The Derya DY12 is a 12 gauge semi-auto shotgun (Derya part no. DY12.20.US) built around a detachable box magazine instead of a traditional tube, giving it a distinctly tactical layout. The 20-inch barrel keeps the gun short and maneuverable for home-defense and close-range work, while the 3-inch chamber runs standard and magnum 12 gauge loads alike. Flip-up front and rear sights with adjustable settings put fast, precise aiming within reach without needing an optic, and the black synthetic stock and receiver keep the build rugged and low-maintenance. It ships with three 5-round magazines, so reloads are a quick swap rather than a stuffed tube.
