The Black River MFG Battle Drum 12 Gauge Shotgun Drum Magazine delivers high-capacity performance in a compact, rugged package. Built around the proven MKA 1919 pattern, this 20-round drum is engineered for semi-auto 12 gauge shotguns and uses a patented EZ Load wheel and heat-treated interior components to keep shells feeding smoothly. The striking black and red body with a clear front cover lets you visually confirm remaining rounds at a glance.

This Battle Drum is compatible with 2 3/4" and 3" 12 gauge shells and is designed to run in a wide range of AR-12 and 1919-style shotguns, including popular models from Typhoon Defense, Rock Island, Panzer Arms, and more. Its polymer construction keeps weight manageable while still standing up to drops, impacts, and harsh conditions, making it a solid choice for extended range sessions, training days, or competition-style shooting. Black River MFG backs the design with careful inspection and testing that reflects their focus on reliability and practical innovation.
