Things You'll Need
Instructions
Point your rifle in a safe direction. This should always be a concern when handling a weapon. Even if you think a weapon is unloaded, you should only point it away from people.
Cock your weapon. Pull the charging handle all the way back and hold it. With the charging handle back, turn the weapon on its side and look into the firing chamber. Make sure there are no bullets caught in the chamber. If there are, they can cause an explosion when you put the fresh bullets in.
Ride the bolt forward. Slowly, keeping pressure on the charging spring, return the bolt to the forward position. Letting the bolt slam forward, even though it sounds cool in movies, is hard on the bolt mechanism.
Move the selector lever by your right thumb to "SAFE." You can't put the M16 on "SAFE" unless it is cocked. That is why you have to cock and clear it before putting it on "SAFE."
Insert a loaded magazine into the magazine well, below the trigger. Push the magazine up from the bottom until the catch engages. Slap the bottom of the magazine up into the weapon to ensure that it stays. Pull down on the magazine once it is in place to see if it will slip out.
