      thank you! i don’t remember the game explaining this and the only help i get is where to buy weapon mods as if that isn’t obvious (gee why don’t you check the stock of anyone selling shit)

    • Kieran

      On xbox hover over the weapon you have the mod for and i think its left bumper and then click A.

    • Eric Chang

      How do you attach a weapon upgrade on the Xbox?

    • Maxim

      I don’t know if it’s a glitch or what, but some of the vendors listed never have weapon mods and most never upgrade their inventory. Example: Knight Torres, even after I became Idolized with the Brotherhood never had any mods or even Misc. items for that matter. Michelle doesn’t even sell guns, she only sells food and non-weapon crap.

      This is the Xbox version by the way.

      Do you have to do or use something to attach these upgrades cuase i can purchase from these places but an not use them ?

        You need to install these into your weapons. Go to weapons, pick the weapon you want to install any upgrade, press L2.

          In case you are on PC, choose the weapon, and press E.

      So am I to assume that I’m just supposed to buy items from these people or what exactly ?

      Thanks
