.95 pounds, the S2 Field balances controllability with minimal shooter fatigue during extended tactical or hunting applications. The fixed black polymer stock ensures durability in harsh conditions and straightforward maintenance without compromising ergonomics.

This shotgun serves tactical professionals, armed security personnel, hunters, and civilian home defenders who demand a proven platform that cycles reliably regardless of load variation. Law enforcement and military operators appreciate the inertia design's minimal cleaning requirements and field reliability—critical factors in high-tempo training or emergency response. The 3+1 capacity (three rounds in magazine, one in chamber) delivers quick follow-up shots without reloading, while the drilled receiver accepts tactical accessories including slings, lights, and optics mounts. Compatibility with standard Benelli/Mobil choke tubes means shooters can transition between cylinder bore, improved cylinder, or tighter patterns within seconds, adapting to close-quarters or distance scenarios. Whether for breaching, patrol, or precision bird hunting, the Spandau Arms S2 Field 12 Gauge Semi-Auto delivers dependable, low-maintenance performance.
