6.2. Failure to Fire (Hot Rifle) Trigger is pressed, hammer falls, the rifle does
not fire.
1. Keep the muzzle pointed down range, place the rifle on SAFE, remove the magazine, if you cannot extract the loaded
cartridge within ten (10) seconds you must wait a minimum of 15 minutes before handling the rifle.
2. Upon completion of the 15 minutes, retract the charging handle all the way back and observe the ejection of the
cartridge; and
3. Visually inspect the chamber for any obstructions, if the chamber shows to be clear, release the charging handle to
feed a new cartridge. DO NOT ride the charging handle forward.
4. Attempt to fire the rifle again.
If the rifle does not fire after completing 6.1 or 6.2:
1. Unload, and clear the rifle.
3. Cycle the bolt assembly chambering a round; and
2. Insert a fresh magazine; 4. Attempt to fire the rifle.
If the rifle fails to fire after attempting all of the above, the rifle should be returned to SIG SAUER, Inc. for evaluation by a
factory trained technician.
WARNING:
EXCESSIVE HEAT BUILD UP IN THE CHAMBER CAN CAUSE WHAT IS REFERRED TO AS A “COOK OFF”. THIS MEANS THE
HEAT IN THE CHAMBER CAUSES THE POWDER TO IGNITE IN THE CHAMBERED CARTRIDGE. THE ROUND THEN DETONATES
JUST AS IF IT WERE FIRED. IF THE RIFLE HAS BEEN FIRED FOR AN EXTENDED PERIOD OF TIME FOLLOW THE STEPS IN 6.2.
