Derya DY1220US 12 Gauge Semi-Auto Shotgun 20" Threaded Barrel 5+1

The Derya DY1220US delivers reliable semi-automatic performance with modern tactical features for sporting and defensive applications. This Turkish-manufactured shotgun combines proven gas operation with contemporary materials and mounting options. The 20-inch threaded barrel provides versatility for suppressors or choke systems while maintaining maneuverability.

What Makes This Different

Unlike traditional hunting shotguns, the DY1220US features an aluminum receiver with integrated Picatinny rail for optics mounting. The adjustable polymer stock allows length-of-pull customization from 12.5 to 14.5 inches, accommodating different shooter builds and gear configurations. The melonite-treated barrel offers superior corrosion resistance compared to standard blued finishes, extending service life in harsh conditions.

Key Features

• Gas-operated semi-automatic action cycles 2¾" and 3" shells reliably
• 20-inch threaded barrel (½-28 TPI) accepts suppressors and muzzle devices
• Black anodized aluminum receiver with full-length Picatinny rail
• Adjustable polymer stock with pistol grip configuration
• 5+1 capacity with removable magazine system
• Melonite barrel treatment for enhanced durability and accuracy
• Compatible with standard 12-gauge ammunition including buckshot and slugs

Field testing shows consistent cycling with various loads from light target rounds to heavy waterfowl shells. The gas system self-adjusts for different cartridge pressures, reducing maintenance requirements. Competition shooters appreciate the flat-top receiver for red dot mounting, while the threaded barrel accommodates tactical suppressors for reduced sound signature. The synthetic furniture resists weather and impacts better than wood alternatives.
