The lower was finished on a vertical milling machine.
I drilled out most of the material before cleaning it up with an endmill.
The mill was old and didn't have a DRO, so I had to count turns.
I made a couple of small goofs, but nothing that would affect function.
I've put a couple hundred rounds through it since it was finished.
Not a single hiccup with Federal XM193.
I haven't shot anything else through it, or shot it for groups.
