How to Upgrade Weapons in Jagged Alliance 3

Modifying your weapon doesn’t always work. The game will select the character with the highest Mechanical skill to make the upgrades, but there is a chance that the upgrade will fail. Each time the upgrade fails, your weapon will lose Condition, which increases the likelihood of it jamming. For this reason, we suggest trying mods that are easier to accomplish until your character’s Mechanical skill is high.
