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 builder 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.

How it is calculated — ergonomics = weapon base + sum of part values; recoil = weapon base recoil × (1 + sum of part recoil modifiers). This formula matches the stats of all 163 default builds on tarkov.dev within ±1. Ammo recoil modifiers, weapon mastery and overweight penalties are not included (ammo: see the Ammo table). Ergonomics above 100 gets no extra credit in the recommendations. 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.
