Iron sights are aiming aids built into most firearms. Common to all designs is a front element near the muzzle opening, and a rear element at the rear of the barrel or above the weapon's action.
Two common classes of sights include open sights, which use a notch at the rear, and aperture sights, where the user looks through a ring or opening in a rear panel. Leaf sights are another type that feature graduated markings along a folding panel at the rear to assist with long-range targeting.
Battlefield 2 and Battlefield 2142Edit
Battlefield 2 is the first Battlefield game to feature iron sights. Many weapons ranging from carbines to pistols are equipped with them. Other weapons are equipped with short-range sights or long-range scopes.
In Battlefield 2142, only pistols use iron sights. Shotguns do not have optics mounted, but they do not permit aim down the sight.
Battlefield: Bad CompanyEdit
In Battlefield: Bad Company, iron sights could be used on all assault rifles, light machine guns, and pistols. Player characters are not able to use iron sights with short-ranged weapons such as the shotguns and compact assault rifles, instead using the aim feature increased zoom and brought the weapon closer to the player's face; however it would still use the circular crosshair, similar to Battlefield 1942.
In Battlefield 1943, only the rifleman's rifle, the scout's pistol and the infantry's recoilless rifle can use iron sights. The submachine guns in the game use the same aiming mechanic as in Battlefield: Bad Company.
Battlefield: Bad Company 2Edit
In Battlefield: Bad Company 2, all of the Engineer's, Assault, and Medic's weapons (excluding the MG36 and shotguns) use iron sights. Aiming down the iron sights increases the player's accuracy compared to hipfire. The player can opt to use a 4x Optical Sight or a Red Dot Sight on certain weapons instead.
All weapons in Battlefield 3 can be used with iron sights. Using the iron sights gives the shortest aim down sight (ADS) time, with only hipfire offering faster response. Equipping a sight or scope increases the time needed to ADS.
All firearms can be used with iron sights. A special sort of iron sight called the Improved Iron Sights is available for all sidearms.
Battlefield 1 Edit
There variants of the iron sights are available, the default sight, the shotgun rib and the buckhorn sight. The buckhorn sight has improved visibility but decreased view frame, and the shotgun rib is an iron sight that, as the name implies, is only available on shotguns.
- In Battlefield 4, a persistent bug occurs on Xbox 360 and PlayStation 3 in which the iron sights of most weapons do not render correctly for a few seconds after spawning, making it difficult to aim with until they load.
