ATI ATIG20BDG Bulldog 3" 6-Round Bullpup Stock Bullpup Rifle

The ATI ATIG20BDG Bulldog 20 gauge semi-automatic shotgun represents a modern take on compact tactical shotgun design, engineered for operators who require maximum firepower in minimal footprint. This 3-inch chamber bullpup-configuration shotgun delivers the handling characteristics demanded by law enforcement entry teams, military personnel, and civilian defensive shooters operating in confined spaces. The bullpup design moves the magazine well and action rearward, reducing overall length while maintaining a full-length barrel—a proven configuration that has seen real-world validation across decades of tactical operations.

Built by American Tactical Inc., the Bulldog features a semi-automatic operating system with a 6-round capacity, purpose-designed for rapid follow-up shots in dynamic tactical scenarios. The 3-inch chamber accommodates both 2.75-inch and 3-inch 20 gauge ammunition, providing shooters with flexibility in load selection for varied mission profiles. Weighing 10.2 pounds with a 32.7-inch overall length, the platform achieves optimal balance between controllability and muzzle velocity, while the compact 11.2-inch height enables deployment from vehicles, low-profile positions, and tight quarters where conventional shotgun profiles prove unwieldy. The semi-automatic action reduces shooter fatigue during extended operations and ensures consistent cycling across ammunition types.

The ATI ATIG20BDG Bulldog excels for tactical teams requiring precision shot placement in close-quarters combat, home defense specialists prioritizing maneuverability in hallway environments, and shooters with recoil sensitivity who benefit from the reduced impulse of 20 gauge ammunition. Law enforcement agencies have long favored 20 gauge platforms for their reduced over-penetration risk in urban environments and lower liability exposure. This firearm integrates seamlessly with standard 20 gauge ammunition logistics and pairs effectively with optic-ready platforms common in modern tactical doctrine. Proper training and adherence to all applicable federal, state, and local firearms regulations are essential for lawful operation.
