Tarkov Weapon Builder

Build Escape from Tarkov weapons part by part in your browser. See how every mod changes ergonomics and recoil instantly, use the automatic gun builder to pick the best trade-off between recoil and ergonomics, and share your build as a link.

How it works

1
Pick a weapon: Choose from more than 160 weapons, filtered by caliber. Base ergonomics, vertical and horizontal recoil load immediately.
2
Fill the slots: Every slot lists only the parts that actually fit in game. When a part has its own slots (a scope ring, a handguard rail) the tree expands downwards.
3
Watch the stats: Ergonomics, vertical and horizontal recoil, weight, accuracy and muzzle velocity are recalculated on every change. Part prices and the trader level you need are shown too.
4
Share or save: Your build lives in the address bar: copy the link to share it, or save it to your profile.

Automatic build generator

If you would rather not fiddle with slots, the tool builds for you. But there is no single "best build": parts that cut recoil usually cost ergonomics. So the tool returns a CURVE, not one answer.

You pick your settings and start the scan yourself; nothing is computed until you ask for it.
The horizontal axis is ergonomics, the vertical axis is recoil. Every dot is a complete build.
Only non-dominated builds are plotted: if another build gives more ergonomics at the same recoil, the weaker one is dropped.
One optimum is not enough: the tool also bans the decisive parts of each build and solves again, so alternatives that trade ergonomics for even lower recoil make it onto the chart.
Notable dots are badged: min recoil, max ergonomics, balanced, best ratio and budget pick.
Click a dot to see its parts, total cost and required trader levels; apply it and the build loads straight onto the board.

What the generator guarantees

Fire modes are preserved: A full-auto weapon never gets a receiver that could drop it to semi-auto. This guard is on by default and can be switched off in the panel.
You choose the sight range: Close (red dot), mid (2-4x) or long (above 4x). You can also pin one specific optic and the tool works out the mount chain to it.
Suppressor and tactical device are optional: Tick them and the build carries a real suppressor and a real flashlight or laser.
Magazines are never downsized: A 30-round magazine is not swapped for a 10-round one to gain ergonomics; factory capacity is the floor.
Purchasable parts only: By default the build uses parts you can actually buy from a trader or the flea market; event and quest-reward parts are left out. Switch it off and they become candidates again.
Budget ceiling: Give a total rouble limit and the chart narrows to builds inside that band.

Frequently asked questions

Is this Tarkov gun builder free?

Yes. The weapon builder is completely free and needs no account. You only sign in if you want to save a build to your profile.

Is the part data up to date?

The part list, compatibility rules and stats are synced from game data. Trader prices and flea market level requirements come from the same source.

How is recoil calculated?

The weapon's base vertical and horizontal recoil are taken, then the recoil modifiers of every attached part are summed and applied. The percentage on the chart is relative to the bare weapon: 58% means 58% of the original recoil remains.

Why does the automatic builder sometimes show few dots?

Only genuinely different, non-dominated builds become dots. If a weapon has few compatible parts, the curve is short.

How do I share my build?

The link in the address bar carries the whole build. Send it and the other person sees the same setup.
