ATI Bulldog ATIG20BDG 20 Gauge Semi-Auto Bullpup Shotgun 18.5"

The ATI Bulldog ATIG20BDG delivers compact firepower in a space-saving bullpup configuration that measures just 28 inches overall. This 20-gauge semi-automatic shotgun places the action behind the trigger group, creating a full-length 18.5-inch barrel in a package shorter than most carbines.

What Makes This Different

Unlike traditional shotgun designs, the bullpup configuration shifts weight toward the shooter's shoulder for improved balance and maneuverability. The aluminum receiver keeps weight down to approximately 7.2 pounds while maintaining structural integrity. Standard shotguns with similar barrel lengths typically measure 38-40 inches overall, making the Bulldog's compact 28-inch profile ideal for confined spaces.

Key Features

• 18.5-inch black steel barrel with 3-inch chamber capability
• 5+1 capacity with quick-loading magazine system
• Picatinny rail mount for optics and accessories
• Black aluminum receiver with corrosion-resistant finish
• Fixed green polymer bullpup stock with integrated pistol grip
• Semi-automatic gas operation for reliable cycling
• Ambidextrous safety and controls

The gas-operated system cycles 2.75-inch and 3-inch shells reliably across various loads from light target rounds to heavy waterfowl ammunition. The integrated Picatinny rail accepts standard optics mounts, allowing for red dot sights, scopes, or tactical lights. The bullpup design maintains full barrel length for velocity while reducing overall weapon length by 25% compared to conventional shotguns.
