Addendum is meant to replace those sections of the Operator’s Manual, which is also included with your rifle.

This Safety Addendum must be read and fully understood before handling or firing your FN M249S® and must

remain with the rifle and Operator’s Manual, even when transferred to a new owner.

Any sections of the Operator’s Manual not discussed in this Safety Addendum remain unchanged and are

applicable.

WARNING! BEFORE HANDLING, INSPECTING, OR FIRING THE FN M249S®, FULLY READ AND

UNDERSTAND COMPLETELY THE OPERATOR’S MANUAL AS WELL AS THIS SAFETY ADDENDUM.

ALWAYS KEEP THE MUZZLE POINTED IN A SAFE DIRECTION. FAILURE TO FOLLOW THESE WARNINGS

MAY RESULT IN SERIOUS INJURY OR DEATH.

In order to “lock” or hold the bolt to the rear-open position, a manual bolt lock device is included.

To use the manual bolt lock device to hold/lock the bolt in the open position: 1.

If shooting is imminent, a cartridge can now be moved from the feed tray to the chamber by slowly pulling back on the charging handle and releasing it.
