Part 7:
Many AR's have pins that are very tight and hard to push, requiring a tool (bullet tip, punch, etc) to push them in.
The tool tends to slide off the rounded head of the pin and scratch the lower.
I chuck mine in the lathe and put a slightly concave indentation on them.
If you don't have a lathe, you can chuck the pin in a drill and use a stone on your Dremel and do the same thing.
