The Gunsmith questline is the longest, most expensive grind Mechanic will ever hand you in Escape from Tarkov 1.0 — and you can't skip it if you want the Kappa container. More than two dozen weapon builds, each demanding exact ergonomics, recoil and slot numbers, each one consuming the gun and every part you bolt onto it the moment you turn it in. Most players either stall on it for weeks or burn millions of roubles building wrong. This guide covers how the whole chain works in the current patch, the rules that trip everyone up, and the fastest, cheapest way through it (or past it).
Quick answer (TLDR): Gunsmith is a chain of weapon-modding tasks from Mechanic, running from Part 1 (player level 2) all the way to Part 25. Each part asks you to build a specific weapon to an exact spec — minimum ergonomics, maximum recoil sum, a required attachment, a slot/weight limit — then hand it over, which permanently consumes the weapon and all attached mods. Early parts need cheap guns (MP-133, shotguns, budget ARs); later parts gate behind high trader loyalty and need thermal scopes, suppressors and premium attachments worth hundreds of thousands of roubles each. Every Gunsmith part is a Kappa (Collector) requirement. Two rules cause 90% of "it won't accept my gun" posts: the weapon must have at least 60 durability, and you must empty the chamber and magazine before turning it in. Current state: the live 1.0.5 "Icebreaker" build; Tarkov 1.0 runs on a seasonal model (no traditional wipes), with Season 1 targeting July 2026.
What is the Gunsmith questline in Tarkov?
Gunsmith is Mechanic's signature task line and the single biggest test of the game's weapon-modding system. Instead of killing or looting, each part gives you a build brief: take a specific base weapon and modify it until it meets every listed requirement at once — typically a minimum ergonomics value, a maximum recoil sum, one or more mandatory parts (a sight, a suppressor, a tactical device), and a constraint like total slot count or weight.
The chain is long. It starts at Part 1 the moment you hit player level 2 and continues — gated by your level and your trader loyalty — all the way to Part 25. That's 25 separate weapon builds, each one more demanding and more expensive than the last. There is no shortcut around it inside the game: the parts unlock in sequence, and completing each one is a hard prerequisite for the next.
Why anyone tolerates it comes down to three things:
- It's mandatory for Kappa. Every Gunsmith part is a required quest for the Collector task, which rewards the Kappa container. No Gunsmith, no Kappa.
- The rewards compound. Later parts hand out high-tier loot and, critically, unlock trader barters and loyalty — Part 22, for example, unlocks a Mechanic Loyalty Level 4 barter for a Trijicon REAP-IR thermal scope.
- It teaches modding. By the time you've finished it you understand the attachment system better than any tutorial could teach you.
How does a Gunsmith build work?
Each part shows a checklist. You satisfy every line at the same time and the quest is ready to complete. The recurring requirements are:
- Minimum ergonomics — your build's ergo stat must be at or above the listed number.
- Maximum recoil sum — vertical + horizontal recoil must be at or below the cap.
- Required attachments — e.g. "a tactical device," "a suppressor," "a sight with X magnification." Sometimes a specific part is named.
- A constraint — maximum total slots, maximum weight, or "must be compact."
For example, Gunsmith — Part 1 (available at level 2) asks for an MP-133 pump shotgun modded to more than 45 ergonomics, fitted with a tactical/laser device and an extended magazine, kept under 850 recoil sum, and compact (no more than 4 mounting slots). As the in-game task brief from Mechanic puts it:
"Modify an MP-133 to comply with the given specifications." — Mechanic, Gunsmith – Part 1 objective (official EFT Wiki)
Complete it and Mechanic pays roughly ₽10,000 (scaling up with your Intelligence Center level), a sliver of +0.01 Mechanic rep, plus some bolts, screw nuts and slug ammo.
The thing every new player learns the hard way: completing the quest destroys the weapon and everything attached to it. You do not get the gun or the mods back. That single mechanic is why Gunsmith is a money sink and why planning each build to be as cheap as possible matters.
The two rules that break every build
If the game refuses to let you complete a part even though your numbers look right, it's almost always one of these:
- Durability must be 60 or higher. Every gun (and many parts) handed to Mechanic needs at least 60 durability. Buy fresh or repair before you build — a beaten-up flea-market base will silently fail the check.
- Empty the chamber and the magazine. A round left in the chamber or ammo in the mag will block the turn-in. Unload everything first.
A third, quieter trap: build the weapon in your stash, not in raid, and read the spec literally — "more than 45 ergonomics" means 46+, and the recoil cap is a hard ceiling, not a target.
Gunsmith level and loyalty gates
Two separate systems pace you through the chain:
- Player level unlocks each part. Part 1 opens at level 2, Part 3 around level 7, and the gates climb steadily — Part 16 needs roughly level 30, and the final parts sit in the high 30s and beyond. You physically cannot start a part before its level.
- Trader loyalty controls whether you can buy the parts. Many mid-and-late builds require attachments sold only at Mechanic, Peacekeeper, Skier or Jaeger Loyalty Level 2–4. If your traders are low, the part exists in your quest log but the components are locked behind flea prices or higher loyalty.
This is the real reason Gunsmith stalls: it's not the building, it's having a high enough PMC level and enough trader rep to source compliant parts without overpaying on the flea market.
The practical milestones worth knowing:
| Milestone | Player level (approx.) | What changes |
|---|---|---|
| Part 1 | 2 | The chain begins — cheap shotgun build |
| Part 3 | ~7 | Builds get more specific; flea market opens at level 15 |
| Part 16 | ~30 | Premium attachments and higher trader LL required |
| Part 22 | mid-30s | Unlocks a Mechanic LL4 Trijicon REAP-IR thermal barter |
| Part 25 | high-30s+ | Final build — closes out the Kappa requirement |
(Exact specs and level numbers shift between major patches — always confirm the current build for your part on the in-game brief or tarkov.dev before buying parts.)
The fastest, cheapest way through Gunsmith
You can't skip parts, but you can stop wasting roubles. The strategy that actually saves money and time:
- Do each part the moment it unlocks. Gunsmith parts unlock on your level and feed the next one; sitting on them only delays Kappa. Knock them out as you level naturally.
- Build the cheapest compliant version. Use a build calculator (the tarkov.dev Gunsmith builder is the standard) to find the lowest-cost combination of parts that still hits the ergo/recoil/constraint numbers. There are usually far cheaper parts than the "meta" ones that still pass the check.
- Buy bases fresh. A new gun from the trader is guaranteed 100 durability and saves you a repair before the 60-durability gate.
- Don't over-build. The quest checks thresholds, not perfection. Once you're at 46 ergo for a "more than 45" requirement, stop — every extra premium part is roubles you're about to delete.
- Bank parts you'll reuse. While the turn-in consumes that build, common attachments (rails, grips, basic sights) reappear across later parts. If you already own a cheap compliant part, build with it instead of buying again.
- Keep roubles liquid. The late chain eats hundreds of thousands of roubles per build in scopes and suppressors. Running dry mid-questline is the most common reason players abandon Kappa.
If your trader loyalty or level is the bottleneck — not the modding itself — that's the grind a service is built to remove.

Is the Gunsmith grind worth it?
If you're chasing Kappa, you have no choice — every part is required, so the only question is how you do it, not whether. If you're a casual or PvE-focused player who doesn't care about the container, the honest answer is that the mid-chain parts are a steep rouble and loyalty investment for rewards you may not need. The sweet spot for most players: do the early parts (1–10) naturally as you level since they're cheap and teach modding, then decide around the level-30 wall whether the Kappa payoff and trader unlocks justify the late-chain cost — or whether a boost is the faster route to the container.
Frequently Asked Questions
Is Gunsmith required for Kappa in Tarkov? Yes. Every Gunsmith part is a required quest for the Collector task, and Collector is what rewards the Kappa container. You cannot get Kappa without completing the entire Gunsmith chain.
Why won't the game accept my Gunsmith weapon? The two usual causes are durability below 60 (every gun handed to Mechanic must be at least 60 durability) and leftover ammo — a round in the chamber or rounds in the magazine will block the turn-in. Unload completely and check durability, then re-check that you meet every ergo, recoil and slot requirement at once.
Do you get the weapon and parts back after a Gunsmith quest? No. Completing a Gunsmith part permanently consumes the weapon and all attached mods. They are not returned, which is exactly why building the cheapest compliant version of each part matters.
How many Gunsmith parts are there in Tarkov? The chain currently runs from Part 1 to Part 25 — more than two dozen separate weapon builds, each gated behind a higher player level and, often, higher trader loyalty.
What level do you need for Gunsmith? Part 1 unlocks at player level 2. The gates climb across the chain — roughly level 30 by Part 16, and the high 30s and beyond for the final parts. Trader loyalty (Mechanic, Peacekeeper, Skier, Jaeger) separately controls whether you can buy the required parts.
What's the hardest part of Gunsmith? Not the modding — it's the cost and trader-loyalty gates on the late chain. Mid-to-late parts demand premium scopes, suppressors and thermals worth hundreds of thousands of roubles each, sold only at high loyalty levels, and every build is destroyed on turn-in.
