I don’t mind but that is all I have 
(the other things are WIP and i don’t want to confuse because they don’t work)
Check your “attach to actor” do you have a custom socket in your skeletal mesh , if not ,you can attach “Camera”-“In parent” to test will it work,
Also make sure your weapon has a mesh so it casts shadows , sometimes it gets attached out of your FOV and seeing the shadow move with you, can tell you if are you going in the right direction.
