Retay USA
The Retay Gordion 20 Gauge 28" Onyx Semi-Automatic Shotgun is a lightweight, fast-handling semi-auto built for hunters and sport shooters who want a proven inertia-driven platform without the weight penalty of 12-gauge models. At 6 lbs 10 oz, this 20-gauge semi-automatic shotgun delivers low recoil and quick shot-to-shot recovery—ideal for upland game, clay courses, or anyone looking to put more focus on precision rather than fighting felt kick. The inertia-piston design with rotating bolt keeps things simple, reliable, and easy to clean in the field.
The 28" barrel features a lengthened forcing cone optimized for 20-gauge ballistics, paired with Retay's MaraPro five-choke interchangeable system (Cylinder, Improved Cylinder, Modified, Improved Modified, and Full). That flexibility means one gun handles tight woodcock covers, wide-open clays, and everything in between. Chrome-lined Bohler steel construction handles real-world hunting conditions, and the flat 8mm hunting rib keeps your sight picture natural and crisp. A red fiber-optic bead helps you find your target fast when it matters.
Ergonomics are thoughtful: the cross-bolt safety is smooth and intuitive, the automatic anti-repeat trigger keeps you honest, and the sculpted microcell recoil pad softens what little kick a 20-gauge produces. The adjustable shim stock lets you dial in drop at heel and comb to fit your frame, and integrated sling swivel mounts are already built in. The 4+1 magazine capacity (with included limiter for 2-shell sport loads) and polished black anodized aluminum receiver finish round out a shotgun that looks as good as it handles.
Built for hunters and shooters who value efficiency and control, the Gordion 20-gauge semi-automatic shotgun punches above its weight.
