KCI USA KCIMZ001 AR-15 100 Round Drum Magazine 5.56/.223 Black

The KCI USA KCIMZ001 transforms AR-15 platform rifles into high-capacity workhorses capable of sustained fire without frequent reloads. This 100-round drum magazine eliminates the tactical disadvantage of standard 30-round magazines during extended shooting sessions. Built from impact-resistant polymer construction, it delivers reliable feeding for both 5.56x45mm NATO and .223 Remington cartridges.

What Makes This Different

Unlike traditional stick magazines, this drum design distributes cartridge weight evenly around the magazine well, reducing fatigue during extended use. The dual-spring feeding system maintains consistent cartridge presentation even as round count decreases. Standard AR-15 magazines require frequent changes during competition or training, while this drum provides over three times the capacity without modification to the rifle.

Key Features

Field testing demonstrates consistent feeding through various AR-15 configurations including carbine-length and rifle-length gas systems. The magazine functions reliably in competition shooting where rapid follow-up shots are critical. Training scenarios benefit from reduced reload frequency, allowing shooters to focus on fundamentals rather than magazine management. The polymer construction resists impact damage while maintaining feeding reliability in temperature extremes.
