You cannot actually craft Simple Gun Parts in ARC Raiders right now; they only drop or are bought, and the in‑game wiki even flags them as the one gun‑part tier that “cannot be crafted.”

Can you craft Simple Gun Parts?

  • Simple Gun Parts are an uncommon topside material used to craft, upgrade, and repair many weapons, and to refine into Light, Medium, and Heavy Gun Parts.
  • The item page notes that Simple Gun Parts are the only gun‑part variant that currently cannot be crafted from a blueprint recipe.

How to actually get them

Players treat Simple Gun Parts as a farmable drop and shop commodity rather than a craftable resource.

  • Kill small ARCs like Hornets and Wasps; they are repeatedly cited as reliable sources for Simple Gun Parts when farming in the open world.
  • Dismantle green‑rarity weapons to turn them into Mechanical Components and Simple Gun Parts, which many players use as a steady source of both resources.
  • Buy from vendors such as Celeste/Celest, where Simple Gun Parts can periodically be purchased in small stacks, sometimes in exchange for seeds or similar currencies.

What you can craft with them

Once you have a stockpile, the crafting system opens up quite a bit.

  • At Gunsmith workstations, Simple Gun Parts appear in many weapon recipes (Anvil, Arpeggio, Burletta, Ferro, Hairpin, Il Toro, Kettle, Rattler, Stitcher, and their higher tiers).
  • At Refiner 2 , you can turn 4× Simple Gun Parts into 1× Light, Medium, or Heavy Gun Parts, assuming you have the blueprints for those tiers.

Repairing and recycling

Managing Simple Gun Parts is also about keeping weapons running and squeezing value from extras.

  • Weapon repairs often require Simple Gun Parts plus Mechanical or Metal Parts (for example, repairing higher‑tier Anvil or Il Toro variants scales up the number of Simple Gun Parts needed).
  • If you are overstocked, recycling or salvaging items containing Simple Gun Parts yields Metal Parts, which can then feed back into other crafts.

Quick takeaway

  • There is no blueprint or bench recipe to craft Simple Gun Parts themselves at this time.
  • Treat them as a drop/loot and vendor resource : farm small ARCs, dismantle weapons, and check traders frequently to keep your stock healthy for late‑game weapon crafting.
