FN M249 SAW Barrel Assembly – 5.56 NATO with Carry Handle

This is an original FN M249 SAW (Squad Automatic Weapon) barrel assembly, chambered in 5.56x45mm NATO. The assembly includes the quick-detach barrel, flash hider, gas block, front sight base, and ribbed polymer carry handle. Marked with U.S. military contract numbers (19200 ASSY), this barrel is an authentic GI part, designed for rapid changes in the field to prevent overheating during sustained fire.

The barrel retains its parkerized finish with light handling wear and some patina on the gas block. The flash hider and front sight post are intact, and the quick-change latch functions as intended. Whether you’re sourcing a replacement barrel for an M249, building a legal semi-auto clone, or adding to a collection of U.S. military parts, this is a desirable and functional component.
