KCI USA 100 Round Drum Magazine 5.56/.223 AR-15 MZ067 Black

The KCI USA MZ067 transforms standard AR-15 platforms into high-capacity systems with its 100-round drum magazine design. This extended capacity magazine eliminates frequent reloading interruptions during extended range sessions and competitive shooting events. Built specifically for 5.56x45mm NATO and .223 Remington cartridges, the MZ067 integrates seamlessly with mil-spec AR-15 lower receivers.

What Makes This Different

Unlike standard 30-round magazines, the MZ067 drum configuration provides over three times the ammunition capacity while maintaining reliable feeding mechanics. The dual-spring system operates independently of traditional box magazine constraints, allowing for consistent cartridge presentation throughout the entire 100-round cycle. This design reduces the tactical disadvantage of frequent magazine changes during critical shooting scenarios.

Key Features

• 100-round capacity for 5.56x45mm NATO and .223 Remington cartridges
• Dual-spring feeding mechanism ensures consistent cartridge presentation
• Polymer construction with reinforced steel internals for durability
• Standard AR-15 magazine well compatibility with mil-spec receivers
• Loading window indicator shows approximate round count during use
• Anti-tilt follower system prevents feeding malfunctions
• Matte black finish resists scratches and environmental wear

The MZ067 performs effectively in competitive shooting disciplines where sustained fire capability provides tactical advantages. Three-gun competitions benefit from reduced reload frequency, while tactical training scenarios can incorporate realistic ammunition loads. The drum's robust construction maintains feeding reliability through extended firing schedules, though proper maintenance intervals should be observed for optimal performance.
