good day.. i have several upgrades for my lazer rifle like the beam splitter and the long range mod for it.. but how do i put em on the weapon :S????

ro into the pipboy ad hilight the weapon as if you were going to repair it. There will be an option to modify just like repair. On the xbox repair is Y and modify is LB. Hit the correct button and it will bring up a list of the mods you have bought and you can select them and install them.

thank you cant beleave i was so blind to mis that
