ATI Bulldog ATIG12BDT 12 Gauge Semi-Auto Bullpup 5+1 18.5" Barrel

The ATI Bulldog ATIG12BDT delivers semi-automatic firepower in a compact bullpup configuration that measures significantly shorter than traditional shotgun designs. This 12-gauge platform accepts 2¾" and 3" shells while maintaining a lightweight aluminum receiver construction. The bullpup layout positions the action behind the trigger group, creating a rifle-length barrel in a carbine-sized package.

What Makes This Different

The bullpup design reduces overall length to approximately 26 inches while retaining an 18.5-inch barrel, compared to conventional shotguns that typically measure 38-40 inches with similar barrel lengths. The black steel barrel features a cylinder bore suitable for buckshot and slugs. An integrated Picatinny rail system runs along the receiver top, providing mounting options for optics and accessories without requiring additional hardware.

Key Features

• Bullpup configuration reduces overall length while maintaining full 18.5-inch barrel
• Black aluminum receiver with matte finish resists corrosion and reduces weight
• Picatinny rail system accepts standard optics mounts and tactical accessories
• 5+1 capacity with 2¾" shells, accommodates both 2¾" and 3" magnum loads
• Tan fixed stock and grip provide contrast and tactical appearance
• Semi-automatic gas operation cycles various shell types reliably
• Ambidextrous controls accommodate both right and left-handed shooters

Field performance centers on the gas-operated system that cycles standard hunting loads, tactical buckshot, and slug ammunition. The shorter profile maneuvers effectively in confined spaces while the 18.5-inch barrel maintains velocity for home defense applications. The aluminum construction keeps weight manageable during extended use. Weather-resistant finishes on both steel and aluminum components handle outdoor conditions.
