Where to find the Extended Shotgun Magazine III Blueprint

There's no fixed, guaranteed “one single spot” that always has this blueprint. Blueprints in Arc Raiders spawn randomly in loot containers around the maps. But players have shared several reliable ways and places where rare blueprint drops – including high‑tier weapon mod blueprints like Extended Shotgun Magazine III – can spawn.

1. Search High‑Loot Areas

There are certain locations on popular maps where valuable loot and higher‑tier blueprints are more likely to appear:

  • Loot containers in major map points like dam structures, abandoned buildings, and control rooms. These areas often have weapon crates, backpacks, or secured containers that can drop blueprints.
  • Security Lockers (where available) tend to have better blueprint spawns. Arc Raiders community guides list these as higher‑chance spots in multiple mission areas.

2. Complete Night Runs

Many players report that night raids (missions played at night) increase the overall loot quality, which seems to include blueprint drops. Running the same loop repeatedly during night missions can improve your chances of finding rarer items.

3. Kill Certain Enemies / Destroy Surveyors

Community posts note that Surveyor ARC enemies (the floating recon units) sometimes drop rare blueprints when destroyed. It's not guaranteed, but it's a known additional source of higher‑tier loot, including magazines and grips.

4. Loot Everything You Can

Practically:

  • Open every crate, backpack, and weapon cache you find.
  • Don't skip rooms that feel “off the path” — blueprints often spawn in less obvious containers.
  • If you find locked containers, prioritize getting the key so you can open them; they can contain blueprints that don't have fixed spawn locations elsewhere.

Recycling & Salvaging the Extended Shotgun Mag III

If you no longer need the Extended Shotgun Mag III, you can recycle or salvage it to gain useful materials:

Recycling: Recycling the Extended Shotgun Mag III yields:

  • 1x Mod Components
  • 2x Steel Spring

Salvaging: Salvaging the Extended Shotgun Mag III gives you:

  • 2x Mechanical Components

Using the Blueprint

Once you pick up the Extended Shotgun Magazine III blueprint:

  1. Return to your Raider Den or a safe area.
  2. Go to the Gunsmith III bench. This is the workshop level required to unlock and craft this magazine.
  3. Learn the blueprint by selecting it from your inventory and choosing “Learn and Consume”.
  4. After learning it, gather the crafting materials (typically Mod Components and Steel Springs) and craft the magazine when needed.

Tips for Success

  • Prioritize missions and routes with lots of loot containers. The more things you open, the more chances you have at a rare blueprint.
  • Make a mental note of which areas you've already checked. Blueprint spawns aren't fixed, so revisiting high‑chance spots is often worthwhile.
  • Don't worry if it takes multiple runs. Blueprint drops are inherently random, and persistence tends to pay off more than any one “perfect route.”

Summary

  • Extended Shotgun Magazine III is a high‑tier shotgun magazine upgrade blueprint you must unlock at a Gunsmith III bench.
  • There's no single guaranteed spawn location for it. Instead, you find it from random loot containers in loot‑rich areas across maps.
  • Night missions, thorough looting, and checking high‑value areas improve your chances overall.
  • Once you find the blueprint, learn it and craft at the Gunsmith III bench using the required materials.

The Extended Shotgun Mag III is a great asset for anyone who wants to make their shotgun more efficient by increasing its ammo capacity. Whether you prefer scavenging for blueprints or crafting them, the modification is worth adding to your arsenal.
