How does weapon customization work?
Every handgun and machine gun has a Customize screen: your base weapon sits on a grid, and custom parts snap in when their connector icons match (circles, lines, and adapters must line up). threetimes compares it to a jigsaw—wrong placement gets rejected, and removing one part near the core can drop an entire chain.
Parts never appear on the character model; they only change numbers such as Charge Speed (CS), Charge Acceleration (CA), Bullet Focus (BF), Magazine Size (MS), and Weight (WGT). That is why scratch-heavy machine gun builds can look absurd on the grid while still following the same combat rules as the battle system tutorial.

The footage frame shows the Weapons list on the left and the part grid on the right—this is the screen you use for every gun mod, not a separate “gun shop” purchase.
Who crafts parts, and what do I need?
Tinkerers in Ebel City, Cranktown, and Albona craft parts from scrap (battle drops plus items you break down at the Ebel City Scrapper—check before selling unknown loot). Pay Rubies plus materials for scopes, barrels, grips, and magazines. Grenades and special ammo also come from the Tinkerer but attach to cases, not the socket grid. Pair grid work with the best gun setup scratch/direct split.
What should I upgrade first with limited Rubies?
Prioritize Charge Acceleration on your scratch machine gun (more charges per Hero Action—see Hero Action guide), then Charge Speed on whoever opens fights, then Magazine Size, always watching Weight so your case slot stays equipped (scratch vs direct damage).
Before Tar Man in Lucia, threetimes expects at least Top Sight + Rookie Grip on SMG-05 and basic handgun scopes—Hughes Power Station (Chapter 2) is where you pick up the MG High Barrel (+7% Charge Acceleration per TrueAchievements) and Scrapped Machinegun MS drops.
How do part types map to stats?
Neoseeker’s Basics of Customization table (community wiki, aligned with in-game tooltips) is the clean reference:
| Part family | Primary stats |
|---|---|
| Scopes / sights | Charge Speed |
| Barrels / adapters | Charge Acceleration |
| Hand grips / mounts | Focus (accuracy) and Rate of Fire (critical-state salvos) |
| Bullet magazines | Magazine Size |


Stacked scopes boost Charge Speed legitimately—leave connector paths open for magazine upgrades later.
What are common weapon customization wastes?
| Mistake | Why it hurts | Fix |
|---|---|---|
| Maxing Weight on one gun | Second slot (heals, grenades, special ammo) unequips | Remove outer grips; pick lower-WGT sights |
| Copying endgame grids early | Late Tinkerer recipes need scrap you lack | Follow threetimes chapter gates |
| Dual wield before averages beat case value | Two half-built guns < one modded gun + grenades | See weapon types |

Late grids fill every tile—fine for post-game Arena ranks, overkill before Chapter 2 bosses. Bezels never socket on guns; they only fuel Hero Actions (bezels and bezel shards). Mod the weapons that actually spend those runs.
