How Blueprint Drops Work in ARC Raiders

Before we talk about where to find this specific blueprint, it helps to understand how blueprints generally spawn in the game:

• Blueprints drop randomly from loot containers, weapon cases, and certain enemy loot caches you find during raids.
• They are not tied to a specific menu reward or preset spot like story items. You have to open containers in the world.
• Higher‑risk areas and rare loot zones generally have better chances at blueprints, but drops are still RNG.

Once you pick up a blueprint in the world, you need to learn and consume it in the menu before it unlocks the crafting recipe at your Workshop.

Where to Find Extended Medium Mag III

There is no single guaranteed “fixed” spot where the Extended Medium Mag III blueprint always spawns. Instead, players have found it while looting containers and equipment cases in certain areas:

Common Sources Where Players Have Found It

• Surveyor Caches: Community reports indicate that the Extended Medium Mag III blueprint has dropped from Surveyor loot caches you encounter during raids. These are random containers you can find in the world.

Because of the way loot works in ARC Raiders, you won't always see this blueprint even if you visit the same location multiple times. Expect to do a number of runs before finding it.

Tips For Increasing Your Chances

• Run high‑loot zones: Areas with more locked rooms, weapon crates, and rare containers boost overall blueprint drop odds.
• Play night or high‑difficulty raids: Many players report higher blueprint frequencies under more challenging conditions (though results vary and this is not formally confirmed by data).
• Check locked rooms and rare chests: These often hold better loot tier containers than open crates.

Recycling & Salvaging

If you need to dismantle an Extended Medium Mag III, you can recycle or salvage it:

Summary

• Extended Medium Mag III is a rare magazine upgrade blueprint.
• You unlock it by looting surveyor caches and other containers while raiding.
• There's no guaranteed fixed location — your best option is to loot high‑tier containers in multiple runs.
• Learn and consume it at your Workshop, then craft it with mods and springs.

The Extended Medium Mag III is an excellent upgrade for players looking to enhance their weapon's ammo capacity. By crafting it or scavenging the blueprint, players can make a significant improvement to their combat effectiveness.
