Hi, guys, i am new in this world…so i’ll ask a lot…i suppose. 
i am following some videos tutorial but as soon as i started i found a problem. when i start a new project, in particular first person blueprint, i can see the skeleton but the weapon is missing so in the bp viewport so in game when i press play. even if i can shoot and the position of the arms is right, i can’t see the weapon. i also check in the details under “owner” and the options are both unchecked. someone can help me please? 
thanks
Got the same problem too while watching tutorials, no idea what happened, any help?
have a look at this post
looks like the mesh was missed out for this build
