I see alot of people talking about moding their weapons, but for the life of me I cna;t seem to do it.
In the manual it says to pick the weapon you want to mod and the correct mod, but nothing happens.

Can anyone help?

Please dont double post your other posts already been answered,

You need the mod for the specific weapon you want to upgrade,
then move your mouse over the weapon in your inventory and click X,
now on the screen that appears click the weapon mod, it should now be attached to your weapon.

sorry about that, i had a slowdown , when i posted this topic, and i clicked on this twice on the execute button, then nothing happent so i did another thread, please, delete them all
