A fully automatic light machine gun, the M249 SAW (A.K.A Squad Automatic Weapon) has been in service with the U.S. military for nearly three decades. The semi-automatic FN M249S is a replica of this well-known weapon.

Chambered in 5.56 NATO, it does differ from the fully automatic currently in military service that has an open-bolt configuration. The M249S only operates from a closed-bolt position in semi-auto.

FNH USA’s M249S is 40.75 inches long with a 20.5-inch barrel. The barrel is cold-hammer-forged, chrome-lined alloy-steel with a twist rate of 1:7.

The receiver is a formed steel frame with claw extractor design. The cases eject to the side with a fixed, pivoting ejector. To customize, there’s a top cover integrated MIL -STD 1913 mounting rail.

The trigger pull is adjustable from 4 to 6.5 pounds. When the gun is empty, it weighs 17 pounds. It takes a linked ammo belt as well as magazines.

It is expected to retail for about $7,999.
