BUIS Sights


The BUIS, or Back Up Iron Sights, only attaches to the M4A1 in the optic/sight attachment slot. This means it can't be used as an iron sight in addition to having an optic attached.

About DayZ Weapon Attachments

Weapon attachments in DayZ can also impact weapon stats significantly, adding an element of customisation when selecting your weapon loadout.

DayZ Attachments vary a lot, but can be categorised into 6 different weapon attachment categories. These include Optics/Sights, Muzzles, Buttstocks, Handguards, Other and Magazines.

A single DayZ Weapon Attachment won't make much of a difference to your weapon unless it's an optic for improving weapon zeroing, or a muzzle for reducing your weapon sound.
