Attachment Scores Explained

Primary, Secondary and Tertiary Stat Scores:
The average percentage of all stats found in either the primary, secondary or tertiary tiers on the attachment being compared.

Overall Attachment Score:
The average percentage of all stats found in ALL of the primary, secondary AND tertiary tiers combined with contribution multipliers considered:
- Primary contributions are 100% of the average primary stat value on the attachment.
- Secondary contributions are 25% of the average secondary stat value on the attachment.
- Tertiary contributions are 5% of the average tertiary stat value on the attachment.
With contribution multipliers applied, the total average of the tiers is then divided by the the total of the contribution multipliers.
As you can see above, the total is 130%(1.3), giving us the Overall Attachment Score.

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.
