This is a FedArm 12-gauge semi-automatic AR style shotgun, similar to the MKA 1919 imported by Akdal and RAAC, or the improved version: BR-99 previously imported by others. The gun is brand new in the box, never fired. It is semi-automatic, gas operated, and has a synthetic stock that has been fixed into the collapsed position and permanently pinned. The shotgun is chambered for either 3” magnum shells or 2 ¾” standard shells, has a 20” barrel with tube choke, and a manual safety. This is designed for tactical use with its AR style platform. It features a high quality turned and gauged 4140 steel barrel and nearly all internal parts are machined from billet stock (not cast). This shotgun is made with performance and durability in mind, unlike cheap knock-offs on the market. This shotgun is from one of the largest shotgun factories in Turkey which produces for all the major importers in the USA, and is sold in big box stores like Academy, Dicks, Cabela’s, and others. All parts are made from government certified mil-spec steel and forgings, and are police grade (not consumer grade).
