Kci Usa Inc Kci-Mz067 Mag Ak 556 100Rd Drum
The KCI USA 100-round drum magazine for AK-platform rifles chambered in 5.56 NATO is built for shooters who demand high-capacity firepower without frequent reloads. If you run an AK-pattern rifle in 5.56—whether for range sessions, training, or competitive shooting—this polymer drum lets you stay in the fight longer. At 100 rounds, it's a serious upgrade from standard box magazines, and the robust polymer construction is designed to handle the demands of active shooting.
KCI has engineered this drum to work reliably with 5.56 NATO and .223 Remington ammunition in compatible AK 556 platforms. The black polymer construction keeps weight down while maintaining durability, and the high capacity means fewer mag changes and more time behind the gun. Whether you're running drills at the range or stocking up for training days, a 100-round drum changes the rhythm of your shooting session.
Like any high-capacity magazine, proper maintenance and testing with your specific firearm before relying on it in the field is the responsible approach. Function can vary based on ammunition type, magazine condition, and rifle setup, so take the time to verify reliable feeding with your rounds and gun before counting on it in a critical scenario.
