American Tactical Bull-Dog 12 Gauge Semi-Auto Bullpup Shotgun – 18.5" Barrel

Overview

Offered here is an American Tactical Bull-Dog semi-automatic bullpup shotgun chambered in 12 gauge, presented in new condition.

The ATI Bull-Dog is a compact magazine-fed bullpup shotgun developed by American Tactical Imports in partnership with Turkish manufacturer PARS MFG, combining modern tactical ergonomics with the proven performance of a semi-automatic 12-gauge platform.

Its bullpup configuration places the action behind the trigger, allowing the shotgun to retain a full 18.5" barrel while keeping overall length to approximately 26 inches, improving maneuverability without sacrificing ballistic performance.
