Every URX I’ve had, regardless of version, was installed by KAC. I trust them to do an unpinned GB. I think the ease of installing a pinned GB has been discussed well enough. I’ve done plenty of Geissele installs and they are super simple. I’m sorry that I can’t speak to shops, as I haven’t used any. JoshNC is a wizard at making FSB look like it was designed to be a low pro pinned GB.
