The Orthos Arms Black River MFG Battle Drum 12 Gauge Shotgun Drum Magazine delivers high-capacity performance in a compact, purpose-built design. Built around the proven MKA 1919 pattern, this 20-round drum feeds both 2 3/4" and 3" 12 gauge shells and uses a patented EZ Load hand wheel and heat-treated interior components for smooth, reliable operation shot after shot.
This drum magazine is ideal for extended range sessions, training days, or competition stages where fewer reloads help you stay focused on shooting. The clear front cover lets you visually confirm remaining rounds at a glance, while the robust construction and drop-tested design make it a dependable upgrade for compatible 1919-style semi-auto shotguns. Black River MFG and Orthos Arms combine thoughtful engineering with durable materials to deliver a magazine built for long-term use.
