How Corrupted Attachments Work in Apex Legends Marked
Corrupted Attachments are Marked loot choices with meaningful tradeoffs; compare the live item text against your weapon's current role before equipping one.
Answer first
Quick Answer
Read the Corrupted Attachment's benefit and drawback before equipping it. Take it only when the benefit supports your weapon's range and job, then fire a short test burst before committing to the next fight.

Corrupted does not mean automatic upgrade
EA introduced Corrupted Attachments as a defining Marked loot system. Their value is contextual: the visible upside must be weighed against the visible downside and the weapon's role in your two-gun loadout.
A fast keep-or-skip rule
Keep it when the upside improves the fights you intend to take and the drawback does not break the weapon's reliable job. Skip it when it duplicates your other gun, harms your required engagement range, or changes handling you cannot test before combat.
FAQ
Should I follow a permanent attachment tier list?
Not without checking the live patch and tooltip. Attachment balance can change during a season, while the decision method remains useful.
