Weapon modding is a deep system in Tarkov, allowing you to customize firearms to your exact specifications. The 'Preset' system (accessed by right-clicking a weapon and selecting 'Edit Preset') is invaluable for planning builds and checking stats before buying parts.
Key Stats to Consider:
- Ergonomics (Ergo): Affects aim-down-sights (ADS) speed and stamina drain while aiming. Higher is better.
- Recoil: Vertical and horizontal recoil. Lower is better for control.
- Accuracy: How tight your bullet spread is. Higher is better.
Experiment with different stocks, handguards, grips, muzzle devices, and scopes. Different calibers and weapon platforms have unique modding options. Completing Mechanic's 'Gunsmith' quests will teach you a lot about effective modding. Always consider the cost-to-performance ratio of your builds.
