Thanks I have followed the same step but i can't do it can you please provide a video for this and grenade option see image below.The scope setup is described on this page: https://opsive.com/support/documentation/ultimate-character-controller/items/actions/usable/shootable-weapon/
Then Whats the purpose of Scope camera why when i click right click i can see the view from scope camera. Please help. i have added scope as per your documentation is shown in the previous thread.That will likely take some scripting in order to do. You'll need to change the anchor position of the camera so it points to the weapon, and then adjust the look offset of the camera's view type.
