I tend to do that. I overthink and I notice this most silly things, but I can't put it out of my mind. I just don't know what it is supposed to look like. I don't want it to be mounted incorrectly (it seems like it'd be hard/almost impossible to mount incorrectly, though).

That's the order I plan on doing it. I was excited to get up and go to the range today, but my back (damn genetics) had other plans. I can barely walk. Looks like I'll be going sometime this week.
