The Derya DY12 shotgun in 12 gauge with an 18-inch barrel (brand part no. DY12.18.US) is a gas-operated semi-automatic built on Derya’s Mag Platform at a USA factory, blending AR-15-inspired ergonomics with 12 gauge firepower. Derya forges the upper and lower receivers from 7075 T6 aluminum for durability, and an adjustable mil-spec stock and pistol grip give shooters familiar, comfortable handling. The shotgun is magazine-fed, feeding from a 5+1 capacity magazine with flip-up front and rear sights, and ships with three magazines — 2-round, 5-round, and 10-round — for hunting or extended-engagement use, accommodating both 2.75-inch and 3-inch shells. Among AR-pattern shotguns in the semi-auto shotguns category, the DY12 favors shooters who want AR-15 handling in a magazine-fed 12 gauge.
