FN M249S

The FN M249S brings iconic military firepower to the civilian market with a semi-automatic version of the U.S. military’s M249 Squad Automatic Weapon. Built by FN America—the original manufacturer of the M249—this rifle offers the same battle-proven design, rugged construction, and belt-fed capability in a legal, semi-auto configuration.

Chambered in 5.56×45 NATO (.223 Rem compatible), the M249S features an 18.5″ cold hammer-forged, chrome-lined barrel designed for exceptional heat resistance and long-term durability. Whether used for collection, range enjoyment, or display, it represents one of the most reliable and historically significant platforms ever produced.

This model includes two feeding options:

• Standard 30-round STANAG magazine

• 200-round belt box for full SAW experience

The M249S maintains the classic ergonomics of the light machine gun role, including the fixed stock, robust carrying handle, top cover feed tray, and heat shield. Each rifle is built to FN’s strict military-grade standards, making it one of the most sought-after collector rifles in the firearms world.

Whether you are a serious FN collector, military enthusiast, or simply want the most unique rifle available on the commercial market, the FN M249S stands in a class of its own.
