Clearing the weapon is performed by ensuring that the bolt is locked to the rear and the weapon is on safe. The top cover is then lifted, the remaining belt (if any) is swept out of the feed tray, the feed tray is lifted to visually inspect the chamber and the face of the bolt. Any links or brass casings are removed. The weapon is now clear. In the extremely unlikely event that a live round is on the bolt face, it is knocked loose with a cleaning rod or another rigid object. If there is a live round lodged in the barrel, the operator must immediately decide if the barrel is hot enough that there is a chance of it cooking off. If there is, they will immediately move their face away from the opening of the weapon; and aiming the gun in a direction that is perceived to take the least amount of damage or casualties should the event of a cook-off occur. They will then wait for the barrel to cool off before attempting to remove it. They can also attempt to extract the round by closing the cover, taking the weapon off of safe, and pulling the trigger. This will likely cause the weapon to fire, so care is taken to ensure that the weapon is first pointed in a safe direction.
