Frequently Asked Questions

What is the FN M249S and how does it differ from the military M249 SAW?

The FN M249S is the semi-automatic, civilian commercial version of the military's M249 SAW (Squad Automatic Weapon). While sharing many components, the M249S is designed for semi-automatic fire only and is manufactured to comply with US civilian firearm laws.

How is ammunition loaded into the FN M249S?

Ammunition can be loaded via a disintegrating belt, typically fed from a belt holder bracket. The process involves ensuring the belt is correctly oriented (brass down, links up) and placed onto the feed tray before charging the weapon.

Can the FN M249S use standard rifle magazines?

Yes, the FN M249S is designed to accept standard STANAG magazines, similar to those used in AR-15 platforms. It also functions with drum magazines like the Magpul D60, though this can affect balance.

What is the significance of the FN M249S being US-made?

Being manufactured by FN in Columbia, South Carolina, means the M249S is entirely US-made. This avoids firearm import laws and ensures compliance with ATF regulations for civilian ownership.
