ZEROING THE ASSUALT RIFLE

 

Zeroing the Assault Rifle

Zeroing refers to the process of adjusting a firearms sight so that the point of aim aligns with the point of impact at a specific distance. This ensures that when you aim at a target, the bullet will hit precisely where intended, typically at a pre-determined range for example 25, 50, 100 meters. Zeroing is essential for accuracy in shooting, whether using iron sights, red dots, or scopes.

A.    Set the Range:

The standard zeroing range for an M 16 is typically 25 meters or 50 meters. This means you will adjust your sights so that the bullet will hit where you are aiming at the distance. A 25 meter zero often corelates with an effective zero at 300 meters due to the trajectory of the bullet.

 

B.     Prepare the Rifle:

·   Load a magazine: Ensure the rifle is unloaded and follow safety protocols before handling it.

·      Set your sights: For an M 16, there are two types of iron sights rear sight aperture and front sight post.

·      Rear sight Aperture: Set this to the Z mark or small aperture for long ranges such as 500 meters. Use the large aperture for shorter ranges.

·        Front Sight Post: This is used for elevation adjustments.

·        Rear sight Drum: Adjust for windage (Left-right adjustments)

 

C.    Establishing a Stable Firing Position:

·        Prone Position: Lay down in the prone position to create stability.

·    Sandbag or Bipod: Use a sandbag or bipod if available to rest the rifle and reduce movement.

 

D.    Use a Target Designed for Zeroing:

·     Use a standard M 16 zeroing target, which has a grid pattern for easy sight adjustment. The target will typically have a silhouette or bull’s eye for aiming. And position the target at 25 meters or 50 meters, depending on your zeroing preference.

 

E.     Fire a Three-Round Group:

·        Aim at the centre of the target, ensuing your point of aim is aligned with the canter.

·        Fire a three-round group while maintaining the same point of aim for all shots.

·      After firing, observe where the group of shots hit the target. They may be off – Centre due to misaligned sights.

 

F.     Adjusting the Sights:

·        Use your shot group to determine how to adjust the sights:

·        Elevation Adjustment (UP/Down): Use the front sight post.

a)   If the shots hit low, turn the front sight counter clock wise to rise the point of impact.

b)     If the shots hit high, turn the front sight clock wise to lower the point of impact.

·        Windage adjustment (Left-Right): Use the rear sight drum.

·        If the shots hit left, turn the windage knob to move the rear sight aperture to the right.

·        If the shots hit right, turn the windage knob move the rear sight aperture to the left.

·    Front sight post: One click = 1.2 inches MOA (Minute of angle) = 0.6 inches at 50 meters.

 

G.    Repeat the Process:

·     After making sight adjustments, fire another three round group using the same point of aim.

·     Check where the group lands and continue adjusting until your group hits the center of the target, where your point of aim and point of impact align.

 

H.    Confirm Zero at Distance:

·    Once you have zeroed at 25 or 50 meters, confirm your zero at 100 or 300 meters by engaging targets at those distances to ensure the point of aim matches the point of impact at extended ranges.

·      Once your sight is correctly zeroed, mark the position of the sight settings such as number of clicks on the rear sight drum). This way, you can easily return to your zero settings later if needed.

·    Always fire in consistent, stable positions for the best accuracy. Ensure your rifle is properly maintained (clean barrel, correctly lubricated) for reliable zeroing.
