Where Do You Put the Rear Sight on an AR-15?

The rear sight on an AR-15 is mounted onto the rear of the upper receiver. It is typically secured in place by two screws or bolts. The rear sight can be adjusted for windage and elevation to help you get the most accurate shot.

Most AR-15s have a rear sight that is adjustable for both windage and elevation. To adjust the elevation-

  • Loosen the two screws that secure the rear sight to the upper receiver and rotate the rear sight up or down.

  • Adjust the rear sight of the Bushmaster AR 15 to the lowest setting.
  • Look through the rifle scope and adjust the windage and elevation turrets to center the crosshairs on the target.
  • Fire a three-shot group at the target and adjust the turrets to move the point of impact to the center of the target.
  • Move the target to 50 yards and fire another three-shot group.
  • Adjust the turrets to move the point of impact to the center of the target.
  • Repeat the process for 100 yards.
  • Adjust the elevation and windage turrets to move the point of impact to the center of the target.
  • After ensuring the rifle is sighted in from 25-100 yards, adjust the rear sight of the Bushmaster AR 15 to the desired setting.

AR-15 Sight Adjustments At 25 Meters:

To adjust the sights on an AR-15 at 25 meters, you will want to adjust the windage and elevation knobs on the rear sight. 

  • To adjust the windage, use the knob on the right side of the rear sight to move the point of impact left or right. 
  • To adjust the elevation, use the knob on the top of the rear sight to move the point of impact up or down.

After each adjustment, fire a few test rounds to check your adjustments.

Zeroing Iron Sights AR-15:

Zeroing iron sights on an AR-15 is a fairly straightforward process. 

  • First, you will need to adjust the rear sight by either turning the windage and elevation knobs or by using a sight tool to make more precise adjustments. 
  • Once the rear sight is adjusted, you will need to shoot a few rounds at a target that is 25 yards away. The goal is to get the rounds to land in the center of the target.
  • When this is done, you will need to adjust the front sight post up or down to get the rounds to hit the center of the target. 
  • After completing the adjustments, you will need to fire a few rounds to make sure that the point of aim and point of impact are the same.

But How to Zero Iron Sights Without Shooting?

Zeroing iron sights on a firearm can be done without actually shooting the gun. This process is called “bore sighting” and involves the use of a bore sighting device, such as a laser bore sighter.

  • To begin, the firearm should be securely placed in a gun vise or held with a friend’s help.
  • Next, the bore sighting device should be inserted into the muzzle of the gun and aligned with the target. 
  • The adjustment screws on the iron sights should then be adjusted until the laser beam is centered on the target. 

Once the sights are zeroed, the gun can be fired to verify the accuracy of the adjustments. This process can be repeated until the desired accuracy is achieved.

About Bore Sighting:

Bore sighting is an easy and cost-effective way to zero iron sights without actually firing the gun. It is important to note that bore sighting should not replace actual shooting; it is simply a tool to help ensure the sights are accurately aligned before shooting.

Do You Need A Front Sight On An AR-15?

Yes, the front sight is necessary on an AR15. The front sight is the part of the rifle that allows the shooter to accurately aim and line up the target with the barrel. 

It is usually placed at the very front of the rifle and can be either integrated into the design of the rifle (as is the case with the M4) or mounted separately (as is the case with the AR15). The front sight also helps the shooter to maintain their sight picture while shooting and helps them to make accurate shots.

AR-15 Front Sight Adjustment Tool

An AR-15 front sight adjustment tool is used to make adjustments to the front sight post of an AR-15 rifle. It is used to adjust the elevation and windage of the front sight post. 

The tool typically consists of a small screwdriver or hex wrench to make the adjustments. The tool can be used to make small or large adjustments depending on the rifle and the type of adjustment being made.

Point-by-Point Adjustment Procedure

  • Make sure the gun is unloaded and the chamber is clear.
  • Place the gun on a stable surface, muzzle down, and use a punch and hammer to drive out the pin securing the front sight.
