ok, just to claify things, i am not talking about bolts, i am talking about the little cover piece on m4 aegs that look like a bolt. I am trying to put a g&p "mock bolt" onto a madbull body, and i am trying to find out if the g&p mock bolt will fit onto an ics charging handle. I know the ics charging handle comes with a mock bolt, but i want a g&p mock bolt instead.
