Will this match the blueing of a mini 14 rifle?

The finish builds up with every pass. Think of it like gentle, layered darkening. It isn't a perfect match--nothing short of complete re bluing will do that. This gets rid of bright areas of wear and it's not like paint at all.

Does it work for glock gen 4 made in USA?

Not so sure. The Glock is not blued, but has a different metal finish, Tenefer, or something like that. If that's worn thru to white metal already, then the pen should work.

dose it work on black oxide

Bluing is black oxiding, same thing
