HIGH CAPACITY MAGAZINE, 100 ROUND FOR .223 REMINGTON/5.6 NATO AMMUNITION, COMPATIBLE WITH M4/M16/VARIANT/STANAG 4179 COMPLIANT HOST WEAPONS
Due to tremendous demand, we are heavily backordered on our 100-round magazines.
NOTE: SureFire 60-round mags are available now. (updated 11/5/2012)
The SureFire high-capacity magazine for 5.56x45 mm (.223 Remington) ammunition, also available in a 60-round version, is compatible with M4/M16/AR-15 variants and other firearms that accept standard STANAG 4179 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. SureFire offers a heavy-duty magazine pouch specifically designed for the MAG5-100 that attaches to a MOLLE system vest.
