How to read — the three builds below are calculated from part stats. The numbers are the finished weapon ergonomics, vertical recoil, horizontal recoil, weight and parts cost, and the brackets show the difference from the default build. The Modding simulator at the bottom recalculates the stats as you swap parts slot by slot. Scopes are personal preference, so they are left out of the recommendations.

Lowest recoil Ergonomics 78.5 · vertical recoil 43 · recoil −16%

The combination that cuts recoil the most. Ergonomics only breaks ties. Parts cost 62,062₽ (cheaper of flea market and traders; parts included with the gun count as 0₽).

Balanced = Max ergonomics Ergonomics 89 · vertical recoil 44 · recoil −14%

Keeps ergonomics at or above the default build and at least 60 (if this gun cannot reach 60, halfway between lowest recoil and max ergonomics) while cutting recoil the most. Parts cost 8,999₽ (cheaper of flea market and traders; parts included with the gun count as 0₽).

Build it in game · shopping list

Fit the parts from top to bottom in the in-game modding screen (a slot only appears after the part above it is mounted). Then save it as a preset inside the game — the game has no way to import presets from a website.

Parts in each dropdown are sorted by the current goal (the last build you picked). Changing a slot clears the slots under it and only required slots are refilled automatically. Your build is saved in this browser.

How it is calculated — ergonomics = weapon base + sum of part values; recoil = weapon base recoil × (1 + sum of part recoil modifiers). This is the same calculation as the in-game weapon screen (based on public analyses of the game code; no formula changes in the 2025-2026 patch notes). Like the weapon screen, ammo recoil modifiers, mastery and overweight penalties are not included (ammo: see the Ammo table). The game shows ergonomics clamped to 0-100 and its aiming effect stops at 100, so values above 100 are shown as 100 and get no extra credit. Conflicting parts are avoided, but some slot-position conflicts are missing from the data and may still be blocked in game. Prices are the flea market 24h average (PvP) and trader cash prices; barters are not included.
