Season 30 of Apex Legends adds a new tier of weapon mods called Corrupted Red Attachments. Each one boosts a specific weapon stat while forcing a matching penalty, so slotting one is a trade rather than a straight upgrade. There are five in total, and a gun can only hold one at a time.
Quick answer: The five Corrupted Red Attachments are the Overflowing Magazine, Headseeker Barrel, Tactical Laser, Agile Standard Stock, and Rapid Sniper Stock. Every one grants a strong buff, applies one negative stat, and only a single Corrupted Attachment can go on a weapon.
Every Corrupted Red Attachment and its effect
Each attachment pairs a headline buff with one drawback. The table below lists the positive stat, the tier its baseline improvements match, and the penalty you accept in return.
| Attachment | Buff | Drawback |
|---|---|---|
| Overflowing Magazine | Magazine size beyond a Purple Magazine; fits any weapon that accepts a magazine | Reduces reload speed |
| Headseeker Barrel | Higher headshot damage; recoil control at Purple Barrel level | Reduces hipfire accuracy |
| Tactical Laser | Faster reload; hipfire accuracy at Purple Laser Sight level | Reduces ADS recoil control |
| Agile Standard Stock | Removes the move speed penalty, adds ADS move speed, and matches Purple Standard Stock reload and handling | Reduces magazine size |
| Rapid Sniper Stock | Higher rate of fire; reload and handling at Purple Sniper Stock level | Reduces magazine size |
How the one-per-weapon limit shapes your loadout
You can equip only one Corrupted Attachment on a given weapon, so you cannot stack multiple buffs into a custom super-gun. That limit turns each pickup into a decision about what your weapon should do best.
The Overflowing Magazine is the clearest example. Fitting it to an SMG like the R-99 pushes ammo capacity past Purple tier, which makes one-clipping at close range easier, but the longer reload makes the gun feel more like an LMG. The Agile Standard Stock pulls in the opposite direction, adding movement speed and ADS mobility at the cost of a smaller magazine.
Because every option carries a penalty, these mods reward matching a weapon to a role rather than chasing the next color up the rarity scale.
Where to find Corrupted Red Attachments
These attachments sit above the standard rarity tiers and appear more often as a match goes on, so they show up as an endgame consideration rather than an early-game find. You can pick them up from the following sources.
- The core loot pool, with a low spawn chance from any loot crate
- Round 2 and Round 3 care packages
- High-tier loot locations such as the World’s Edge Vaults and the Icarus Ship Bridge
Reading the stat trade before you commit
Season 30 shows exact numbers when you inspect an attachment. Attachment loot cards display the precise stat change that will apply once the mod is equipped, so you can see the gain and the penalty before you swap. That makes it possible to judge whether a Corrupted Red Attachment fits your weapon and playstyle instead of guessing.
Marked goes live on August 4, 2026, and the full breakdown of these mods sits in the official Marked game updates from Respawn. Once you find one, the loot card confirms the change, and the equipped stat shift will be visible on the weapon.
