The SureFire High-Capacity Magazine is compatible with all Mil Spec AR-15 variants and other firearms that function with standard AR-15 pattern magazines.
Constructed entirely from Mil-Spec aluminum and then Type III hard coat anodized for durability. Surefire magazines feed smoothly and reliably were designed to be left loaded indefinitely.
Additionally, Surefire Magazines can be disassembled for cleaning via the removable floorplate.
Also, unlike other high capacity magazines, the Surefire High-Capacity Magazines DO NOT require dry lubricants for reliability.
Due to their unique 4×2 quad stack configuration, the magazines add firepower without excessive bulk.
The 60-round magazine is only an inch and a half longer than a standard 30 round magazine and narrower than two 30-round magazines clipped together.
Surefire High-Capacity Magazines can be seated in a rifle with a closed bolt, even when fully loaded-no downloading required. Surefire ensured this by allowing for differing tolerances between SAAMI and NATO specifications.
