KCI USA AR-15 Rifle Drum Magazine .223/5.56x45mm 50/rd Black

The KCI USA AR-15 Rifle Drum Magazine in .223/5.56x45mm with 50-round capacity delivers high-volume ammunition storage for tactical rifle platforms. Engineered specifically for AR-15 style firearms chambered in .223 Remington or 5.56x45mm NATO, this drum magazine is built for operators who demand extended firing cycles without frequent reloads—whether conducting range qualification, training evolution, or field operations where magazine changes create tactical pauses.

The transparent polymer magazine body allows you to visually verify ammunition status and round count at a glance, eliminating the need to assume you're loaded. KCI incorporated a front-load assist system using linked followers and a heat-treated flat spring specifically designed to reduce loading resistance—a critical feature when hand-loading 50 rounds of 5.56 ammunition, which typically requires significant force. The 2.06-pound weight and 6.25 x 5 x 9-inch profile fit standard AR-15 magazine wells without modification. Each magazine ships with an operator's manual, protective carrying pouch, and graphite lubricant to maintain smooth feeding and bolt-carrier performance over extended use cycles.

This 50-round drum is optimal for training, tactical courses, and dedicated AR-15 shooters who prioritize ammunition capacity over magazine portability. It suits carbine-length platforms and is compatible with standard .223/5.56 full metal jacket ammunition. The lifetime warranty covers manufacturing defects, provided the magazine remains fully assembled—disassembly voids warranty coverage. Graphite lubrication and regular cleaning maintain reliable feeding and extend service life in high-round-count environments.
