ARC Raiders Lightweight Stock Blueprint Guide

The Lightweight Stock is an Epic weapon modification in ARC Raiders. It focuses on faster handling, improving how quickly a weapon aims, equips, and swaps. However, these benefits come with clear recoil trade-offs, making it a situational choice rather than a universal upgrade.

What the Lightweight Stock Does

The Lightweight Stock is designed for players who value speed and responsiveness in close- to mid-range fights.

Stat Effects

EffectValue
ADS Speed+200%
Equip Time−30%
Unequip Time−30%
Vertical Recoil+50%
Recoil Recovery Time+50%

In practice, this means faster reactions and smoother weapon swapping, but noticeably worse recoil control during sustained fire.

Compatible Weapons

The Lightweight Stock can be installed on a wide range of weapons, including:

This broad compatibility makes it useful across multiple loadouts.

How to Get the Lightweight Stock Blueprint

The Lightweight Stock is blueprint locked, meaning you must unlock the blueprint before crafting it.

Available Methods

  • Scavenging – The blueprint can be found while looting during raids.
  • Crafting – Once unlocked, you can craft the mod at the Gunsmith.

Scavenging remains RNG-based, so some players may take longer to unlock it.

Crafting the Lightweight Stock

After learning the blueprint, the Lightweight Stock can be crafted with the following requirements.

Crafting Requirements

IngredientsRequirementsResult
2× Mod ComponentsGunsmith Level 31× Lightweight Stock
5× Duct TapeBlueprint required 

The material cost is moderate, making it accessible once Gunsmith Level 3 is reached.

For players who want to save time and avoid the uncertainty of RNG, some choose to Buy Arc Raiders Lightweight Stock blueprints from U4N. It’s simply an alternative for those who prefer to focus on crafting and testing builds instead of repeated scavenging runs, especially once Gunsmith Level 3 is already unlocked in ARC Raiders.

Where to Get the Lightweight Stock

There is no single fixed map location where the Lightweight Stock always appears. Instead, it is obtained through the game's normal loot and progression systems.

Blueprint Drops

The most reliable way to unlock the Lightweight Stock is by finding its blueprint. Once learned, you can craft the attachment whenever you need it.

Blueprints can come from:

  • High-tier loot containers and weapon cases
  • Mission and contract rewards
  • Stronger enemies and elite encounters
  • Vendors, depending on progression and availability

Blueprint spawns are not guaranteed. They rotate between runs and locations, so exploring high-value areas consistently is important.

Direct Loot

In some cases, the Lightweight Stock itself can drop as a ready-made attachment from higher-quality loot containers. This lets you use it immediately, but it does not unlock crafting unless you also obtain the blueprint.

How to Use the Lightweight Stock

Choose the Right Weapons

The Lightweight Stock works best on weapons that benefit from faster handling, such as:

  • Weapons with slow ADS speed by default
  • Builds focused on quick reactions and close-to-mid-range fights

It is less suitable for weapons where stability and sustained fire are more important.

Understand the Trade-Off

While the faster ADS and handling feel strong, the increased recoil is very noticeable. Shots climb upward faster, and the weapon takes longer to settle after firing.

This attachment rewards controlled, deliberate shooting rather than long bursts.

Improve Recoil Control

To use the Lightweight Stock effectively:

  • Fire in shorter bursts
  • Actively pull down to counter vertical recoil
  • Practice recoil control before taking it into high-risk runs

Combine With Other Attachments

Some players pair the Lightweight Stock with attachments that help manage recoil. This helps balance the handling speed with better control.

Recycling and Salvaging

If you no longer need the mod, it can be broken down for resources.

MethodMaterials Gained
Recycling1× Mod Components, 1× Duct Tape
Salvaging2× Mechanical Components

Salvaging is usually the better option if you need Mechanical Components.

Is the Lightweight Stock Worth Using?

The Lightweight Stock works best for aggressive playstyles and weapons used in short engagements. It shines when quick aiming and fast swaps matter more than recoil control. For longer-range fights or sustained fire, the recoil penalties can outweigh the benefits.

In general, this mod is most effective when paired with recoil-stabilizing attachments or used on weapons already known for manageable recoil.
