Long story short, they have sent them in for ballistics testing.. they said if they clock above a certain speed, the criminal charges will be applied. Otherwise, they can be returned in a week.
Luckily I haven't modified them in any way, so they should be safe.
In all likelihood, it should be fine, but this incident still leaves a bad taste in my mouth in how it played out.
All's well that ends well, I guess.
