In ARC Raiders, surviving the harsh topside world requires fire power, and building that firepower requires serious crafting materials. If you are trying to piece together hard-hitting weapons like the Hullcracker or the Vulcano, you’ve likely hit a roadblock: Heavy Gun Parts.

These aren’t the kind of items you stumble across in every rusty trash can. To reliably keep your arsenal stocked, you need to know how to refine them, where to hunt for them, and how to work the economy to your advantage. Here is the complete breakdown on how to get your hands on Heavy Gun Parts, backed by the exact in-game numbers and mechanics.

The Base Formula: Heavy Gun Parts Recipe

The most reliable way to secure Heavy Gun Parts is to make them yourself back at Speranza. To do this, you need to use the Refiner II station.

The exchange rate is straightforward:

• 4× Simple Gun Parts → 1× Heavy Gun Part

While Simple Gun Parts are incredibly common (weighed at a manageable 0.5 kg each, just like their heavy counterparts), hoarding them is essential. Because of the 4-to-1 ratio, crafting enough components for a high-tier weapon requires a massive volume of basic scrap. For example, crafting a Hullcracker I requires 3 Heavy Gun Parts, which translates to a prerequisite of 12 Simple Gun Parts just to run through the refiner.

🛠️ Unlocking the Blueprint

You cannot simply walk up to Refiner II and start converting your junk. The recipe is locked behind a permanent Heavy Gun Parts Blueprint.

To unlock it naturally, you have to play the extraction loop. The blueprint is a rare, random drop found exclusively in high-tier topside loot containers. Your best bets are:

• High-tier weapon cases

• Grenade tubes

• Raider caches

The trick is survival. If you find the blueprint during a run, you must extract with it in your inventory. Once safely back in Speranza, open your inventory, select the blueprint, and click “Learn and Consume.” The physical item will disappear, but the recipe is saved to your account forever—meaning you won’t lose it if you die on subsequent runs.

If you’re tired of relying on low drop rates and want to bypass the grueling extraction grind entirely, you can check out platforms like U4N to buy arc raiders blueprints instant delivery and get straight to upgrading your workshop.

💡 Alternative Ways to Get Heavy Gun Parts

If you haven’t secured the blueprint yet, or if your stash of Simple Gun Parts is completely bone-dry, you aren’t completely locked out of heavy weaponry. The game features three alternative avenues to gather what you need.

1. The Seed Economy (Celeste)

Your quickest daily fix is visiting Celeste, the Seed Trader.

• Price: 15 Seeds per Heavy Gun Part

• Limit: 3 Heavy Gun Parts per day

If you log in daily and Max out Celeste’s shop, you will spend 45 Seeds total. This is a highly efficient shortcut for solo players who have extra cash but struggle to survive deep-map extractions.

2. Weapon Recycling

Look through your stash for high-tier or heavy weapons you no longer use. Dismantling a baseline heavy weapon like the Patina or Bettina I directly from your inventory screen yields a guaranteed return:

• Yield: 2× Heavy Gun Parts per recycled gun

This creates a useful loop. If you extract with an unneeded heavy weapon that takes up too much weight or stash space, shredding it down gives you the exact raw components required to build a gun that actually fits your build.

3. High-Loot Map Hotspots

If you prefer traditional looting, pull up your map during a drop and look for zones outlined in red, pink, or gold. These are high-value loot areas.

While these zones feature much higher concentrations of deadly ARC units and rival Raiders, they also boast significantly boosted spawn rates for rare materials. Diving into a gold-outlined sector and aggressively checking weapon caches is the fastest way to pull multiple physical Heavy Gun Parts out of a single match without spending a single seed.
