Craft Medium Gun Parts (Refiner 2 + blueprint)
Step 1: Find the Medium Gun Parts blueprint. These appear in high-value weapon caches, breach crates, and other gun-focused containers, especially in militarized areas. Keys and access items improve your odds because they open the best rooms.
Step 2: Learn the blueprint at your Workshop so the recipe becomes permanently available. Once learned, you can craft the part anytime you have materials.
Step 3: Upgrade the Refiner to Level 2. This upgrade uses specific components such as Toasters, Fireball Burners, and ARC Motion Cores, so plan a short materials run if you are missing any.
Step 4: Gather 4× Simple Gun Parts. These come from world drops, vendor trades, and recycling; see the section below for fast ways to stock up.
Step 5: Craft the part at Refiner 2. Select the Medium Gun Parts recipe and convert 4× Simple into 1× Medium; the blueprint gate must be cleared for the option to appear.
Buy Medium Gun Parts (Celeste vendor)
Step 1: Check Celeste’s inventory in Speranza. She can stock Medium Gun Parts among other materials, and her offers rotate on a timer.
Step 2: Trade for the parts when they appear. If you’re mid-upgrade, prioritize buying enough to complete a full weapon tier bump before the stock turns over.
Loot Medium Gun Parts (scavenging, caches, Raider/Security)
Step 1: Prioritize Raider and Security loot sources. Weapon cases, security lockers, and faction stashes have the right loot table for Medium Gun Parts.
Step 2: Hit high-value rooms and breach crates. Weapon caches and special storage rooms are strong candidates for gun materials.
Step 3: Bring the right access items. Keys and power cells let you open locked areas that hold higher-tier containers and better drop chances.
Step 4: Sweep contested combat zones and search bodies. Raiders—both AI and player—can carry parts or blueprints you need.
Get Simple Gun Parts quickly (needed for crafting)
Step 1: Farm small ARCs like Hornets and Wasps. These enemies show up across all maps and drop Simple Gun Parts frequently, speeding up your Refiner inputs.
Step 2: Trade for Simple Gun Parts via Celeste when available. She exchanges seeds and other trade goods for essentials; Assorted Seeds are commonly obtained in the field or by recycling certain plants such as Great Mullein.
Step 3: Recycle spare Gun Parts to reclaim Simple. Light, Medium, and Heavy Gun Parts can be broken down; Medium specifically returns 2× Simple when recycled.
Note that Simple Gun Parts themselves are not craftable, which is why farming or trading for them is the fastest path to more Medium Gun Parts.
Recycling and salvage conversions (manage your stock)
| Action | Result |
| Recycle 1× Medium Gun Parts. | 2× Simple Gun Parts. |
| Salvage 1× Medium Gun Parts. | 1× Simple Gun Parts. |
Step 1: Use recycling when you overshoot. If you craft or loot more Medium than you need, recycle a few to quickly refill your Simple stack for the next upgrade.
Step 2: Keep a small buffer of Simple on hand. A steady Simple reserve prevents stalls when you unlock a new blueprint or want to batch-craft Medium Gun Parts.
