Surefire may be well known for their illumination products, but they will soon be recognized just as well for their extended capacity magazines for the AR15 modern sporting rifle family of rifles. The Surefire 60rd and 100rd extended capacity magazines are far superior to the 100rd drum style of mags due to being made to mimic standard milspec magazines in look and geometry. Made from milspec hard anodized aluminum, the Surefire 60rd magazine is slightly thinner than 2-30rd mags taped together and just slightly longer which allows the shooter to still maintain a proper shooting grip which is impossible with cumbersome drum style mags. The non-binding coil springs are long lasting and cadmium coated for low friction and the ingenious nesting followers help make the Surefire 60rd magazine far more reliable than other extended capacity magazines. The Surefire 60rd mags will fit in most standard double mag pouches so you won't have to buy any special carriers for your mags. The Surefire 60rd magazines will fit any STANAG compatible firearm, for a variety of different firearm uses.
