FN Box Magazine FN M249, M249S 5.56x45mm NATO 200-Round with 500 M27 Links

The FN Box Magazine for FN M249/M249S 5.56x45mm NATO is a factory-original 200-round ammunition storage and feed solution engineered for shooters who rely on the M249 platform. If you operate an M249, M249S, or similar weapon system and need reliable ammo packaging that matches your rifle's design, this FN-branded box combines authentic OEM construction with practical capacity for range sessions, training, or field use.

This box comes loaded with 500 new M27 links—the standard belt-link ammunition connectors for the M249's open-belt feed system. Unlike improvised storage, purpose-built ammo boxes protect rounds from environmental damage while keeping your ammunition organized and ready to link up. The 200-round capacity strikes a balance between portable quantity and manageable weight, making it practical for transport between shooting locations without excessive burden.

FN's original packaging ensures you're getting factory-spec construction and materials designed to work seamlessly with your M249 or M249S. For competitive shooters, military/law-enforcement trainers, or dedicated .mil-spec platform users, having a reliable box and fresh links on hand eliminates improvisation and keeps your setup authentic to the weapon system's design intent.
