Derya MK12 12GA 20″

The Derya MK-12 is a 12 gauge, semi-automatic, magazine-fed shotgun manufactured by Derya Arms Ltd., a company based in Konya, Turkey, that’s been producing shotguns since around 2000. The MK-12 blends traditional 12 gauge shotgun function with some design elements familiar to AR-style platforms.
