About this product

The American Tactical (ATI) Bulldog SGA is a bullpup semi-automatic shotgun built for a compact footprint and broad accessory compatibility. It is offered in 12 Gauge with an 18.5-inch steel barrel and a 3″ chamber. The Bulldog ships with a single 5-round detachable magazine, a three-piece choke tube set, adjustable open sights, and both Picatinny and M-LOK rail sections for modular setups.

Key Specifications

  • The barrel length is 18.5 inches.

  • The action is Semi-Automatic.

Included choke tubes and an AR-style charging handle add practical utility for shooters seeking a flexible, ready-to-configure platform.
