The Retay USA Gordion 20 Gauge Semi-Auto Shotgun (Retay part no. GOR20BLK-28) runs an inertia-piston system paired with an Inertia Plus rotating bolt for smooth, reliable cycling across a wide range of 20-gauge loads. Finished in black synthetic, the 28-inch barrel is drilled from Bohler steel and chrome-lined for durability, with an optimized, lengthened forcing cone for better pattern consistency. An adjustable shim set lets shooters fine-tune drop at heel and comb to their build, while a sculpted microcell polyurethane recoil pad takes the edge off felt recoil on a long day of shooting. A single bead TruGlo fiber-optic sight and crossbolt push-button safety keep the gun fast and simple to run in the field.
