Like mentioned above: I have a reference to the weapon as a variable with repnotify (its ether not replicated, replicated or repnotify) if you choose repnotify, UE automatically creates a function called “VariablesName”_RepNotify or something like that. this function gets called on server and clients, if (usualy the server) changes it.the variable itself is also replicated. you will call the attache to component in the function and everything should work fine. Hope that helps
