Where to find Extended Light Mag III

Unlike basic attachments that you can find randomly from loot or buy from shops, Extended Light Mag III usually needs a blueprint first. Once you have the blueprint, you can craft the item at the Gunsmith bench.

1. Find the Blueprint

Extended Light Mag III is blueprint‑locked. You must first obtain the blueprint before you can craft the mod.

Blueprints in Arc Raiders come from:

  • Scavenging locations during raids — rare loot containers, weapon cases, elite enemy drops, or supply crates.
  • Random drops on maps — there isn't a fixed coordinate, and drop rates are relatively low for rare blueprints, so repeated runs help.
  • Blueprint farming routes — certain maps like Dam Battlegrounds and Buried City are commonly mentioned by players as good areas to check for rarer blueprints.

There is no definitive published list of exact spawn points for the Extended Light Mag III blueprint, which means you'll need to search and loot frequently and thoroughly.

Community threads confirm that blueprints like Extended Light Mag III do show up in normal scavenging loot — they just aren't everywhere, and players sometimes trade them.

Tips for Finding the Blueprint

There isn't a single set location you can go to for this blueprint, but a few general principles help:

1. Run High‑Loot Maps Often
Maps with dense loot (like Dam Battlegrounds and Buried City) tend to yield more rare blueprints per hour of play.

2. Loot Every Container
Weapon crates, rare supply boxes, and special containers have a better chance to drop blueprints. Thorough scavenging beats rushing.

3. Increase Gunsmith Level
Some blueprints may require you to reach Gunsmith level 3 before they're even craftable, even after you find them. Level your workshop by collecting and turning in materials so you unlock crafting.

4. Trade With Other Players
In multiplayer or community trading channels, players sometimes offer rare blueprints in exchange for other items. This isn't part of the core game systems, but it's a social way players fill gaps in their crafting lists.

Recycling & Salvaging

If you decide to recycle or salvage the Extended Light Mag III, here's what you can get:

Recycling Results:

  • 1x Mod Components
  • 2x Steel Spring

Salvaging Results:

  • 2x Mechanical Components

This makes it easy to reclaim some of the materials if you decide to dismantle the modification.

Summary

Extended Light Mag III is a valuable late‑game weapon mod that increases light weapon magazine size. Getting it involves:

  • Finding its blueprint during scavenging or rare loot runs.
  • Crafting it at a Gunsmith bench once you learn the blueprint.
  • Attaching it to compatible weapons to increase ammo capacity.

The Extended Light Mag III is a valuable modification that significantly improves your weapon's effectiveness by increasing the ammo capacity. Acquiring this blueprint can be done either through scavenging or crafting, and it requires certain materials and a high level of Gunsmithing. With its wide compatibility and strong benefits, this modification is a great choice for players looking to improve their weapon performance.
