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.

5 of 5 Guaranteed to make you smile May 27, 2021
Reviewer: Jeff K. from Washburn, IL United States  
I mean it's a 100 round AR drum magazine, if you don't smile when you get this/first attach it then I'm not sure what to say. The included speed loaded makes it a breeze to load and so far I have had zero issues with it. I have only loaded it up to around 75 rounds but I hear it is difficult to get the last several rounds in if you load the full 100 (though perhaps after some use/break in this may not hold true). If I ever needed a second one, I would not hesitate to purchase another one of these.

5 of 5 Solid Drum Magazine May 18, 2021
Reviewer: Barry Rhodes from Port Saint Lucie, FL United States  
This is one of the best if not the best drum magazine made as it is easy to load not only with the supplied 5 round loader, but with my 10 round loader as well. I really like the clear rear covers as it provides an easy to see level of your remaining ammunition.

4 of 5 Magazine is quality, nice set-up, carrying case. May 16, 2021
Reviewer: Oregon Shooter from Bend, OR United States  
I got the 100 round magazine while they are still not banned under the liberal govt. The magazine looks well made, and even comes in a nice carry bag with pouches. Shipping was in a bubble bag, so the box was messes up a bit, but the mag is okay, would have been more protected in a box, so not great care in packing.
