Discontinued by Surefire
The hard-to-find Surefire 100 round .223 5.56mm for AR-15, SA80 and STANAG format rifles.
Functioning the same way as standard AR magazines the mil-spec aluminium design is hard coat anodized for a very durable finish.
Using their patented 4x2 quad stack design the magazines offer a high capacity without the weight and bulk of a drum mag. They measure only 5 inches longer that a standard 30 round magazine and still narrower than x2 30 round magazines clipped together.
Can be inserted on a closed bolt. The springs can be left loaded indefinitely. Ideal for LSW use.
