This is second edition. I was looking at p.232 (custom weapons) and the playbooks pdf. I hadn't looked at p.28 which indeed lists the same tags as on the playbooks pdf.

What I don't get is that the way you describe it, hi-powered functions the same way as scoped but they are written out differently.
close/far implies to me that the weapon gains close or far depending on what it didn't have already. But then or +1harm at far would give you another option if the weapon already had far. Which would be an option within an option, which seems confusing.

So a on a handgun it's straightforward: it gains close/far
But on a rifle you would get a choice: it gains close/far or +1 harm at far
