Akdal MKA 1919 12-gauge semi-automatic shotgun is the new product from Turkish company Akdal Arms. This weapon is intended for civilian and security use, and mimics the famous M16 rifle in its layout and placement of most controls. It is remarkably light for its caliber and size, because of extensive use of modern, high strength plastics.
