KCI 100-Round AR15/M4 Drum Magazine


The KCI 100-Round Drum Magazine is designed to fit AR15 style rifles chambered in .223 Remington or 5.56x45mm NATO; providing reliability and smooth feeding. Reinforced steel feed lips make the 100-round drum magazine extremely durable.

Ready for any contingency, the magazine exceeds NATO military specifications with an estimated life cycle of 50,000 rounds. With a unique rotation device and low torsion stress springs, it can be pre-loaded and stored indefinitely at the full 100 round capacity.

The drum magazine feeds alternately from the right and left drums, resulting in a fixed center of gravity while firing. The reinforced feed lips, tension arms and supports are made of solid steel. While a loaded aluminum 30 round magazine weighs about 1.5 lbs, the KCI USA drum weighs only 2.2 lbs unloaded and 5 lbs loaded.

Disassembly for cleaning and lubrication is simple and is covered in the manual provided. There are two short belts inside with dummy cartridges for reliable feeding.

A simple loader is included with each magazine making loading fast and easy. Snap the loader on to the tower in the direction indicated by the cartridge-shaped pictogram. Place the magazine on a firm surface and drop 5 rounds into the loading slot. Push the down firmly and the rounds are fed into the drums.

Manufactured in Korea, the package includes the KCI USA 100 Round Drum Magazine, Operator’s Manual, Carrying Pouch, Graphite Lubricant and Loader.

Since I haven't used it yet, this review will attest to the fast shipping and handling after placing and order.  This place is top notch.  I hope to try out the drum magazine in the near future.
