OK, so i remade this topic from mock bolts to external accessories. I was in need of a charging handle, a bolt catch, and a selector switch as well. So, i noticed that they were a bit pricey. I then saw a king arms set that comes with a everything i needed and then some. In the description it said it was made of zinc ally. Is zinc alloy strong? How well does sit stand against rust? I do like to rack my charging handle a lot so i need something sturdy.
