KCI USA KCIMZ066 AR-15 .223 Rem/5.56x45mm NATO 21rd Translucent Smoke Polycarbonate Magazine

The KCI USA KCIMZ066 is a 21-round AR-15 pattern rifle magazine chambered for .223 Remington / 5.56x45mm NATO. The body is molded from durable translucent smoke polycarbonate, giving the magazine a lightweight feel in the magwell while letting the shooter see remaining rounds at a glance through the see-through walls. An anti-tilt polymer follower feeds rounds reliably through a standard mil-spec AR-15 / M4 magazine well.

Designed as an affordable, high-capacity option for range and training use, the KCIMZ066 drops into mil-spec lower receivers and provides a practical magazine for plinking, drills, and courses of fire where quick visual round counts help avoid run-outs.
