Quick answer

The Backup Iron Sights are a non-magnifying iron sight attachment for the M4-A1 assault rifle in DayZ. They are intended as a backup sight rather than a performance upgrade, providing no dispersion improvement and no magnification. They are less obstructive than the M4-A1 Carry Handle Sights, but because they only work on the M4-A1 and provide no stat benefit, they are mostly useful when you do not have a better optic available. They take 1 inventory slot, weigh 644 g, have 0 absorbency, and can be found in military loot locations as a very rare optic attachment.
