Standardized rail-mounted backup iron sights designed for M4-A1 assault rifle. — In-game description

The Backup Iron Sights is a non-magnifying, iron sight for the M4-A1 in DayZ Standalone. Although it is intended for use with the M4-A1, it can also be attached to the SG5-K, USG-45 and LAR. Since it provides no performance improvements or magnification and is intended only as a backup, attaching the Backup Iron Sights to these weapons is not recommended.

Trivia[edit | edit source]

  • Before 1.03, the Backup Iron Sights was named the BUIS.
  • The BUIS was temporarily not spawning in patches 0.63 to 1.02, awaiting reimplementation.
  • At one point, it was possible to equip the BUIS sights to the Crossbow. This ability was later removed.
  • This model is based on the MaTech BUIS which is currently the standard issue M4 rear iron sight for the U.S. military.
