Product Description
The KCI USA .223 Remington / 5.56 NATO 30-Round Aluminum Magazine (KCI-MZ018) offers reliable, high-capacity feeding for AR-15 and M4 rifle platforms at an exceptional value. Engineered as a lightweight, standard STANAG-compliant feeding device, this 30-round magazine is built to military specifications to deliver smooth feeding and dependable lockup during training sessions, tactical drills, or range recreation.
Constructed from lightweight yet durable 6061-T6 aluminum, the KCI-MZ018 features a corrosion-resistant black anodized finish with a slick exterior coating for rapid mag changes and clean drop-free releases. The body is fitted with internal ribs to minimize cartridge friction and resist feed-lip deformation under standard load stress.
Equipped with a high-tensile steel spring and a low-friction anti-tilt follower, the KCI-MZ018 provides consistent, non-binding cartridge presentation from the first shot to the last lockback. Fully compatible with .223 Rem, 5.56 NATO, and .300 Blackout ammunition, this 30-round aluminum magazine is an economical, high-performance addition to any AR-15 setup.
