Manufacturer: SureFire MAG5-100Item: 2-MGSFMAG5-100UPC: 084871315821The SureFire high capacity magazine for 5.56x45 mm (.223 Remington) ammunition is compatible with M-4, M-16 and AR15 variants and other firearms that accept STANAG 4179 (standard M16) magazines. Constructed from Mil-Spec hard-anodized aluminum, they feed smoothly and reliably due to optimal geometry, non-binding coil springs, and ingenious nesting polymer followers. The long-lasting springs are cadmium coated for low friction and excellent corrosion resistance. Magazines require no lubricants and can be easily disassembled without tools for cleaning.
SureFire High capacity magazines provide distinct tactical advantages: increased initial firepower in ambush situations; fewer reloads overall, which means less downtime and target distraction in a firefight; fast and easy magazine insertion, even with a closed bolt; less bulk compared to drum mags, enabling a normal weapon grip.
The SureFire 100 round magazine is slightly thinner than two 30 round magazines clipped together and is about the same overall length. The SureFire 100 round magazine fits in most dual magazine pouches, eliminating special carry pouches required for drum magazines.
