In 3079, you are able to upgrage your wepons. Using the upgrading compoments, you can put it onto any wepon or armour. Upgrades randomly vary, from every type of skill. Each wepon or armour can only be upgraded once. When upgrading, select the compoment, and put it ontop of the the wepon/armour you wish to upgrade. Upgrading can sometimes fail, and the compoments can brake, but you can reduce the chance from braking, if you upgrade your engerneering skill.
