Here is a step-by-step guide on how to shoot an AR-15:

1. Putting the magazine in: Once you have a fully loaded magazine, pick up the rifle by the pistol grip in your good hand. Grab the fully loaded magazine with your off hand. Make sure the ammo in the magazine is pointed in the same direction as the rifle.

2. Chambering a round: Pull back on the charging handle located on the top of the rifle. Release it and let it go forward. This will load a round into the chamber.

3. Identifying your sights: The AR-15 has two types of sights: iron sights and optics. Iron sights are located on top of the rifle and are used for aiming at targets. Optics are scopes that can be mounted on top of the rifle.

4. Using optics: If you are using optics, adjust them so that they are properly aligned with your eye.

5. Using Iron Sights: If you are using iron sights, line up your front sight post with your rear sight aperture.

6. Line up your shot: Once you have identified your sights, line them up with your target.

7. Shooting: Take a deep breath and exhale halfway. Squeeze the trigger slowly until it fires.

Remember to keep the AR-15 on safe and your finger away from the trigger until you're ready to shoot. When you're on target, flip the fire/safe selector straight up to "fire." Whenever you come off the gun and stop shooting, return the firearm to safe .
