ATI Bulldog ATIG20BDT 20 Gauge Semi-Auto Bullpup Shotgun 18.5"

The ATI Bulldog ATIG20BDT transforms the traditional shotgun platform with its compact bullpup configuration, delivering full-length barrel performance in a package nearly 10 inches shorter than conventional designs. This 20 gauge semi-automatic accepts 2.75" and 3" shells, providing versatility for both sporting and defensive applications.

What Makes This Different

The bullpup design relocates the action behind the trigger group, achieving an overall length of just 26.5 inches while maintaining an 18.5-inch barrel. Standard shotguns with equivalent barrel length typically measure 38-40 inches overall. The aluminum receiver reduces weight compared to steel alternatives while maintaining structural integrity under repeated firing cycles. The integrated Picatinny rail system eliminates the need for aftermarket mounting solutions.

Key Features

• Bullpup configuration reduces overall length by 25% compared to traditional shotguns
• 18.5-inch black steel barrel with 3-inch chamber capacity
• Matte black aluminum receiver with corrosion-resistant finish
• Integrated Picatinny rail for optics and accessories
• Tan polymer fixed stock with textured grip surfaces
• 5+1 round capacity with standard 2.75" shells
• Semi-automatic gas operation for rapid follow-up shots

The gas-operated system cycles reliably with various shell weights from light target loads to heavy waterfowl rounds. The compact profile excels in confined spaces while the full-length barrel maintains velocity and accuracy at extended ranges. The low-profile design works effectively for home defense scenarios where maneuverability matters, while the 20 gauge chambering provides substantial stopping power with manageable recoil.
