The return spring is also located around the same support tube which is concealed by an enlarged polymer handguard. The MKA 1919 barrel can be quickly removed from upper receiver. To charge the shotgun, the charging handle on the receiver needs to be pulled. The upper receiver is manufactured from an aluminum alloy while the lower receiver, along with pistol grip and shoulder stock, is manufactured as one piece from impact-resistant polymer. Akdal MKA 1919 semi-automatic shotgun has a 5 round detachable box magazine. The magazine catch is identical to the M16magazine catch and is located on the lower receiver.
