The Derya Firearms DY1220US Namlu DY12 12 Gauge Semi-Auto pairs AR-15 inspired ergonomics with a gas-operated, magazine-fed shotgun platform for familiar handling and smooth cycling. Its 20" melonite-treated, threaded barrel works with the included choke system, while the 7075 T6 aluminum upper and lower receivers feature a full-length Picatinny rail and M-LOK handguard for mounting optics and accessories. An adjustable mil-spec stock and textured pistol grip help shooters achieve a comfortable, repeatable shoulder weld.

This DY12 configuration offers a 3" chamber and 5+1 capacity, supplied with three detachable magazines to support different shooting needs. Flip-up front and rear sights provide a clear sight picture out of the box, and the premium soft case keeps the shotgun and included accessories organized between range sessions. Ideal for range use, competition, training, and general-purpose home defense, the DY12 reflects Derya’s focus on robust construction, thoughtful ergonomics, and practical innovation in a modern shotgun design.
