Government Export Restriction

The SureFire MAG5-100 High-Capacity 100 Round Magazine for 5.56x45mm (.223 Remington) ammunition is compatible with M4/M16/AR15 variants and other firearms that accept standard STANAG 4179 magazines. Constructed from MIL-SPEC hard-anodized aluminum, it feeds smoothly and reliably due to optimal geometry, non-binding coil springs and ingenious nesting polymer followers. It requires 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 in a fire fight; fast and easy magazine insertion, even with a closed bolt; less bulk compared to drum magazines, enabling a normal weapon grip. The 100-round magazine can be carried in an optional nylon pouch that attaches to a MOLLE system vest.

  • MIL-SPEC hard-anodized Aluminum construction
  • Compatible with all weapons that accept standard STANAG 4179 compliant magazines
  • Easily seated in weapon with bolt forward

  • Only 1.66" thick, less that two 30-round magazines clipped together
  • Fits in optional MOLLE compatible pouch (NOTE: Pouch NOT INCLUDED)
  • Made in the USA
