Attachments in Arc Raiders are an essential part of weapon customization that change how a gun behaves in combat. They modify stats like recoil, dispersion (shot spread), magazine size, ADS speed, and noise, letting you tailor a firearm to your playstyle. There are often blueprints for attachments that you can find during raids to help you craft.
1. What Are Attachments in Arc Raiders
Vertical Grip III attachment
Attachments are weapon modifiers you equip on guns either before or during a raid using the inventory or gunsmith bench. They slot into categories like muzzle/barrel, underbarrel (grips), magazine, and stock — each affecting a different aspect of weapon performance. Attachments can improve:
- Recoil Control: Vertical or horizontal kick is reduced, making sustained fire more manageable.
- Accuracy & Dispersion: Tightening where bullets go when firing quickly or at range.
- Magazine Size: Allows more bullets before reloads.
- Handling & ADS Speed: Stocks and grips can speed up aiming or quicken recoil recovery.
- Noise Reduction: Suppressors reduce noise for stealth play.
2. How Attachment System Works in Arc Raiders
Compensator II attachment
Arc Raiders uses a tiered gunsmith and blueprint system to unlock and craft attachments. Basic mods are available early, while more powerful versions require finding specific blueprints in raids and gathering advanced materials.
- Tier 1: Standard attachments you craft from common resources at the gunsmith (e.g., Metal Parts, Plastic, Steel Springs).
- Tier 2 & 3: Unlock after finding blueprints in missions and extracting. These often provide significant stat boosts but sometimes come with trade-offs (e.g., slower ADS time).
- Legendary Mods: Such as high-end fire rate or unique behavior enhancements like Anvil Spliter to turn it into shotgun-like shells or Kinetic Converter to boost gun speed.
Higher-tier attachments are powerful but may reduce handling or durability, forcing thoughtful choices rather than just equipping the highest number.
