Confused about rigging assault rifle

I already placed a bone there but im not sure about it.Should keep that bone right there ? You know assault rifles getting hold by 2 hands.So should i keep it there or delete ? If delete , then how skeletal mesh will hold from that point ? Can someone explain? (Thanks )

Lol you don’t need a bone there. Only for the trigger to move, folding stock, etc. Unless it’s a control bone then it doesn’t matter where it goes.

Then how will he hold with other hand where don’t have a bone ?
