Line 10: Line 10:
Iron sights work by providing and advocating a horizontal and vertical reference point that allow the shooter to actually align the gun parallel to the shooter's line of sight and crosshair. Once the sights are precise with each other, they are placed in correct relation to the target. This places the gun at a precise angle to the line of sight to the target. With appropriate compensation for range to the target, parallax between the iron sights and the gun's bore, and the trajectory of the projectile, a shot fired will hit the target.

The proper method of adjusting an iron sight on a weapon.

The iron sight is a open, unmagnified system used to assist the aiming of typically firearms. Several weapons, such as the M7 Caseless Submachine Gun and M90 Close Assault Weapon System, utilizes an iron sight, however other UNSC weapons, e.g. the MA5B and MA5C Assault Rifle's, the Machine Gun Turret, and some M6 handguns do not seem to use them for reasons unknown.

Operation and Adjustment

Iron sights work by providing and advocating a horizontal and vertical reference point that allow the shooter to actually align the gun parallel to the shooter's line of sight and crosshair. Once the sights are precise with each other, they are placed in correct relation to the target. This places the gun at a precise angle to the line of sight to the target. With appropriate compensation for range to the target, parallax between the iron sights and the gun's bore, and the trajectory of the projectile, a shot fired will hit the target.

Since the eye is only capable of focusing on one plane, and the rear sight, front sight, and target are all in separate planes, only one of those three planes can be in focus at one time. Which plane is in focus depends on the type of sight, and one of the challenges to a shooter is to keep the focus on the correct plane to allow for best sight alignment. A tiny error in sight alignment can be multiplied hundreds or thousands of times by the time the projectile reaches the target.
