Works great on S&T M1918 BAR. Feeds flawlessly on semi and full auto. Made out of carbon fiber ABS. Made for Angel Customs Firestorm and Thunderstorm drum. Don't care about historical accuracy or want to create something cursed/fallout themed? ♦️IMPORTANT♦️: You are only buying adapter to fit on the drum. Not the drum or the gun. If you have any further questions let me know.
