Compact power meets modern ergonomics. The ATI Bulldog 20 Gauge Semi-Auto (ATIG20BDG) brings a bullpup layout to the 20-gauge platform, packing a 5+1 capacity, 18.5" black steel barrel, and aluminum receiver into a maneuverable footprint that’s easy to store, shoulder, and control. With a full-length Picatinny mount and a green fixed bullpup stock, this Bulldog is ready for red dots, flips-up sights, and accessories—delivering reliable semi-automatic cycling in a lightweight, balanced package.
Why Choose the ATI Bulldog 20 Gauge?
Short overall length, full-size performance: The bullpup design moves the action rearward for excellent balance and a compact OAL, while keeping a legal 18.5" barrel for consistent shot patterns and velocity.
Manageable 20-gauge recoil: Enjoy strong terminal performance with less recoil than 12 gauge—great for extended practice and a wider range of shooters.
Accessorize with ease: A Picatinny top rail makes mounting optics and back-up sights simple; side/bottom rails (model dependent) accommodate lights and handstops.
Key Features & Advantages
Gauge/Action: 20 Gauge, semi-automatic gas system for fast follow-up shots and smooth cycling with a wide variety of loads (use ammunition within manufacturer recommendations).
Chamber: 3" (76mm) to accommodate both standard 2¾" and magnum 3" shells (verify load compatibility).
Capacity: 5+1 (tube capacity may vary by shell length; always follow local capacity laws).
Barrel: 18.5" black steel for durability and consistent patterns; threaded muzzle/chokes vary by package—check included choke set.
Receiver: Black aluminum receiver keeps weight down while enhancing rigidity and durability.
Stock: Green fixed bullpup stock with modern texturing for a secure, repeatable shoulder mount; compact geometry favors maneuverability around obstacles.
Controls: Intuitive safety and charging handle placement (layout may vary by production); designed for quick, confident manipulation.
Optics-Ready: Picatinny top rail supports red dots, prisms, or iron sights for fast target acquisition in varied lighting.
Sling-Ready: Attachment points (configuration varies) enable two-point or single-point carry to match your setup.
Ease of Maintenance: Field-strippable design for routine cleaning; follow the owner’s manual for lubrication and service intervals.
Note: Accessory rail configuration, choke system, and minor furniture details may vary by batch. Always confirm your unit’s contents and specs on the box or manual.
Performance You Can Feel
Fast follow-ups: Semi-auto cycling and bullpup balance support quick second shots.
Compact control: Short OAL aids handling in confined areas, vehicles, or tight storage spaces.
Reduced fatigue: 20-gauge recoil and an aluminum receiver keep weight and shoulder impact manageable across long range sessions.
Ideal Use Cases
Range & Training: Run drills with manageable recoil while practicing loading, cycling, and sight transitions.
Home/Property Ready: Compact footprint and optics-ready rail help tailor the Bulldog to your environment (always follow local laws and safe storage practices).
Ranch & Utility: Versatile platform for pest control and general-purpose tasks where a reliable, compact semi-auto shotgun shines.
Setup Tips
Optics: A micro red dot or rugged prism optic pairs well with the top rail; co-witness with flip-up sights if desired.
Chokes & Loads: Pattern your favorite 2¾" and 3" shells; select choke constrictions (if included) based on intended use and pellet size.
Light & Controls: If your model includes side/bottom rail real estate, add a high-candela light and low-profile handstop for control.
Sling: A two-point adjustable sling improves retention and transitions while keeping the compact platform close to the body.
