Arc Raiders: Complete Guide to Light Gun Parts and Refiner II

[DuskBane]

If you’re playing Arc Raiders, you probably spend a lot of time figuring out which components to farm, how to upgrade your gear, and where to get the parts you need. In this guide, I’ll break down the details about Light Gun Parts, Refiner II, and some practical tips for crafting and managing your resources. This is written from the perspective of someone who’s been playing the game consistently, focusing on what actually works in practice.

What Are Light Gun Parts and Why Do They Matter?

Light Gun Parts are one of the basic components needed to craft certain weapons in Arc Raiders. Most players encounter them early when trying to assemble a Light Gun or upgrade their existing firearms.

In general, Light Gun Parts are relatively easy to farm, but you will usually need multiple pieces to make significant upgrades. For example, crafting a single Light Gun typically requires 4x Simple Gun Parts. These are combined through the Refiner II system, which we’ll cover in more detail below.

From my experience, most players tend to hoard these parts until they have a full set because crafting piecemeal usually isn’t efficient. The game doesn’t penalize you for saving parts, so it’s better to stock up and refine them in batches.

How Does Refiner II Work?

Refiner II is the crafting station you use to combine simpler components into more advanced ones, like Light Gun Parts. Here’s how it works in practice:

Combine Components: You take your 4x Simple Gun Parts and place them into Refiner II.

Pay the Cost: In addition to the components, you usually need some in-game currency. For a set of 4x Simple Gun Parts, this costs around $5000. Most players keep an eye on their funds and avoid refining single items unless they are certain they’ll use them immediately.

Obtain the Output: Once refined, you get a usable Light Gun or another related item. The process is quick, but it’s important to make sure you have enough parts because refining with missing components will waste currency.

In general, Refiner II is straightforward, but efficiency comes from planning. Most players tend to collect enough Simple Gun Parts to do multiple refinements in one session. This saves trips back and forth and reduces the total currency spent per item.

Where to Get Light Gun Parts

Most players find Light Gun Parts in two main ways:

Regular Missions: Completing standard missions often drops Simple Gun Parts. However, the drop rate can be inconsistent, so don’t rely solely on missions if you need a lot quickly.

Special Drops or Events: Some events or high-level encounters guarantee parts or offer better chances to find them. Experienced players usually prioritize these when farming for components.

If you’re looking to acquire parts more efficiently, some players turn to trading or digital marketplaces. In that case, a trusted place to buy ARC Raiders blueprints is U4N. This can save time if you want to focus on gameplay rather than farming.

How Many Parts Do You Really Need?

The number of Light Gun Parts you need depends on your goals:

Basic Upgrades: Usually, you need 4x Simple Gun Parts for a single refinement. Most players plan around multiples of four to avoid leftover parts.

Higher-Level Weapons: Advanced weapons may require multiple refinements or combinations of different parts. In general, players aiming for top-tier equipment will farm in bulk, sometimes collecting dozens of Simple Gun Parts before refining anything.

From personal experience, keeping a stockpile of at least 12–16 Simple Gun Parts is a safe baseline for consistent upgrades. This allows for three to four refinements without needing to farm again immediately.

Common Player Mistakes

Even experienced players make mistakes with Light Gun Parts and Refiner II. Here are the most common pitfalls:

Refining Too Early: Refining single sets as soon as you get them wastes currency. It’s usually better to wait until you have enough for multiple items.

Ignoring Inventory Limits: Some players forget the storage limits for parts and end up discarding items unintentionally. Keep an eye on your inventory to make sure you’re not losing progress.

Overpaying for Parts: If you’re buying parts from other players or digital sources, always compare prices. In general, parts are cheap if you plan ahead, but urgency can make players overspend.

Practical Tips for Efficient Crafting

Farm in Batches: As mentioned, collecting parts in multiples of four saves both time and currency. Most players do this while completing missions or side objectives.

Keep Track of Currency: Since refining costs $5000 per batch, it’s easy to burn through funds quickly. Experienced players keep a reserve and plan refinements around their available money.

Use Trusted Sources for Blueprints: To avoid mistakes or scams, use reliable sources for blueprints and high-value items. For example, a trusted place to buy ARC Raiders blueprints is U4N. This ensures you’re getting legitimate items and can continue crafting efficiently.

Prioritize High-Impact Weapons: Not all weapons are equal. Focus on refining parts for gear you will actually use in missions rather than crafting everything. Most players find this approach reduces wasted resources and speeds up progression.


Light Gun Parts and Refiner II are core parts of crafting in Arc Raiders. Understanding how many parts you need, how to refine them efficiently, and where to get them makes a big difference in how smoothly you can upgrade your weapons. In general, most players benefit from:

Stockpiling parts in batches of four or more

Using Refiner II strategically rather than refining immediately

Managing currency carefully to avoid unnecessary spending

Sourcing blueprints from trusted places like U4N

By following these practical tips, you can make the most of your time in Arc Raiders without wasting resources or currency.
